I have two CyberPower 1500AVR UPSs that I use for computers.
I just hooked my aquarium equipment (2x Rena XP3) into one of the UPS and decided to do a power outage test and was very disappointed.

When I unplug the UPS power cord from the wall outlet it switched to a battery backup and both filters started making ‘scratching’ noise and the outflow was down to almost 0.

I tried the second CyberPower UPS – same results. I’m glad I tested this now…

Are CyberPower UPSs not good for this kind of application?

SOLVED: Rena XP3s are working fine with CyberPower PFC compatible Pure sine wave (PFCLCD) UPS!
