Post by thread:[EE:] APC 1000 Pro schematic

Last year I looked for a similar schematic but couldn't find it. APC support sucks. At the last resource I draw some parts of the schematic from the PCB and managed to repair the UPS myself.

I, too, would be interested in these schematics. I have a few APC's that have been sitting in a closet that I would like to repair. Do you have them on a web site; if not, could you send them by email? Thanks, Norris Lee McLaren wrote: {Quote hidden}>If you want I have .gifs of the Smartups and the Backups.

I salvaged an APC backup from a dumpster a few months ago, and the only thing wrong with it was that it needed a new battery. Though I would like the schematics in case it went bad. Can you post it somewhere? BTW: All of the APC backup models list their ability in terms of VA. I have no idea what this VA is supposed to mean (volt-amps maybe? I dunno, but wouldn't you normally call that WATTS?).

Me too! I have three of them which are dead.

Pico-tutorial on Watts, VA, reactive AC loads and power factor: > BTW: All of the APC backup models list their ability in terms of VA. I have > no idea what this VA is supposed to mean (volt-amps maybe? I dunno, but > wouldn't you normally call that WATTS?). Volts x Amps = Watts for a purely resistive load. If the load is partially reactive (either capacitive or inductive) as most real world loads are to varying extents, then the peak current and peak voltages do not occur at the same time. The current and voltage waveforms are 'out of phase" and V x A = VA is not equal to watts AND is greater than the Watts drawn by the load. In the limiting case, when the load is purely reactive, voltage and current waveforms are 90 degrees out of phase and there is NO power drawn even though voltage is present and current flows. The power supply is rated in terms of the current it can deliver and this is essentially the same regardless of whether the load uses the current to create power or merely circulates it in a reactance. So the power supply (here a backup unit) is rated in VA and its up to the user whether this is used to the full or not. Real world industrial loads are often inductive and :power factor correction" capacitors are often added to make the overall load more like a pure resistance. This is not getting something for nothing - the capacitors can be thought of as storing the reactive current from the inductors and delivering it when the resistive load requires it OR as nulling out the inductive effects (all the same, different metaphors). This problem is not limited to AC power supplies such as your inverter. AC power distribution systems have to account for the current flow and highly reactive loads require oversized generation and delivery systems (wires, transformers etc). Industrial users have to ensure their plants have a certain power factor (related to reactive component) and those failing to do so attract severe cost penalties from the power suppliers.

About VAs vs. Watts (a message I posted recently on another list): --- The power rating on most UPSs is in VA, not W, because the UPS has a limited capability to cope with high cos phi situations. So Adding up the Watts on the connected appliances may not be right, if they have high (and not compensating each other) cos phi values. Typical items that may upset your calculation are fluorescent lights (which have inductive lag from the ballast choke) and squirrel cage motor fans (which have inductive lag). Modern monitors and computer power supplies do not cause problems however, although they have a small capacitive lead. As an example: fluorescent light = 40W at cos phi = 0.8 will take 40W but 40/0.8 = 50VA. A 220V,50W fan with cos phi=0.6 will take 50/0.6 = 83VA. As you can see the VAs add up faster than the W's. You want to calculate the VAs to see if the UPS will carry the load. For most normal situations adding the Watts and leaving a generous safety margin (30% or so for 2-3 computers and 2-3 monitors) will be enough. For this consider the UPS power rating in VA, as being Watts. Peter -- http://www.piclist.com hint: The PICList is archived three different ways. See http://www.piclist.com/#archives for details.
