Maxgeek EA04C Genset AVR Generator Automatic Voltage Regulator Single Three Phase Voltage Stabilizer Board

Maxgeek EA04C Genset AVR Generator Automatic Voltage Regulator Single Three Phase Voltage Stabilizer Board

Description:
Compatible single phase automatic voltage regulator AVR EA04C for diesel generator 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. Positive voltage build up from residual levels is ensured by the use of proficient semiconductors in the power circuitry of the AVR. Which is linked with the main stator windings and the exciter field windings to offer closed loop control of the output voltage with load regulations of +/-1.5%.
