Product overview

 

 

 

YD911 diesel generator control box is a single-chip microcomputer-controlled automatic detection and overstepping alarm protection device for diesel engine operating conditions. It can automatically measure the rotational speed, cooling water temperature, oil temperature and pressure of various high and low speed diesel engines. It has digital display, multi-parameter monitoring alarm and overstepping protection, and sends out acousto-optic report. The alarm signal can automatically control the emergency shutdown of diesel engine, and can measure and display the power supply voltage, generator voltage, frequency and load current. The instruction manual is matched with the schematic diagram of figure No. SYF4.021.177.
