Uninteruptable Power Source Fuse trouble shoot,fuse location etc.
Re-test the battery under load to see if you still are able to get the
nominal 13V. Bob "BrianAlex" wrote in message ... On Jan 5, 2:57 pm, Ronbo wrote: BrianAlex wrote: Hi. I have a UPS that is not functioning correctly. It's an APC "Professional Powercell" 250 watt unit that is at least 5 years old. When there is a power outage, it beeps loudly but there is no current to the outlets (computer is plugged to this). I took out the 12 v lead battery and it tests 13 volts. I pushed the "re-set" button. I dismantled the case ("no user serviceable parts) and there is a note to use only the same size fuse. Well there is no indication where the fuse is,and I believe this may be the problem since at one time I had too much stuff plugged in (not being aware of it's 250 W limit). There is an orangish part that looks like a plastic plug-in automobile fuse that says"40" on top and on the solder side says "40A 32V". I checked from this side and it has continuity,plus the element in it appears solid. Would there be a fuse somewhere else? I don't see one. Also I see a "APCC (C) 1993" on the board so maybe this thing is that old. What else would cause this failure? I consider this a learning opportunity,and I am a cheap so-and-so and will not be paying the big bucks for a new one any time soon! Your advice greatly appreciated.-Brian That is the fuse but there is probably also a circuit breaker on the back panel. If tripped a small blade will pop out. What model is it?- Hide quoted text - - Show quoted text - The model is; "Professional Powercell" s/n; C94093679593 and yes, it has the little blade that says "push,reset" around it (which I did). Maybe this thing is toast,but I don't quit on stuff very easily. Thx. BrianA |
