Choosing Right UPS

This was originally posted on APC forums on 10/31/2008


Hi All,

Need your help on choosing suitable UPS.
Detail information as below:
Total load in Amp: 15 A
Voltage used: 3 phase, 415 V with apparent power =7.78 KVA.

Question is, how big UPS power do i need to backup my system for 1 hour with spare capacity=20%? Is there any formula to calculate UPS power rating and how to relate it with running time?? Appreciate if you all can provide calculation.

Thanks,
Zury

Hi there,

Sorry for late reply. UPS to be installed in Malaysia where basically we have two type of voltage that is 240V and three phase 415 V. UPS necessary to backup my company system, basically server and require at least one hour power back up in case power failure happen.

So far, we have no genset that why we need at least one hour power back up.

Best regards,
zury

If I may ask an initial question...in what country will this UPS be installed so we can narrow down available models?
