Best UPS for PC in India – Complete Buying Guide

If you are in India, you should be aware of the power situation here. Moreover, the power situation is not bad everywhere but there are remote cities and villages where you will experience frequent power cuts. While the situation has improved to a considerable extent over the past few years, a 100% uptime cannot be expected in most of the regions. That is exactly where a UPS is much needed and essential. While the situation seems to have improved over the years, it is still risky enough to use expensive equipment without protection. From that perspective, it may be a good idea to check out the best UPS for PC in India to find out which are good to buy

What is a UPS?

A UPS is an Uninterrupted Power Supply. That in itself should be clearly understandable and let you understand what exactly is a UPS. UPS is designed to provide emergency power for different loads to different devices. They come in handy when the regular power supply fails, and power supply to the critical systems is not affected. 

A UPS system comes with an almost instantaneous power resumption through the power stored in the batteries. The run time is considerably less and gives an opportunity to save your work and shut down your system. There are some systems that would help you work with the automatic backup. 

Some high-end UPS systems would be helpful in keeping the devices running for several hours even when there is no power supply, and you are not around. 

Factors to consider when buying the UPS for PC in India

Before you move ahead to look for a product, it should be practical enough to consider a few select factors worth considering. This will help you make the right choice in terms of the best products and features. 

Here are a few select factors you should give a thought to:

1. Power Points2. Power3. Run time4. Warranty5. Cost6. Additional features
Also referred to as the outlets, these will determine the number of devices you would be able to provide backup using your UPS. This will be dependent upon the type of business you are running. If you need a considerably good number of devices, it would be a good idea to check out for more number of outlets. 
Power capacity is the next important factor you would need to consider. If the UPS cannot provide enough power to all the connected devices, it would not serve the exact purpose it is purchased for. The power is referred to as the VA. This is one of the most important aspects you need to give a thought to if you really want a value for money proposal. Ideally speaking, you should opt for a rating of 1.6 times your actual need. For instance, if your total need is 500 Watts, go for a UPA with 500 x 1.6 = 800 VA. 
This is also known as the duration of operation or UPS back up time. For most of the small-time usage requirements, you will want to have a run time of around a few minutes, so that you can save the work and shut down your device. However, there may be situations where you would want to continue working. Those scenarios would need at least one hour of backup.
This is yet another factor you would want to focus on. We would advise you to opt for a warranty period of at least 2 to 3 years. Also, check if the batteries can be serviced from time to time so that they can be kept in good status.
This is one of the most important aspects you would want to focus on. Strike the right balance between the cost and usability when buying a UPS. Make a checklist of your exact needs and choose the right UPS that meets those needs. Anything below or above the exact needs you may have won’t be practical.
While most of the UPS devices are made for a singular purpose of providing a power supply when the power goes off. However, a few additional features would be a little essential. Some of them can be a battery disconnect notification, USB connectivity, and a few software utilities as well

How to Calculate UPS Capacity Required?

A UPS is normally rated in VA or Volt-Amps. This measures the maximum Volts x Amperes that it can deliver. Do note that there is a huge difference between the power consumed and the VA rating. It is quite important to calculate the VA rating that you require for your devices and needs. If you go wrong with your calculations and drain the UPS beyond its rated capacity, you may end up damaging the life of the battery and shorten the life of the UPS to a considerable limit.

A simple way to calculate the exact VA rating for your power requirements, you will need to go through a proper analysis of the power capacity of all the devices you would want to connect. To begin with, calculate the wattage of all the devices you would want to connect to your new UPS. Once you arrive at your total wattage load requirement, you can apply the following formula: 

1.6 * Wattage Load = Minimum Volt-Amperes (VA)

This should provide you with the minimum VA rating that your UPS should have. There is no harm opting for a UPS with any higher VA rating than the one you have calculated. 

However, there are no calculations available for arriving at the exact run time or back up time. 

Yet another option would be to use the following formula. Please note that this method will work only when your devices have a labeled Volt and Amp description. 

  • List out all the equipment that you want to be protected by the UPS. 
  • List the Volt and Amps for each of them. 
  • Simply multiply Volts by Amps to get the Volt-Amps. 
  • Add all the VA subtotals. 
  • Multiple the VA total by 1.2. This is done to arrange for the expansion. 

Use this grand total to arrive at the right type of UPS for your needs. 

What Situations Does a UPS Can Address?

There are several power problems that can considerably affect your computer and the normal functioning that you would expect from it. Let us check out a few common power problems that we may come across. 

Power problems can hit you at any time. The lightning can strike the electrical substation and electrical poles. This can subsequently cause problems in equipment hundreds of meters away. 

A few electrical disturbances that can affect you would include:

1. Spikes2. Surge3. Blackout4. Brownout5. SAG6. Noise
A spike is a sudden increase in the voltage of the electrical supply. This can only happen for a few milliseconds. However, it can affect you seriously enough and damage your devices. The causes that can result in spikes can include lightning during the stormy weather or electrical lines falling on the ground due to some unforeseen circumstances like accidents and causing spikes. This can result in data corruption or a damaged hard drive. 
This is, again a short term increase in the supply voltage. This can last longer than the spike. This can result from the sudden switching off of large equipment like air conditioners. The surges can damage the delicate electrical components. This can even result in a high degree of dissipation of heat.
This is one of the common scenarios that we would normally come across. The Blackout refers to the complete loss of power. The total blackout can be a result of a critical failure at the power station or the supply grid. Other reasons that can cause the issue may be thunderstorms, accidents, lighting, and other wide range of reasons. The blackout can cause a loss of unsaved work. In some extreme cases, you would find that the entire hard drive fails to show the content. 
The supply voltage may go down for a longer time is referred to as Brownout. This can continue to affect you for a prolonged period. It can at times, last several hours. This can be caused by switching on larger equipment. There are several other reasons like over demand for utility power. This can cause the disruption of data and file allocation. This can make your device go into power on and power of status for prolonged periods of time. This can also result in the dissipation of a high amount of heat. 
This is almost similar to Brownout, but the effect will last only for a shorter time period. The causes would be similar to what causes the brownout. Even the results would be similar to what can be caused by a brownout effect. 
The noise is caused due to interference. These interferences would include EMI (Electronic Magnetic Interference) and RFI (Radio Frequency Interference). In fact, the interference is referred to as Noise. The major cause that can result in the issues would be the radiation from high energy equipment. These devices would include welders, radio transmitters, fluorescent lights, and electric switching equipment. The sine wave suffers a disturbance because of the superimposed and distorted signal. Noise can result in keyboard lockups and can even result in data corruption. 

The Watts to VA UPS Calculator – How to choose the right type?

It is quite important to note the difference and relationship between Watts and VA when choosing a UPS. The actual power is measured in Watts and indicates that part of the power flow, which results in the consumption of energy. 

There are other portions to the energy, one of them being Reactive Power and another Apparent Power. Reactive Power is that part of the power flow that is due to stored energy. The Apparent Power is the mathematical combination of real and reactive power. 

If you are looking for the right option for calculating the Watts to VA UPS calculator, the following formula would be helpful enough – 

Watts = VA * Power Factor or VA = Watts / Power Factor

If your equipment is rated in Amps, you will need to convert it into VA. The formula for converting Amps to VA would be as follows –

Single phase: Multiply amps by voltage

Three phases: Amps x volts x 1.732

Most of the equipment available currently are rated in Watts; the above formula can be the right choice for sizing up a UPS. 

How Long Does a UPS Battery Last?

Well, there are two variants to that question. How long does a UPS battery last or what exactly would be the lifetime of a UPS battery? The second question would be how long would the UPS be able to provide the backup under ideal conditions. 

Of course, you cannot expect a UPS to last forever. The exact lifetime of a UPS will be dependent upon the components used in the manufacturing. Most of the UPS systems last a minimum of 12 to 13 years. However, it should be noticed that the lifetime of the battery on a UPS may be dependent upon multiple factors. It can be dependent upon the usage conditions of the UPS; the maintenance levels used for the UPS can also be a deciding factor. On average, a UPS battery should last a minimum of 3 to 5 years. 

The second question is how long does a UPS battery last in terms of backup that it provides. Unfortunately, there is no specific calculation that can help you answer that query. Questions like how Long Does a 1500VA UPS Last may not be easy to answer. There are several factors that can affect the actual battery backup provided by your UPS. 

What is the difference between UPS and inverter?

Both UPS and inverters are designed to provide backup for the power systems. Their functionality and principle of working remain almost the same, with a few minor differences. The key difference between an inverter and UPS is the switching from mains to battery power. 

The UPS comes with a battery and supplies the power when the power outage happens. It can be quite helpful in addressing the shorter duration of power outages. The Inverter, on the other hand, inverts the direct current into alternating current. 

The following chart should be helpful enough in arriving at the right comparison – 

Features and Particulars UPS Inverter
Switching over Immediate Takes a while
Backup  Electrical  Electronic
Types Offline, Online, Line interruptive or Standby UPS Stand Alone and Grid Tie Inverter
Connectivity  Connects directly to the equipment Connects to the battery 
Cost Less expensive More expensive
Power Supply duration Shorter period Longer period
Protection for Voltage fluctuation Available Not available
Application areas Domestic and industrial use Domestic use alone


What are the situations where you would want to opt for UPS or Inverter? When you are opting for the same power requirements, a UPS unit may be a little expensive when compared t an inverter. In fact, a UPS comes with additional components and functionalities, and that is exactly what increases the cost. 

If your devices are in need of a continuous power supply, the UPS would be what you should prefer. An inverter will introduce a slight gap between switched off power and inverter switch on. A good example would be a data center that you would not want to go without power. In the case of the home lighting systems or other systems, you can tolerate the slighter degree of disconnection. 

Yet another difference between the UPS and inverter would be that it comes with a rectifier built within and does not require a separate charging controller. An inverter, on the other hand, will require a separate controller. Hope the difference between UPS and Inverter is now clear to you.

Types of UPS

Ideally, UPS systems are available in three different categories. In fact, there are two major types of UPS systems that can be useful for your needs – Online and Offline

Offline UPS Systems
Also referred to as the standby UPS, these can detect a power failure and immediately switch to the battery mode. These are best designed for short term and battery-powered back up for a shorter duration. These UPS systems are designed to receive the power and store it until it is actually needed. 

Offline UPS systems can be one of the best options if you are facing surge issues. The UPS can detect a power failure, voltage sag and high voltage issues. In any of those scenarios, the UPS will switch power to the battery and keep providing it until the power supply is restored. An offline UPS works on the square wave and modified square wave modes. 

The Standby or Offline UPS system can work efficiently for the common power failure issues. They are ideally available in capacities of 600 VA or lower. This can be one of the best options for home usage or single computers on business usage. 

Line Interactive UPS Systems
This should be an excellent option for catering to irregular voltage issues. The Line Interactive UPS systems can be a good alternative for both low voltage or high voltage. These UPS systems come with Automatic Voltage regulator or AVR. 

Since the AVR systems ensure that both boost and buck, so thus you have no issues with respect to the power consumption, it is the best option for prolonging the battery life as it supplies the battery power only when it is absolutely required. They operate on sine wave and square wave modes. 

The Line Interactive UPS system can be a little expensive when compared to the standard UPS options. You can buy the 0.5 kVA to 5 kVA. 

Online UPS Systems

Online UPS systems are quite effective and efficient enough but can be quite expensive. The online UPS devices work on the basis of delta conversion or double conversion. Both the techniques have been observed to be quite efficient enough. 

The Double Conversion works on the following lines – the AC power is directed to the rectifier where it is converted into the DC power. It then travels to the battery. The current then moves to the inverter where it is converted back into AC power and supplied to the equipment. This will help your devices to receive continuous power without interruption. The technique is referred to as Double Conversion because of the two stages of conversions used in the process. 

The delta conversion works in a slightly different way. A part of the power is directly sent to the computer or other devices, and a part is sent for the conversion. Whenever a fluctuation is detected, rectifier stops the direct supply of power and supplies the battery power after converting it into the AC power. 

Best UPS Brands in India

UPS is an important element if you want to make the best use of the digital revolution. In case you are looking for the best ever experience in terms of the performance, it is essential to give a thought to the best UPS brands so as to ensure good quality performance. 

In this perspective, here are a few top-end UPS brands that you can indeed check out. 

  • Luminous 

This is the best and most popular UPS brands in India. The portfolio of the company includes UPS, batteries, inverters and a host of other power backup systems. The company has a total of seven manufacturing plants spread across multiple locations in India. 

  • Microtek

A brand known well enough for inverters and power backup systems, Microtek has been one of the first choice UPS in many business applications. The huge PSP that the company has based its performance would include the excellent after-sales service that it has build its business on. The company has over 300 service centers and 50 service stations across the nation. Microtek also has five manufacturing units across the country, and for me, this is the best UPS brand in India. However, other brands are good too.

  • True Power

The power backup solutions company was established back in 1993 and become a top-end UPS manufacturer. The company is quite innovative in its approach. They do have a state of the art manufacturing unit along with a specialized R & D section as well. 

  • Amara Raja

Amara Raja is yet another prominent name in the Indian UPS industry. In fact, it has been one of the huge names that have shaped up the concept of UPS in India. They have also been into power management and storage options and also deal in renewable energy sources like solar. 

  • Genus Power

The sophisticated R & D is what makes Genus one of the best options you would want to opt for. In fact, it is one of those rare industrial units that has its research section approved by the Ministry of Science and Technology. The company has five manufacturing plants in different parts of the country. 

How does a UPS System Work?

Well, the basic principle that a UPS works would be on similar lines as a battery does. It comprises of a  few components that store the energy and deliver it when needed. A UPS features a few components like inverters, batteries, static switch and more importantly, a rectifier. 

The rectifier receives the power supply in the form of AC current and converts it into DC current. The rectifier receives the energy and converts it into DC power and performs another secondary function where its battery charging voltage just like a charger. 

The battery inside the UPS acts as a storage of energy. It consists of several cells in series and holds the supply in the form of DC current. When the power supply is normal, it converts the electrical energy into the chemical energy and stores it within its cells. When the power supply fails, the chemical energy is converted into the electrical energy and supplied to the inverter. 

Inverter, as we are already aware, converts the DC power supplied by the battery into AC power. The inverter normally consists of inverter bridge control logic and filter circuit. The final part, the static switch, performs the task of switching between the direct current and the stored energy. It is a contactless switch and facilitates an easier switching between the two modes of power supply.

How to take care of your UPS – The UPS Maintenance?

Most of us tend to believe that a UPS does not need maintenance, and it is a maintenance-free battery. Do note that this is a myth. In many cases of UPS failures, it has been found that the failures are due to an abnormal load or lack of maintenance. 

Make sure that you follow a few important maintenance tips and go through the right kind of maintenance regime for enhanced performance of your UPS – 

  • Make sure the environmental temperature is optimal for normal operation of the battery. The best ambient temperature recommended by most of the battery manufacturers ranges to up to 20 to 25 degree C. An increase of even 10 degree C is expected to reduce the battery life by 50%. Increased temperature can induce an increased chemical activity within the battery and thus can adversely affect battery life. 
  • Make sure that you are opting for the frequent charge-discharge cycles at periodic intervals. This will ensure a better life span for your battery and the UPS in general. It is advisable to discharge the UPS battery once every two or three months for a better life span of your UPS battery. 
  • Take care of safety requirements. Electricity and electrical power can be quite fatal. A single wrong step can cause fatalities and even death. Ensure that you are abiding by all the safety recommendations provided by the manufacturer. If you are unsure of something related to your UPS, make sure that you refer the case to a professional who knows what to do and when. 
  • Create a maintenance schedule and abide by it. Many businesses create a schedule of maintenance just for the sake of compliance and seldom follow it. Remember that the maintenance schedules are designed to improve the efficiency of any device. Keeping the records and following every maintenance schedule should be helpful enough in getting the UPS work for a prolonged period of time. 

To make things work better, make sure that you have assigned the maintenance tasks in a clearly defined manner. There should never be any sort ambiguity about who is doing what. This will help you avoid the unneeded mess and help you reach out the best results. 

It should be ideal to leave the maintenance of your UPS to someone who is aware of the UPS and their working in a professional manner. Instead of doing it yourself, it would be advisable to go with the professional assistance even if it tends to cost more. This can go a long way in helping you address the downtime effectively and help avoid the risk to lives. 

The Concluding Thoughts

That was a complete discussion on the UPS systems and how effective they can be in taking care of your computer. We assume that the information contained here in the discussion should have helped you arrive at the best solutions for your needs. If that helps you arrive at the best solutions in terms of power backups and other requirements, our efforts would be paid off.
