Q: in summer time, voltage is quite unstable, computer restarts frequently. I checked the minimum voltage is about 150V, after using family voltage stabilizer and Santek MT1000 UPS, the problem still exists. It would alarm once use UPS. After battery is out of use, computer would shut down again. How to solve the problem? Whether wide power could ease the situation like this?
A: UPS is mainly used to deal with the sudden power-off situation; of course, many UPS products have voltage stabilization function. Santek MT1000 input voltage range is from 162V to 286V, even there’s no power off, when voltage drops below 162V, it would switch to adverse status to use battery for power supply, which is the reason why UPS hasn’t taken effect. As for the traits of your family power network, you should choose the UPS with bigger input voltage range, but such kind of products usually is expensive. Wide power is proper to deal with continual low voltage power or big fluctuation situation, on the market, some products could even work under the environment below 100V. So it should be enough to solve the trouble you are facing now.
