Which UPS should I choose for my equipments?
Firstly of all, you should make sure the power of your devices. Generally, the power of PC and IPC is 200w, and the power of MAC is about 300W. Secondly, you should know the rated capacity of UPS. There are two ways to express rated capacity: apparent power (VA) and the actual output power (W). Conversion relationship between them is that apparent power multiply power factor is equal to actual output power. The power factor of Line-Interactive UPS and backup UPS is about 0.5 to o.7, and on-line UPS is about 0.8.
