Product description:

SX440 self excited brushless type genset voltage regulator with sensing input from 90 to 520VAC is a compatible replacement for Newage Stamford SX440 regulator.

Main features:

1、Voltage regulation < ±1%.

2、Can be use in parallel operation.

3、Adjustable DIP, TRIM & DROOP function.

4、Under frequency roll Off protection.

5、Sensing voltage loss protection.

6、Under frequency LED indicator.

7、Soft start voltage ramping.

8、 the selling point : DROOP and machines, auxiliary input , over-excitation voltage protection.

AVR adjustment ( adjusted at the factory , the user only when necessary, adjusted as follows ) :

1、the output voltage of the voltage regulator such as inconsistent voltage adjustment potentiometer clockwise , the output voltage increases ; and vice versa .

2、the frequency setting of the engine speed adjusted 47HZ, UFRO potentiometer counterclockwise rotation , so that the indicator light-emitting diodes , can be transferred back to the engine speed .

3、overcurrent less excited at the rated power of the generator , the rotating field trip potentiometer counterclockwise , so that the indicator light-emitting diodes , and then rotated about 5 degrees to shun .
