I have a APC Silcon 20KVA UPS which got hit by lightening. Now when the power is restored the fuses get burned. We found the PSU board to be defective. Can somebody tell me the dc output voltage from the PSU board.

Yes,

You can check PSU out put on Capasitors which install on output.
One of 470mf 25v and other 5 capasitor 1000mf 25v.
on all capasitors 13.3vdc and 5.4vdc will correct volts.

I have a 20kva UPS(APC),some time it is showing battery temperature exceeded upper limit


A termination voltage is a voltage that either indicates the charger should stop a phase or stop all charging. When batteries begin to wear out some or all of the cells can overheat when the charger attempts to bring them up to a termination voltage but cannot reach it efficiently, and thus heat (sometimes a lot) can be generated.

This is my first take on the problem. One should check if the battery is actually hot when the message says it is. If it's not then the problem is with the sensor or the software.

Silcon DP360, 3-phase 60kva, 400v, year 1993 1. Its old but working perfectly, after I changed the battery bank, because of collapsed cells, it still runs as expected but, I cant get any power readings...


#1. You should call APC Technical Support. It's free, and they will help you. You should get voltage even without a load on the unit.

#2. There is a Tripple-Slot unit for this device. It's specific for the Silcon based units. Read the manual, and there is a PN that you need for it. If it doesn't say SILCON, then it won't work. (I tried).
