GE LP33 UPS inverter failed to start

Dear Yared,

Did you try to give the UPS some time to recharge the batteries?
Seems like the batteries have reached their cut-off voltage and are not supplying enough voltage to the inverter.

Normally the dc boos circuit of the UPS will supply voltage to the DC BUS so maybe the problem can be found in the dc boost circuit or BUS if recharging the batteries is not helping.

Let me know.

Best Regards,

Hi, I have an Opti-UPS ES 1000C. When power goes off, it beeps and shuts down. Everything plugged into it shuts off. It does not convert to battery power. What's wrong?

The Batteries are bad. It can't convert to battery because the batteries are bad. Plug the UPS back in then pull the plug. If if goes off the batteries are bad

Constantly running on battery mode even with a proper electrical supply and shutting down to recharge

try to reset the circuit breaker switch, and check the ac cord if it has no cut or loose in plug.

Need information

The Back-UPS is fairly straight-forward. The 9-pin connector (at the top of the back) is a serial port (RS-232) for the UPS data (when connected to a computer it will shut down the computer safely during a power outage). The next plugs are RJ-11 telephone jacks; the cord from the jack (wall) goes in on the left (some models have RJ-45 for network protection). The battery protected outlets are the three surrounded by black paint. The other three provide surge-protection only. Do not plug items like printers and scanners into the outlets that provide battery protection.

I hope this helps.

Brand new apc 900 ups and when plugged in it after a while will beep loudly & overload button will flash..

I bought an APC 900XS UPS for $10.00. at a garage sale. I know you’re going to tell me that you take a gamble at a garage sale whether it works or not.
Please do not try to fix the device unless you are qualified electronic technician. There is high voltage and high current that is very deadly.
Before plugging the UPS in I opened the battery compartment and found the positive lead off of the battery. Took the batteries out and measured the voltage on both batteries and I couldn’t believe it, they were both good. Well at least they measured the right voltage. There are two batteries, each one is 12vdc. The real test would be to put the batteries under a load.
I plugged it in and ran for about six hours than the "Overload" LED and alarm turned on. I didn't have anything plugged into it "AC". When I first plugged it in, in the beginning I noticed the fan was running by the sound of it. But later that evening about an hour after plugging it in the fan was off. Don’t know why unless there is a temperature monitoring circuit on that heat sink and the fan wasn’t needed? After opening the unit I found a component unsoldered at one end. It looks like a capacitor or a spark gap component across the AC line. I don’t think that’s original problem. Re-soldered the component back in place. Took the board completely out and unplugged all the connectors. Again, after talking the PCB out. I didn’t see anything damage / burned. Without a schematic diagram one really can’t troubleshoot. I did noticed that (small) fan was kind-a hard to move by hand. I applied an external 24 volts to the fan. It was almost drawing 0.120 amps. The fan is rated at 0.070 amps. Took the fan apart and applied Tri-Flow (oil) to both bearings. Now the current draw has lowered. I’m wondering if the PCB has a current monitor of the fan driver, if the fan is/or requiring too much current that the unit shuts down. That heat sink that the fan is on seems to not dissipate very much heat, if any. It seems the fan is an over kill. There is a temperatures sensor mounted to the heat sink, probably to monitor the temperature of the heat sink in case the fan stops. Temporally connected everything back together. Now it’s running fine, but time will tell whether it’s going to stay running. After running four hours without any alarms, I re-assembled the unit. It’s been two days and the fan is still running and without any alarms. I haven’t plugged the computer into it yet.

Computer resets with Power cuts not always although UPS supplied

ups may not be true on line, type so sometimes when power outage happens there can be a very small break in supply. this can cause load items to shut down
get good quality on line ups.

you can program your power bottom to hibernate, and connect the screen direct without the UPS, so you get more time...then when the electricity goes off, without seeing the screen just push the power bottom to hibernate.
