Universal Engine Spare Parts

Stamford avr AS440 is use for 50-500kw ,brushless diesel generatorcompatible with stamford products

Generator parts mainly include control box,fuel tank, start and control with battery protection, as well as emergency tank, etc

We supply:diesel controller,battery charger,voltage protector(AVR) and meters and other spare parts.

Description:In addition to rregulating the generator 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 generator.

Afrequency measuring circuit continually monitors the generator output and provides output under speed protection of the excitation system,by reducing the output voltage proportionally with speed below a pre-settable threshold.A manual adjustment is provide for factory setting of the under frequency roll off point,(UFRO).This can easilly be changed to 50 or 60Hz in the field by push on link selection.

Provision is made for the connection of a remote voltage trimmer,allowing the user fine control of generator's output.
