HGM4020DC genset controller is specially designed for mobile communication base station, and its functions are completely followed by the actual situation of the mobile station. It not only fits with auto start/stop genset function in multiple boot conditions, data measurement function, alarm protection function and etc, but also can control switches of 6 rectifiers at most and their parameters, at the same time it can monitor machine room temperature and voltage of battery packs to automatically start/stop genset and ensure normal working of base station.
HGM4020DC genset controller adopts micro-processor technology with precise parameters measuring, fixed value adjustment, time setting and set value adjusting functions and etc. All parameters can be configured from front panel or through programmable interface (USB or RS485 interface) via PC. It can be widely used in all types of automatic genset control system with compact structure, advanced circuits, simple connections and high reliability.
