Re: the AC output power id to low, like 96VAC ; its bad...
Very bad!. Trash this and get a UPS with AVR technology and line interactive. 96V will burn up your power supply and this junk has no AVR technology that will help step it up. Also your load may cause a serious voltage drop, that means your UPS is way too small as it is. I suggest you think about going to a 1000VA or higher.
www.storminprotection.com. look on my web site, and check out the UPS's and I would be happy to sell it to you at my dealer cost to solve your problem.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.

check ac in inside UPS does it get converted to DC voltage inside UPS to charge the batteries. My guess of possible cause is Fault Capacitors on DC that filter the DC or a faulty power diode of a wheatstone bridge that is causing only half the AC cycle to be turned into DC. Check the power to the internal batteries is steady DC . Good luck in your troubleshooting
What is the sound? Is the device working normally? Are there any lights or indicators? Do they indicate a fault or error?
A UPS runs on standard 110-120 VAC power. It converts the input power to DC and charges internal batteries, then back to AC. Connected devices actually run on the conditioned 115-120 VAC output. The batteries serve as a short term backup power source.
The electronics in the UPS can produce hum or high pitched tones. The sound should not be annoying. If it is louder than connected equipment (computers) it may indicate a problem. Hum is usually 60 Hz harmonics and difficult to eliminate. This harmonic may be transferred to audio equipment such as speakers or radios. A high pitched tone can be related to the rectifiers for the convertor/invertor. If the tone is loud, it means the rectifiers are drawing a lot of current. This is usually related to bad batteries.
Measure the voltage on the output receptacles. It should be 115-120 VAC. Disconnect everything on the output receptacles. Unplug the UPS from it's power source. If the output power dies within 1 minute, the batteries need to be replaced.
is that 165 Volts AC or DC? Try to reset the logic. Unplug the UPS from the wall and disconnect the batteries. Push the "On Button" The LED's may flash. This is resetting the logic. This migh help. This should be 120VAC in and 120VAC out. Please give me an update.

No, I don't think there is anything wrong. Your UPS seems to have a single phase 240V output, which seems to be "floating" (no or only a weak ground reference). Just be aware that you can only power 240V equipment from it. If you need 120V for some devices _and_ if the UPS provides sine wave output, you could use a step down transformer for this purpose.
This is normal in some lower end UPS's, the voltage can swing quite a bit, a drop of 40 seems like quite a bit but it's out of the question. It will also adapt to what is plugged in yes. Ultimately to test you would want to try it with something like an actual PC plugged in and make sure it stays running. I'd say otherwise it sounds normal to me.
Hello Dear Specialists I have a problem with the APC Smart-UPS smart 1000VA: when I insert the power plug in the wall outlet in one ups , indicate the AVR Boost ups regulating low AC voltage, when I measuring the AC city power voltage that is 207v .whey this ups is not working about the AC low voltage? ,but it should be work from (170v ~ 230v) AC input volte.please solve this problem, which element of AVR from the ups is failed or wrong and give me free circuit diagram low & high AVR and charger and inverter circuits. thanks allot
