YD923M series diesel engine electronic governor can accurately control the frequency of diesel generator set and ensure the stability of generator output voltage and frequency by controlling the original engine fuel system.

 

 

 

YD923M series diesel engine electronic governor is a kind of high-performance automatic control device, which uses mature classical control theory as control strategy and realizes constant speed control of internal combustion engine by circuit. Its compact structure, high control accuracy, reliable and stable work, can be used for various types of diesel generating set power station matching, is the realization of diesel generating set product mechatronics of the new generation of electronic control system. The whole system is flexible and convenient to operate and install. It can adjust and control the speed of diesel engine and limit the maximum oil quantity. It also has the functions of emergency shutdown, speed feedback failure protection and real-time display of the current speed. The non-contact angular displacement sensor is used in the actuator to ensure the safety and reliability of the whole engine performance.

 

 

 

The technical performance and quality requirements of this product conform to the IEC standards of the International Electrotechnical Commission and the relevant professional standards of China, and has passed the classification certification of China Classification Society.
