Description
SmartGen HGM4020N Controller – For Generator with Automatic Transfer (AMF)
Ideal for automating generator sets with network monitoring and remote start/stop.
Main characteristics:
AMF (Auto Mains Failure) controller: automatically starts and stops the generator upon detection of mains failure.
LCD display with backlight and wear-resistant buttons.
Multi-language interface: includes Spanish, English, Portuguese, French, Chinese, Russian, Turkish and Polish.
Monitoring and measurement of grid and generator electrical parameters.
Automatic transfer control between grid and generator.
Simple connections and compact structure.
CANBUS compatible (J1939 protocol) for communication with electronic motors.
Supports MODBUS communication via RS485 for remote control, remote measurement and remote communication functions.
Parameter settings from the front panel or via PC via USB or RS485 port.
Configurable transfer time: from 0 to 99.9 seconds (up to 99,900 milliseconds).
Recommended applications:
Automatic backup systems with generator.
Industrial, commercial or rural installations requiring autonomy and remote monitoring.
