UPS power supply with the choice of the cable, wire diameter

Release date：2019-09-28 16:28 author：admin click：

How to calculate, choose UPS power distribution wire diameter, wire:

Input current = UPS power capacity of * * * overload capacity/efficiency of the power factor of the input voltage (lowest) / 3

Battery current = power factor * * UPS power capacity/efficiency (battery number * 10.8 (10.8 for low battery voltage))

Output current = / 220/3 UPS power capacity

According to the above formula to calculate the current, small and medium-sized UPS power supply wire, cable according to the 3 ~ 3.5 A/mm squared current density

The corresponding wire, cable; Large UPS power supply wire, cable according to the A / 2.5 mm on the current density of the squared of the wire and cable.

Note: involves engineers door switch on machine wire, cable according to the original factory is equipped with the line diameter, cables.
