Automatic Voltage Regulator SX460 For Generator

Features:
- SX460 is a half-wave phase-controlled thyristor type Automatic Voltage Regulator(AVR) and forms part of the exciation system for a brush-less generator.
- In addition to regulating the generator voltage,the AVR circuitry includes under-speed and sensing loss protection features.Excitation power is derived directly from the generator termainals.
- Positive voltage build up from residual levels is ensured by the use of effcient semiconductors in the power circuitry of the AVR.
- Provision is made for the connection of a remote voltage trimmer,allowing the user fine control of the generator’s output.
