How Do You Size a Branded UPS?

In today's world, where virtually every business relies on mission-critical IT equipment and solutions, it's more important than ever to have an uninterruptible power supply (UPS) in place to protect your network and equipment in the event of an outage or power surge.

However, you need to know how to size the UPS in order to choose the most appropriate solution for your work environment. It is important to calculate the total load that the UPS system will have to handle in order to select a unit with the right VA value. For an accurate load calculation, determine the apparent and active power of your equipment and determine the UPS run time requirements.

Sizing the ups system - what you need to know

Most APC branded UPS solutions are designed to give you enough time to properly shut down equipment in the event of a power failure. Traditional solutions typically store energy in a battery that only comes on if there is a problem with the normal power supply. The amount of power your UPS can provide depends on its rated capacity. However, when sizing a UPS system, you need to consider more than just the power rating. The amount of equipment connected to the UPS called the "load", is more important.

A load of a single computer with a monitor is typically less than 300 VA, but you need a UPS with at least 650 VA to shut down the computer properly. If you're running a data center with hundreds or thousands of servers, you'll need a larger UPS system to keep it running until the normal power source returns. At the UPS Online Store, our systems range from 650 VA to 100,000 VA. We can also customize many of our solutions to meet your specific needs.

The easiest way to find out how to size your UPS is to call us. We can send a qualified technician to your home to determine your needs. If you would like to get advice on sizing your UPS system over the phone, we can give you detailed advice if you have the following information:

Visible power

This information is usually found on your equipment labels.

Active power

Again, you can find the active power rating of the unit on the label or in the accompanying information materials.

Overloads

When sizing your inverter, be aware that any voltage or current requirement that exceeds specifications can result in system failure.

UPS run time

Will your equipment need to run for ten minutes or 24 hours in the event of a power failure? Different industries have different requirements for UPS systems.
