EasyLogic APF with UPS

[AlanK]

Hello everyone,

A customer needs to compensate load harmonics downstream of a UPS.

Can I install an EasyLogic APF downstream of a UPS? (see attached diagram)

What do I need to keep in mind in order to implement this solution?

Regards

Hello Alan,

Generally, EZAPF can apply on this UPS scenario, but need to take care below aspects:

• UPS output voltage range if in work scope of EZAPF
• EZAPF capacity if enough for application
• load if change too fast
• checking waveform of load if there are notches, if consider install reactors
• checking frequency range

We suggest you to contact with your local competency team for a checking list.

Best Regards
