Pete, The UPS has a rating on it related to the power it can supply when running on battery.
The rating is so much power for a certain amount of time. There are some UPSes that do power conditioning too, so there may be some limit to the amount of current it will pass under normal circumstances as well. If it is a "normal" UPS, you probably can plug two computers into it, and under power loss, your usable time will be reduced by some amount. If you exceed the maximum limits of the UPS you risk burning out some components. Also, it's a real good idea to test these things occasionally to be sure they work properly. I've seen them catch on fire during power failures. This is no joke. 73, Bob N5NJ ----- Original Message ----- From: "Pete Smith" <[EMAIL PROTECTED]> To: <dx4win@mailman.qth.net> Sent: Wednesday, April 24, 2002 1:59 AM Subject: [Dx4win] Power consumption of PCs > The PC on which I run DX4WIN has a 200 watt power supply, which I am > currently powering with a 300VA APC UPS.
