4914090 speed control board EFC4914091 electronic governor Cummins generator palette

4914090/4914091- engine electronic speed controller with closed loop control, and can quickly respond to the load changes of - engine instantaneous control, engine speed, supporting EFC series electronic actuator and the corresponding magnetic speed sensor, the perfect control of CUMMINS engine.

4914090 suitable for the following 350KW generator with PT pump; 4914091 for 350KW-1000KW equipped with PT pump generator sets:The slow starting controller is an improved product of the speed control board of the original Cummins unit, and has increased the following new functions

1, increase the smooth slow start process control, this new function can be solved in the process of starting the engine by rapid gas caused by low temperature is not easy to start, black smoke, reduce the noise of engine start, speed up time can be in 0 seconds, 5 seconds, 10 seconds, 15 seconds, 20 seconds, 25 seconds. For 30 seconds, the advantages in using automatic generating unit is particularly prominent;

2, increasing the input and short circuit protection function, can have the effect of preventing EFC output short-circuit and ground problems;

3, the anti frequency interference circuit is added to make the control board work more stably.
