AVR SX460 Automatic Voltage Volt Regulator Replacement For Stamford Generator

AVR SX460 Automatic Voltage Volt Regulator Replacement For Stamford Generator

Description:
- 100% Brand New And High Quality
- SX460 is a half-wave phase-controlled thyristor type Automatic Voltage Regulator (AVR) and forms part of the excitation 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 terminals.
- 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.
