Features 1、CONTROLLER STRUCTURE: The generator controller is modular design, with pluggable terminal blocks, embedded installation, patterned LCD display (with backlight), LED indicator light, touch button operation, with silicone panel and buttons. 2、WORKING RANGE: The controller power supply range is DC8‑35V, which can adapt to different starting battery voltage environments, with manual, automatic, and shutdown working modes, with unit fault protection and display functions. 3、PARAMETER DISPLAY: Collect and display single phase voltage, current, frequency, power, and load percentage parameters for power generation, with customizable parameters and multiple starting conditions (speed, oil pressure, power generation frequency) to choose from. 4、INPUT OUTPUT PORTS: With 1 programmable input port, can be set as a switch input or liquid level sensor, 2 relay fixed output ports (fuel output, start output), 3 programmable relay output ports, can be set with public alarm output, preheating output, or idle control output, etc. 5、PARAMETER CHANGE: Allow users to change and set their parameters, which will not be lost in the event of system power failure. Most parameters can be adjusted from the front panel of the controller, and all parameters can be adjusted using a PC through a USB interface. Specification Item Type: Generator Auto Controller Model: HGM1790N (GC1790N) Display: LCD (with backlight) Operation Panel: Silicone Controller Language: English Digital Input: 1 Relay Output: 5 Analog Input: 1 AC System: 1P 2W Generator Voltage: 15-360Vph-N Alternator Frequency: 50/60Hz Programmable Interface: USB DC Power Supply: DC8-35V Speed Sensor Voltage: 1V-24V (RMS) Speed Sensor Frequency: 10000Hz CT Secondary Rated Current: 5A Shell Size: Approx. 95 x 86 x 46.5mm / 3.7 x 3.4 x 1.8in Panel Opening: Approx. 78 x 66mm / 3.1 x 2.6in Working Temperature: -25-70℃ Product Introduction: The generator set controller is suitable for single machine automation and monitoring control (also applicable to pimp units). It can be started and stopped manually or through remote start and stop signals. The controller monitors and protects the operation of the generator set by collecting and analyzing data such as generation voltage, current, water temperature, and oil pressure. The front panel graphical LCD display displays the fault status and provides effective alarm signals, facilitating maintenance as soon as possible. In addition, parameter thresholds and delay values can be adjusted through the front panel or USB port (communicating with PC software). Package List 1 x Controller 2 x Mounting Screws 1 x User Manual
