Powerful supervisor controller


Powerful supervisor controller for multiple parallel and multiple mains applications. Colour display 4.3’’ and PLC functions included.

Main features:

  • Controller for the management of Soft Load Transfer between Multiple Mains supplies and Multiple Gensets to avoid any break in supply to the load.
  • Management of the MCB (Mains Circuit Breaker) and MGCB (Master Genset Circuit Breaker).
  • Smart Load Management.
  • Import/Export power control.
  • Built in PLC functions.
  • Peak shaving and Peak Lopping functionality.
  • Centralized management of Base Load Reference.
  • Automatic Load shedding.
  • Full loss of mains Mains protections: ROCOF, Vector jump, Under and Over Voltage/Frequency.
  • Range of communication serial ports for the remote monitoring.



  • To handle multiple mains incomers (1 unit per incomer)
  • True RMS readings on bus and mains voltages and currents
  • MCB and MGCB synchroni­zation of multiple generators
  • 18+3 programmable digital input
  • 18 programmable digital output
  • RS232 interface port with Modbus RTU protocol
  • Additional RS232 or RS485 interface port
  • Real Time Clock
  • Events and data logging
  • GSM and PSTN modem management
  • SMS communication
  • Ethernet interface (optional)


  • HT-MC200 controller is an automatic control unit intended to safely manage the following type of power plants with and without MCB and MGCB management:
    – MPM (Multiple Prime Mover)
    – MSB (Multiple Stand-by)
    – MSB + MSTP (Multiple Stand-by + Multiple Short Time Parallel)
    – MPtM (Multiple Parallel to Mains)
    – MSB + MPtM (Multiple Stand-by + Multiple Parallel to Mains)
  • HT-MC100 can be combined with HUEGLI TECH controllers for paralleling/synchronizing applications, i.e. HT-DST4602, HT-DST4601/PX, and HT-GC500 communicating via PMCBus over CAN
  • A CAN cable is the only required connection to the controlled generators
