AC Voltage Stabilizer
AC voltage stabilizer is composed of a voltage regulator, control circuit, and servo motor. When the input voltage or load changes, the control circuit samples, compares, amplifies, and then drives the servo motor to rotate, changing the position of the voltage regulator's carbon brush. By automatically adjusting the turns ratio of the coil, the output voltage stability is maintained.
- Overvoltage Protection
When the output voltage exceeds 10% of the rated voltage, the output power will be cut off after a delay of 3-5 seconds.
- Short Circuit Protection
When the load equipment is short-circuited, the input power will be cut off.
- Overcurrent Protection
When the load exceeds the rated output current, the output power will be cut off.
- Phase Loss Protection
When any one of the three-phase powers in the input power grid is lost, the voltage stabilizer will automatically disconnect to protect the equipment.
