Product Overview:

The HGM4000N Series Genset Controller integrates digital control, intelligent processing, and network communication technologies. Designed for single-unit generator automation, it supports automatic start/stop, real-time data acquisition, alarm protection, and remote management.

Featuring a backlit LCD and multilingual interface (Chinese, English, Spanish, Russian, Turkish, French, Portuguese, Polish), the controller offers intuitive operation and high adaptability. Built on microprocessor architecture, it ensures precise parameter measurement, configurable setpoints, and time scheduling. All settings can be adjusted via the front panel or through USB/RS485 interface using a PC.

Its compact design, advanced circuitry, and simplified wiring make it suitable for a wide range of automatic genset control applications.
