Products: 
     ESC5120 generator governor is a fully electronic closed-loop control of the design, it is for instantaneous load changes with fast and accurate response to control engine speed, when connected to the matching electronic actuators and magnetic speed sensor signal, to control a wide range of engines. It is designed to be highly reliable, can withstand all kinds of electromagnetic interference around the engine range. By design, it is easy to install and can be pre-adjustments, including adjusting the idle speed is adjustable and work, to assist for input multiple machines or special purpose machines, as well as to prevent reverse battery voltage, transient pulse voltage, short circuit actuator fault protection and safety in case of loss of speed or power of the sensor signal. 

Product performance and features: 
     1, all electronic closed-loop control of design; 
     2, easy to install and can be pre-adjusted; 
     3, adjust the idle speed is adjustable and work, to assist for input multiple machines or special purpose machines; 
     4, the actuator short circuit fault and security in case of loss of speed sensor signal or power supply, etc.; 
     5, for stand-alone and parallel operation of PID (proportional, integral, derivative) controllers; 
     6, with a steady tone idling and adjustable rate; 
     7, long closed, Cummins long can be closed for the controller;
