Product Description:

The ESC5522 series speed control unit is an all electronic device designed to control engine speed with fast and precise response transient load changes.  

The ESD5522E /5525Series speed control unit is an all electronic device designed to control engine speed with fast and precise response transient load changes.   (ESC5520E is designed for CUMMINS EFC series.) 

Isochronous Operation/Steady Stability---- +/-0.25%

 or better Supply----12 or 24 VDC Battery Systems(transient&reverse voltage protected) 

Power Consumption----50 ma continuous plus acutator current 

Maximum Actuator Current at 25celsius (77celsius F)----10 Amps continuous 

Main features:

1、 the whole design of the closed loop control;

2、 installation is simple and can be adjusted in advance;

3、 work rate and idle speed is adjustable, to help is used for more than one machine or special purpose machine input;

4、 the actuator fault and in the case of losing speed sensor signals or power supply safety protection, etc.;

5、 start with a smooth speed control board (SMD components);

6、 increases the overspeed protection, than the average speed control board + overspeed protection board more reliable、 safe.
