Are there any difficulties in connecting a PSU with active PFC to a voltage stabilizer or UPS?

Question

Electronics

Welcome all! I used to come across information that some computer power supplies with active PFC have compatibility problems with voltage stabilizers and UPSs.
Specific task: I will assemble the system, the power supply will be with active PFC (most likely Zalman ZM500-TX 500W or a similar model), the system unit will be connected to the IPPON AVR-2000 voltage stabilizer.
Q: Will there be any compatibility issues?
And if someone has a link to a material where this topic is analyzed in detail, I beg you to share. Thanks in advance for any help!

Answer 1

There are no difficulties. But cheap UPSs have a meander at the output, and active PFC consumes a sinusoid. If the power of the UPS is back to back (in numbers) - it will consider this an overload. In general, there is only one subtlety - the UPS should be more powerful. I don’t remember the numbers, 1.5 or 2 times more than the actual load.
