6. Features of HGM6110N Generator Smart Controller
The HGM6110N Generator Smart Controller adopts a high-performance computer chip, allowing modification of the generator's control program and protection parameters. It integrates multiple functions such as measurement, control, protection, and remote monitoring (telemetry, remote signaling, remote control), fully meeting the automatic control needs of generator users or professional assembly plants for different types of generator sets.
- The controller measures and displays all electrical parameters of the generator output, as well as the engine's speed, oil pressure, water temperature, DC power supply voltage, and operating time.
- True RMS measurement is used for voltage and current to ensure more accurate data.
- Chinese/English menu selection and large-screen LCD display are available.
- The buttons on the controller panel are used to select the control mode, start-up and operation procedures, data display, and modification of operation protection parameters.
- LED indicators are used to indicate the controller's operation mode and the generator set's operating status, while the LCD displays various measured parameters and statuses.
- An optional RS485 or RS232 communication port is available to realize remote monitoring or communication with a PC, fully achieving telemetry, remote signaling, and remote control functions, and enabling reading and setting of the controller's operating parameters.
- The controller is composed of an aluminum alloy panel and a powder-coated steel housing, closely combined.
- All wiring of the controller is connected through pin-type locked terminals, making wiring, movement, maintenance, and replacement of the equipment very easy and convenient.
