Hi to all,
I have CyberPower Value 2200E-B UPS which is not bypassing AC input to load.
When connected and turned on to AC 230V it does not show any error, it passes self test and on display it's shown input & output voltage, batt capacity and load - everything as it should be. Problem is that there is no output voltage (0V!) on any socket (only when connected to AC 220V!) However, when switched to battery power (eg power failure) UPS works normally, it switches to battery and output voltage is stable 220V.
I've tested all relays and they are OK, (voltage on their coils are 0V when UPS is on AC power). Charging of the battery works.
Any ideas or schematic would be appreciated.
