I want to buy new UPS a branded one (500VA or 650VA) but i am confused which one to buy. looked through various brands on the internet such as powersafe, APC. The UPS should have a good voltage management system and i mean really good. my old UPS automatically shifts to Backup mode whenever there is a high or low voltage problem and it does not come back to normal mode, though it should. help me with new UPS
