UPS has constant voltage 142V~290V and power of 360W. What is the reason why two hosts are plugged in, one is not turned on, the other is turned on, and the computer is restarted after unplugging or power off? It's simple. When a small UPS switches between the mains supply and the battery, the interruption time is longer, generally more than 15ms, which is equivalent to the power supply flashing, and then the computer will restart. Explain that your UPS is a backup type with low accuracy. Probably a cheap imitation.

For large UPS, they are all online, and the switching time must be less than 10 millisecond. Usually, the switching time is 0 milliseconds. ..

Solution:

1. Replace UPS with high-quality UPS with shorter switching time. Try to use online UPS, and recommend Sander.

2. Replace the power supply of the computer. The filter capacitor in the computer power supply is too small. Under normal circumstances, when the mains supply is less than 20ms, the host computer should not be restarted. However, when the capacitance is small, the energy stored in it is not enough to maintain the host for 20 ms, and the host will restart.
