Question about Belkin (F6C550-AVR) (DBF6C550AVR) UPS System

1 Answer

For a Belkin F6C550-AVR: (1) House

For a Belkin F6C550-AVR: (1) House experienced a recent power failure. (2) Surge-protected only outlets are live (120V). Battery backup outlets are not (0V). (3) None of the front panel LED's turn on. Holding On/Off/Test switch down results in a single beep about every 2 seconds, even when unit is NOT plugged in. (4) A slight click is audible each time unit is plugged in. (5) Multimeter shows battery at about 6V. (6) Pressing the circuit breaker on the rear panel has no effect. Is there an internal fuse that might have blown? Are there any other ways to test the system, e.g. with a multimeter, other than buy a new battery and hope that was the problem?

Moss Fet Transistors Failure.
When an UPS works too Much time power line disconnect always the UPS only works for a while. too much time working with the Batteries inside makes the power converting transistors overheating and failure.

Check Internal Fuses, inside the UPs there is an automotive Fuses(30 Amps) plug tipe like in cars.

if the fuses are OK .........................then check it by a Technician.

Check it by a Qualified Technician and check the Mossfets.

How do I know when I need to replace the battery

The only thing you will look out for is the specs of the battery. That is the voltage that it gives out. The size usually determines the hours it can provide power on a full charge.

Belkin f6c750-avr repair / Testing

You could be correct on the transformer. I'm kinda leaning towards a bad cell in the battery. Sounds like it will need replacing.

UPS periodically disconnects

You have a smart chip problem. Your unit is too small that would be cost effective to repair.

check out my web page:

I will help you save a few dollars but I think you might need a little bigger UPS then a 550. Try going bigger.

The AVR-3300 power-off to stand-by mode

You have a blown amp or a leaky cap and the unit is going in to save mode to avoid destrying the unit.

Take it in for a repair. I don't think it should run more than $50-$75 for a fix depending on what component is bad.
