The HGM4020DC generator set controller is a power generation control module developed for mobile communication base stations. The functions of the controller are completely set according to the actual situation of the mobile base station. The controller has the functions of automatic start/stop, data measurement, alarm protection and other functions of the generator set under multiple start-up conditions, and the controller can control the switch and parameter control of up to 6 rectifiers, and can monitor the temperature of the machine room and the voltage of the battery pack. To achieve the purpose of automatically starting and stopping the generator set and ensuring the normal operation of the base station.

The HGM4020DC generator set controller adopts microprocessor technology, which realizes the functions of precise measurement, constant value adjustment, timing, and threshold value adjustment of various parameters. All parameters of the controller can be adjusted from the front panel of the controller, or using a PC through the USB interface It can also be adjusted and monitored using a PC through the RS485 interface. It has compact structure, simple wiring and high reliability, and can be widely used in various types of generator set automation systems.
