UPS Sizing Calculator | HOW TO SIZE A UPS SYSTEM?

In today’s world, almost all businesses rely on important equipment and computer systems. So, it’s really crucial to have a backup power system called a UPS (uninterruptible power supply). This UPS helps protect your network and machines in case the power goes out or there’s a sudden surge in electricity. However, to pick the right UPS, you need to figure out how much power it needs to provide. UPS Sizing Calculator will help you to figure out this.

To do this, you should find out how much power all your equipment uses. Think of it like adding up the power needed for each device. This power is measured in something called VA (Volt-Amps). You also need to know how long you want the UPS to keep things running when the power is out.

In simple terms, sizing a UPS means figuring out how much power your stuff needs, so you can choose a UPS that can handle it and keep things running for as long as you need it when the power is out.

Identify Which components need to be protected by UPS.

You don’t have to protect all your equipment with a UPS. To choose the right UPS size, you should separate your equipment into two groups:

Critical Load: These are the things you can’t afford to lose power, like important computers and machines you use for work.

Non-Critical Load: These are the things that can handle losing power for a while, like some lights or less important devices.

By doing this, you make sure you don’t buy a UPS that’s too big and expensive. You focus on keeping only the most important stuff running during a power problem.

How to calculate the size of UPS System? What do you need to know?

When getting a UPS system, the main thing is the backup time of UPS to safely turn off your equipment when powers go out. Normally, it stores electricity in a battery and uses it when there’s a power problem. The UPS’s power is measured in something called VA rating.

But, when picking a UPS, it’s not just about the VA rating. It’s more important to know how much stuff you’re connecting to it. This is called the ‘load.’

When you know how much power all your equipment uses, add up those numbers. This gives you the minimum UPS size you need.

But here’s the important part: It’s not a good idea to use a UPS at 100% of its capacity. It’s safer to have some extra room. So, take your total number and multiply it by 1.2 to 1.25. This extra space ensures your UPS works better and is more reliable.

• For a regular computer with one screen, it’s usually less than 300 VA. But to have enough time to turn it off safely, you’ll need a UPS with at least 650 VA.
• If you’re running a big data center with lots of servers, you’ll need a big UPS to keep everything running until the power comes back.
