How do I calculate the number of UPS delay battery packs?
0.5KVA UPS is back-up, no external battery. The smallest on-line is 1K, no 0.5K.
The three Radix 100AH batteries are configured for 600W equipment (100AH x 3 X 12V) / 600W X 0.7 = 4.2H (hours).
UPS spare time calculation method: (single cell capacity X battery number X 12V battery voltage) / equipment power X 0.7 loss = extended time (hours).
