Insulation resistance refers to electrical isolation extent between the internal of equipment or between the circuit and enclosure. View>>

The device combined by SCR, used to switch or for switching compensation. View>>

The parameters used to describe the average length of time when the equipment work normally: the greater the MTBF, the longer life of the device. View>>

It is a current protection device. When the current exceed the specifications ratings over the air switch, the switch will close. View>>

At boot instant the capacitor inside rectifier will inhale a great charge current. View>>

It refers to the highest voltage that live parts (such as housing, panel) can withstand. View>>

When you start UPS in the absence of electricity, some of them cannot boot, that is called cold boot. View>>

When the load mutate (0-100%, 100% -0), the time it takes for output voltage to restore to the specified scope, usually milliseconds (ms) level. View>>

A device used to eliminate noise interference, filtering the input or output to get the pure AC. View>>

Using physical principles to isolate and block electromagnetic radiation. View>>
