Tpr-2p-380 Series Two-Phase Thyristor Power Regulator With Ingress Protection by Radix

Phase Angle and Cycle Control with Zero Crossover technology 30 Amps to 750 Amps current carrying capacity 1-phase / 2-phase / 3-phase versions Suitable for 3 phase star without neutral / closed delta configuration Provision for Auto / Manual operation Accepts 4~20 mA / 1~5 VDC / 0~5 VDC / 0~10 VDC / 2~10 VDC control input, pulse control input. Soft start for smooth control Adjustable power output - voltage / current control Isolated heat sink for safety with NTC Simple & modular design for easy servicing of cards & thyristors Ideally suitable for resistive, transformer, inductive or heating loads like Silicon Carbide & Molybdenum Disilicide which exhibit significant changes of resistance with increase in temperature LED indicators for status Cooling fan for temperature control which extends its life Relay output for remote supervision under following conditions : phase failure, fuse blown and heat sink over-temperature Ideal replacement for traditional mechanical contactor / relay accepting DC logic input signal
