Full Featured, Microprocessor-Based,  for Motors 4-3500A, 4-3000KW, 208-1000V

 

  • Eliminates high inrush current and damaging mechanical shock
  • Third generation microprocessor circuitry
  • Heavy duty design: 50°C ambient temperature
  • Soft, stepless acceleration & deceleration
  • Power factor capacitors can be connected directly to the upstream contactor 
  • Unique starting & stopping characteristics
  • Sophisticated motor protection package
  • User friendly, easy installation and operation
  • RS485 Communication with MODBUS, PROFIBUS or MODBUS/TCP protocols (others available on request)
  • Wide 45-65Hz Auto-tracking frequency range combining special software with unique hardware arrangement allowing starting and stopping while the frequency variates (designed for Marine, Offshore and Generators operating under continuous frequency variation

    Advanced Starting and Stopping Characteristics

    • Reduced inrush current & mechanical shock
    • Soft, smooth stepless acceleration & deceleration
    • Unique features such as: Pump Control Program, Dual Adjustment, Slow Speed with Electronic Reversing, Energy Save, etc.
    • Torque and current starting & stopping characteristics

     

     

     

    Sophisticated Motor Protection

    • Too many starts & start inhibit.
    • Long start time (Stall protection)
    • Electronic shear-pin (Jam) with adjustable curves and delay
    • Electronic overload with selectable curves
    • Under current with programmable auto reset
    • Phase loss
    • Phase sequence and Under/Over frequency
    • Under/Over voltage with programmable auto reset
    • Load loss (broken drive belt)
    • External fault
    • Shorted SCR
    • Starter over temperature protection
    • Motor insulation test (option)
    • Motor thermistor (option)
    • When using "Preparation for Bypass" all protective functions remain active

     

    Control

    • All inputs & outputs are isolated.
    • Three C/O output relays.
    • Thermistor input.
    • Analogue output.
    • Communication RS 485 with MODBUS RTU or MODBUS Plus protocols.
    • User friendly keypad interface allowing precise settings.
    • Bright LEDs for immediate visual interface.
    • Interactive and informative 4 language LCD for easy trouble shooting.
    • Statistical data.
    • Motor insulation protection.
