SE350 universal ac regulator avr is a half-wave phase controlled thyristor type Automatic Voltage Regulator and forms part of the excitation system for a brushless generator. In addition to regulating the generator voltage, the AVR circuitry includes under speed and sensing loss protection to ensure safe, reliable control of the generator.

Features:
1. Voltage regulation <±1%.
2. Soft start voltage ramping.
3. Sensing voltage loss protection.
4. 120 or 240 Vac sensing,jumper selectable.
5. Under frequency roll off protection.
6. With under frequency LED indicator.
