Product Description
Brushless Alternator Automatic Excitation Regulator Board AVR EA125-8 is a half-wave phase control thyristor type automatic voltage regulator that is part of the excitation system of brushless generators. In addition to regulating the voltage of the generator, the AVR circuit has built in low speed and detection loss protection to ensure safe and reliable control of the generator. Positive voltage build up from residual level is guaranteed by using high performance semiconductor in the AVR power circuit. It is linked to the main stator winding and excitement porcelain field winding and provides the output voltage closed loop control with +/- 1.5% load regulation.
