Question about APC Smart-UPS 3000R3BX (SU3000R3BX135) UPS System

1 Answer

SMART UPS APC 3000

The APC Smart UPS 3000VA had dead batteries, and I replaced them with new ones. After replacing the batteries, I tested the unit with a 100W load (light bulb), and it switches to battery mode properly with cut AC. Once the load is increased to 300W (halogen bulb again) it reports low battery, even when the AC power is present. The unit properly switches to battery power on AC loss, but low battery is still on. Once the load is decreased, the low battery goes off instantly and it works normally. I checked the battery voltage and I found 26V (2X13V) with 300W load (or no load) and AC power, and 23.5V (2X11.75V) when operated on battery with cut AC and 300W load, which seems OK. This problem is equal to one previous one but another model wanted to know as it is the solution

    Batteries check good and are charged. When test or power goes off, the unit shuts down and doesn't restart until commercial power is restored

    New batteries, replaced fan. Unit works on batteries but when plugged into AC both online and on battery lights blink and now does not function at all.( No power output ). Unplug from wall, unit will work off batteries. Plug back in both lights blink and I hear a clicking sound from the unit and no power output.

Unplug your UPS from the wall. Disconnect the batteries. Push the on button. LED's may flash. This is how to reset the logic. Connect the batteries and plug back in. Everything should be reset.

Continous beeping and no led's are lit


Basically for SURT models it should have an internal fault if you get that kind of symptoms. One (1) diode is already opened which is always a problem of this APC SURT series. you need to open the unit and do further troubleshooting or send it to APC service center in you area or APC service partner. if it still under warranty you can call APC call center and get a replacement unit. you just need the exact model and Serial number of the unit.
