General description SX460 is a half-wave phase-controlled thyristor type Automatic Voltage Regulator (AVR) that is an essential component of the excitation system for brush-less generators. It regulates the generator voltage and includes under-speed and sensing loss protection features. The excitation power is derived directly from the generator terminals, ensuring positive voltage buildup from residual levels through the use of efficient semiconductors in the power circuitry. Technical specifications Type: Half-wave phase-controlled thyristor AVR Color: Black Material: Plastic Measurement allowed error: +/- 1-3 cm Compatibility and accessories Includes: 1 x Automatic Voltage Regulator 1 x English manual Provision for remote voltage trimmer connection
