Buying guide

Even if you have power cut for a few minutes, you potentially stand to lose a lot of data – we’re talking from a business perspective. Imagine a power cut in your office (reason notwithstanding) and people not having had saved the work they have been doing – you should be scared to think how much business data gets lost. And then everyone having to do the same work they had been going all this while – it’s major time lost. This situation can be managed with Uninterruptible Power Supplies (UPS). As the name suggests, Uninterruptible Power Supplies ensure continuous power supply to vital electronic equipment so that no data is lost and no piece of equipment is damaged.


Choosing your Uninterruptible Power Supply


How much power backup do you need?

The basic premise of buying Uninterruptible Power Supplies lies in calculating how much power you will need to run all the pieces of electronic equipment for which you need uninterrupted power supply. Once you have done the calculation, make sure you purchase an Uninterruptible Power Supply that has 20% to 25% more output watt capacity than what you need. There is another bit of calculation you need to do – you need to figure out the time for which you need the power backup. It is possible you only need uninterrupted power supply for a few minutes – time enough for you to shut down all your computers etc. Or it is possible that you want the backup for as long as there is no power supply. In that case, you need a more powerful Uninterruptible Power Supply.


Important features in Uninterruptible Power Supplies

The different models of Uninterruptible Power Supplies have different features and you should choose the features as per your need. Some of the features worth looking at include:


  • Surge protection – if there is any spike or surge, all your pieces of equipment are protected against it.
  • Overvoltage protection – If there is overvoltage, the UPS can protect all the connected equipment.
  • Online operation – this ensures that there is no transfer time gap to the battery.
  • Pure sine wave output – if you have sensitive electronic equipment connected to your Uninterruptible Power Supply, pure sine wave output ensures perfect supply of power to these pieces of equipment.
  • Brownout protection – this feature ensures that the voltage level is maintained without the UPS having to use power from the batteries.
  • Battery backup – this feature ensures that there is backup power when there is power outage.


Space required for Uninterruptible Power Supplies

The amount of space you have also decides which of the Uninterruptible Power Supplies you should choose. There is the tower type Uninterruptible Power Supply that stands upright and can be placed on the ground or on a desktop. There is also the rack mount Uninterruptible Power Supply that is mounted on rack enclosures measuring 19 inches. This UPS needs more space.


Buy a scalable Uninterruptible Power Supply

Scalability is another important point for you to consider in Uninterruptible Power Supplies. Every UPS has a fixed number of outlets that connect to the pieces of equipment. Today you may only have five pieces of equipment and you would naturally be inclined to buy a UPS with five outlets. But why not look at Uninterruptible Power Supplies with 10 outlets (for example)? This will allow you to connect more pieces of electronic equipment in future. When you increase the number of electronic gadgets, you will then not need to buy a new UPS.
