Who bought a computer, but in the case of uninterrupted power is always automatically shut down, and later heard that my family away from the transformer far, voltage instability, then I bought a regulator, but the effect is not very good, There is still a power outage, and some people say that to buy a power supply, I do not understand the function between the two and the difference, please master answer!
Only AC voltage regulator, if this is not, buy a UPS, open the computer when the inverter, do not open the time, the battery charge.
Adjust the power supply regulator than the amplitude of the regulator, adjust the voltage width than the width of the regulator, for example, the regulator can only be 200V voltage transferred to 220V, but the regulator can be 180V Voltage transferred to 220V, so the power supply is better, but relatively high prices. Or do not buy, too expensive, the family is not necessary, because after the power, can only be maintained for about 15 minutes, their own use, and no important things, afraid of a sudden power out of something important to save, UPS is a must Do not spend that money
Power supply regulator power supply stability is better for home use
Buy a mountain with a voltage regulator UPS can solve the problem. In the place where the voltage fluctuation is particularly applicable, when the line voltage is low to a certain extent will automatically turn to battery power. If you often power off for a long time, you can choose long-term UPS
