Can I connect a power supply with active PFC function to PowerWalker UPS?

Last Updated 7 years ago
Yes. Active PFC switching power will generate a peak in-rush current when it is switch on. For Offline and Line-Interactive UPSs with transformer inside it is unaffordable to back-up such inrush current. Then, the UPS will go to fault mode and shutdown immediately. But Online models can work with Active PFC due to differnt hardware design.
