Product description:

SX440 is a half-wave phase-controlled thyristor type Automatic Voltage Regulator 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.It contains British WELLWIN glass glaze resistance which can works at high temperatures over 200℃.this is the reason to make sure our AVR can works at high temperature environment.As a classic AVR model, it is widely used in generator assembly plants and generator repair departments.

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 .
