How do I select the proper size unit?

September 7, 2014 0 Comments

Sizing a UPS for a PC or workstation can be simple. As with any electrical device, a computer has a rating plate that will give the power consumption, usually listed as “amps”.

A UPS is sized by VA, or Volt Amps. To determine the VA, multiply the amps by the 120 (volts) to determine the VA (Volts x Amps = VA). Be sure to allow for at least a 20% growth factor.

Configuring a larger UPS is more complex with many more variables such as interaction between devices, different voltages, growth planning, and distribution. Contact a power professional at CPT for assistance.
