Function
-Avr AS440 generator spare parts 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.
Specification
-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%.
Features
-De-rate by 12% if mounted in portrait orientation.
- With 4% engine governing.After 2 minutes.
-Generator de-rate may apply. Check with factory.
- Factory set, semi-sealed, jumper selectable.
-De-rate output current by 5% per degree C above 60C.
-Any device connected to the analogue input must be fully floating(galvanically isolated form ground), with an insulation material.
-Non condensing
