I have Mustek PowerMust 1000 UPS. After recharging its battery, it stars emitting some strange sound. Is this behavior is normal or there is some problem with the UPS. Please help.
Welcome to clubCDfreaks SasoM,
Is the UPS brand new? if it is then definitly return it. Chances are the noise is from one of the transformers inside. It might go away after the battery is fully charged, definitly within a day. Some noise from the transformer doesn’t mean it not going to work or catch fire, its just a poorly manufactured transformer.
Thanks for the quick answer.
I have 2 UPS’s and never heard anything out of them like that. I they did i would take them back. I value my pc’s to much for that crap.
Thanks for you confirmation.
