Product description:
The AS440 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. The Propose employs surface mount technology (SMT) for high integration of features in a minute footprint AVR.In order to ensure the stability of the product, all AVRs go through 24 hours of high temperature aging test before leaving the factory.
