THV-40 series

The THV-40 series are very rugged and reliable universal  1 phase thyristor units.

  • load type 1  phase resistive and transformer primary side
  • maximum load current: 20-200A
  • maximum load voltage: 380-480Vac
  • firing modes:
    • phase angle (for resistive and transformer primary side)
    • zero crossing on/off (for resistive loads only)
    • soft start/soft off on all modes
  • control modes:
    • proportional phase angle (open loop)
    • voltage
    • voltage square (V2)
  • Inputs:
    • 4-20mA
    • 1-5Vdc
    • 0-10Vdc
    • SSR logic signal (voltage pulse signal 12Vdc)
  • very easy configuration with USB interface, COM-KG interface and free software
  • optional
    • constant current control mode
    • external fuses and fuseholder
    • current limit
    • heater break alarm + SCR short circuit
