Nupart Carton and Red Capacity AVR SX440 + Free fast shipping
SX440,brushless type avr is a compatible replacement spare parts for Stamford Newage.
Description
In addition to regulating the alternator voltage,the avr circuitry includes under-speed and sensing loss protection features.Excitation power os derived directly from the generator terminals.
Positive voltage build up from residual level is ensured by the use of efficient semiconductors in the power circuitry of the avr/
The avr is linked with the main stator windings and the exciter field windings to provide closed loop control of the output voltage with load regulator of +/-1.0%.
In addition to being powered from the main stator,the avr also derives a sample voltage from the output windings for coltage control purposes.In response to this sample voltage,the avr controls the power fed to the exciter field,and hence the main field,to maintain the machine output voltage within the specified limits,compensating for load,speed,temperature and power factor of the Alternator.
