LCD display (with backlight), LED light indication, touch button operation. Silicone panel and buttons are used, which have strong ability to adapt to high and low temperature environments. The power supply range is wide DC (8~35) v, which can adapt to different starting battery voltage environments. Collect and display single-phase voltage, current, frequency, power, load percentage parameters of power generation. The control has 3 working modes: manual, automatic, stop. HGM1790N generator set controller is suitable for stand-alone automation and monitoring (it can also be used for water pump units). The controller can realize the manual start/stop of the unit, and can also automatically start/stop the generator through the remote start signal, monitor and protect the unit by collecting and analyzing data such as power generation voltage, current, water temperature, oil pressure, etc., and at the same time indicate Troubleshooting, convenient and fast maintenance. The controller adopts graphic liquid crystal display, and the operation is clear and intuitive with the touch of a button. The threshold value and delay adjustment function of parameters can be realized through the front panel or USB interface (communicating with PC software). A of temperature, pressure, and oil level sensors can be used directly, and the parameters can be customized; the temperature and pressure sensors can be used in parallel with the temperature and pressure alarms respectively, and a level of protection is added while providing analog values. 1 programmable input port, which can be set as digital input or liquid level sensor 2 relay fixed output ports (fuel output, start output) 3 programmable relay output ports, which can be set for public alarm output, preheat output or idle speed control output and other functions; Color: BlackMaterial: ABS Package Contents: 1x Generator Controller Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
