PERFORMANCE AND CHARACTERS
——
Graphic LCD display (backlight), LED indicators, push-button operation;
——
Acrylic material for hard screen protection;
——
Wide power supply range DC (8-35)V, which can suits different environments of starter battery
voltages;
——
Collect and display mains/gen 3-phase voltage, 3-phase current, frequency, and power
parameters;
Mains
Gen
Line voltage (L12, L23, L31) Line voltage (L12, L23, L31)
Phase voltage (L1, L2, L3) Phase voltage (L1, L2, L3)
Frequency (Hz) Frequency (Hz)
Load
Current (Ia, Ib, Ic) Unit: A
Total active power P Unit: kW
——
Mains has over volt, under volt, over frequency, under frequency, and loss of phase functions;
Gen has over volt, under volt, over frequency, under frequency, over current, over power, and
loss of phase functions;
——
Precisely measure all parameter values of engines:
Temperature °C Fuel level %
Battery voltage V Accumulated running time H (max. 9999 hours)
Speed RPM Accumulated start times (max. 90000000 times, display only on PC software)
——
Genset fault protection and display function;
——
Controller has 4 working modes: manual, auto, stop, and test mode, and MGC310 has stop,
manual, auto modes, and MGC320 has manual, auto, stop, and test mode;
——
Parameter setting function: allows users to change and set the parameters, which won't be lost
on system power off; a majority of parameters can be adjusted from front panel, and all
parameters can be configured by RS485 on PC;
——
1 programmable input port, 2 fixed input ports;
——
2 fixed relay output ports (fuel output, start output);
——
2 programmable relay output ports;
——
All parameters are adjusted digitally, improving the whole case's reliability and stability;
——
Sealing gasket is designed between the closure and the control window, whose dustproof and
waterproof performance can be reached to IP65;
——
Metal fixing clips are used to stable the controller;
——
Modular structure design, pluggable wiring terminal, and built-in installation, make it compact in
structure and easy to install.
