AC Brushless Alternator Easy Spare Parts Generator Automatic Voltage Regulator Circuit Diagram AVR AS440

Product Description

AS440 is a half-wave phase-controlled thyristor type AVR and forms part of the excitation system for a brushless generator. The design employs Surface Mount Technology (SMT) for high integration of features in a small footprint AVR. Positive voltage builds up from residual levels is ensured by the use of efficient semiconductors in the power circuitry of the AVR. The power and voltage sensing circuits have separate terminals, allowing the excitation power to be derived directly from the stator winding for basic applications or from an auxiliary winding if sustained short circuit performance is required.
AVR AS440 adjustable alternator voltage regulator 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 builds 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%

* Voltage regulation < +/-1%
* Soft start voltage ramping
* Sensing voltage loss protection
* 120 or 240 Vac sensing, jumper selectable
* Under frequency roll-off protection
* With under frequency LED indicator
