KVA

I'm guessing that you are talking about power supplies and UPS's, etc and are wondering about how to size your power suppply system for your computers, etc. - If you are talking about something else, please accept my apolgies.

KVA stands for KiloVolt Ampere. And you now know nothing more than you did a moment ago :-) Basically, 1 Volt Ampere (1VA) is roughly equivalent to 1 watt, therefore 1 KVA is equivalent to 1000 Watts or 1 KW.

What does all this mean? Each piece of equipment you own will have a power rating on it. For example, a computer may have a power supply rated at 250 watts, a monitor may have a rating of 200 or 300 watts, depending on its size. You will find either that number stamped on the nameplate, or more frequently, you will see somthing like 120VAC - 2.5Amps. In the second case you would multiply voltage times current to get power (eg: 120 x 2.5 = 300Watts, or roughly 0.3 KVA).

Hope this helps
