Product Overview:
HGM8156 Genset Busbar Parallel (with Mains) Controller is especially designed for extremely high/low temperature environment (-40~+70)°C. It applies self-luminous Vacuum Fluorescent Display (VFD) and electronic components with extreme high/low temperature resistance, therefore it can work reliably under extreme temperature conditions. After careful consideration for the electromagnetic compatibility on different occasions in designing process, it provides strong guarantee for it to work under complex electromagnetic interference environment. It is plug-in wiring terminal structure, which is convenient for product maintenance and upgrade. Chinese, English, and other various languages can be displayed on controller.

HGM8156 Genset Busbar Parallel (with Mains) Controller suits the manual/auto parallel system of multiple gensets with single or multi-channel mains, realizing auto start/stop parallel operation of multiple gensets. Graphic display is applied. Operation is simple, and working is reliable. There are also multiple options that can be selected of parallel running mode with mains, for example: constant active power and reactive power/power factor mode of genset output; mains peak clipping mode; constant power mode outputted to mains; load taking mode; incessant recovering to mains supply function. It employs 32-bit micro-processor technology, realizing functions of precise measuring for most parameters, set value adjustment, timing and fixed value adjustment etc. Most parameters can be regulated from front panel, and all parameters can be adjusted via USB on PC. And parameters can also be regulated and monitored via RS485 or Ethernet on PC. It can be used widely in various genset automatic parallel systems.


With ARM-based 32-bit SCM, it has high hardware integration, and reliability is promoted to a great degree.

Graphic dot-matrix VFD, Chinese/English are optional, and can be selected on site, which provides convenience for debugging persons.

Acrylic material of hard screen for protection, with better wear resisting and scratch resistant performance;

Silicon panel and button, which makes it have stronger adaptability for high/low environment;

RS485 communication port, which can realize "three remotes" function with ModBus protocol;

Ethernet communication port, realizing Ethernet monitoring (it needs to use controller with Ethernet port);

Suitable for (120/240V) power, 50/60Hz system of 3-phase 4-wire, 3-phase 3-wire, single phase 2-wire, 2-phase 3 wire;

Collect and display 3-phase voltage, A-phase current, frequency, and power factor of busbar;

Collect and display 3-phase voltage, 3-phase current, frequency, and power factor of mains;

Complete mains parallel off protection function, over frequency, under frequency, over voltage, under voltage, frequency change ratio, vector change;

Synchronizing parameters are: voltage difference between busbar and mains, frequency difference between busbar and mains, phase angle difference between busbar and mains;

Multiple working modes in auto status: auto start at mains inactive, island running, input/output constant power, peak clipping mode, load taking mode;

Soft load shift function at parallel and parallel off;

Control protection function: realizes diesel genset auto start/stop, breaker close/open, and thorough fault display protection functions;

All outputs are relay outputs;

Parameter setting function: allows users to change and set parameters, and this will be restored in internal FLASH memory, and will not lose at power outage. A majority of parameters can be adjusted on front panel, and all parameters can be regulated by USB port on PC, or by RS485/Ethernet port on PC;

Power supply range DC(8~35)V, which can suit different starter battery voltage environment;

Event Log, Real Time Clock, Scheduled Start/Stop (once per month/week/day, and loading or not can also be set) functions;

Can be used as indicating instrument (only indication, alarm and relay doesn't act);

Maintenance function, maintenance time due actions can be set;

All parameters are adjusted by digitalization, getting rid of analog adjustment of traditional potentiometer, improving reliability and stability of whole controller;

Sealing gasket is designed between enclosure and panel window; waterproof level is IP55;

Metal clips are used to fix the controller, which has outstanding performance in high temperature;

Modular structure design, pluggable wiring terminal, build-in installation with compact structure and easy mounting features;
