Stamford Generator Spare Parts AVR AS440 With Nupart Package


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

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


Description:


In addition to regulating 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.

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