Description
The SmartGen HGM6120N is a full-featured AMF (Auto Mains Failure) controller for single-unit generator systems that require automatic switching between mains and generator power. It combines smart control, precision measurement, and fault protection to manage automatic start/stop operations, real-time monitoring, and ATS operation. The controller features a 132 × 64 backlit LCD with multilingual interface options and a rugged silicone keypad. It supports five digital inputs, three analog inputs, and up to six relay outputs, allowing for flexible configurations including preheat, idle, and emergency start.
Designed to monitor both mains and generator, the HGM6120N handles multi-phase AC systems (1P2W, 2P3W, 3P3W, and 3P4W) and supports voltage and frequency detection. It measures and displays key electrical parameters like voltage, current, frequency, and power, plus engine data such as temperature, oil pressure, fuel level, and more. It is powered from a wide DC input range (8–35 V), making it compatible with common battery systems. Configuration can be done via the front panel or USB. It also includes an event log, real-time clock, and maintenance timer. The unit operates reliably in harsh environments, with a temperature range from –25 °C to +70 °C, and comes in a robust ABS housing, mounted via clips.
