Tips: Automatic AC voltage stabilizer wiring method

Fully automatic AC voltage stabilizer is divided into single-phase and three-phase stabilizers and their wiring method is very simple. For a 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 a 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 is 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.

How accurate the device is between phases?

How accurate the device is between phases? It would not work if I have 8 volt difference (Within range) but in one phase it is downwards and in another, it is upwards: 212V, 220V and 228V, since this It becomes a 16V difference between one phase and another.

Our stabilizer input voltage can not be a fixed value. For example: If the input voltages are 220V, 230V and 210V, these can not be a fixed value. Only the output can be a fixed value.

Would like to buy a automatic voltage stabilizer for my AC motor

We have a 100 hp AC motor and looking for a voltage stabilizer to be used, what will be recommended estabilizer power capacity of your brand? Does 150kVA automatic voltage stabilizer match it?

We recommend to use 200kVA voltage stabilizer (https://www.ato.com/200-kva-industrial-voltage-stabilizer), it will work effciently with such 100hp motor.
