Stamford AVR Sx460 (Automatical voltage regulator)

Basic Info

Model No.:  SX460

Product Description

Model NO.: SX460 Usage: Emergency Crew, Standby Unit, Common Units Cooling
Method: Air Cooled Generator
Type: diesel generator Transport Package: Carton HS Code: 8503009090 Conditions
of Use: Car Type, Trailer Type, Marine, Land Use Output Type: AC Three Phase Installation
Method: Fixed Trademark: STAMFORD Origin: China SX460 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%
