Tips: Automatic AC voltage stabilizer wiring method

Fully automatic AC voltage stabilizer is divided into single-phase and three-phase stabilizer and their wiring method is very simple. For single-phase voltage stabilizer, there are two lines at the output, zero line and live line. We just need to connect the zero line and the live line at the input end to the main power supply, the zero line and the fire line at the output end to the required equipment, and then connect the ground line.

For three-phase voltage stabilizer, the output voltage is three-phase 380v, three-phase four-wire system, which means that there are three live wires and one neutral wire. We should note that the three-phase voltage stabilizer is phase sequence protected. The phase sequence must not be mistaken when wiring. The input end of the voltage stabilizer is connected to the main power supply, and the output of that connected to the device. Observe whether the input voltage and output voltage of the regulated power supply are stable. If the output is stable and there is no abnormality, then the three-phase voltage stabilizer can be used.
