Single phase power control unit : THV-A1 series

THV-A1 series

Single Phase Power Control Unit
(20 to 200 amps)
  • Control type selection
    (Phase-angle/continuous zero-cross/zero-cross)
  • Communication function
  • Detects heater break of non-linear load
  • Ramp-up, Ramp-down
  • Gradient setting
  • Output Limiter High and Low
  • Base-up Setting (output bias)
  • Output mode selection
    (proportional electric power/voltage/phase angle)
  • Digital input for Auto/manual
As the THV-A1 single phase power control unit can be used with control modes selectable from constant voltage, constant current and constant power, it can be used with such heaters as noble metals (Platinum and molybdenum), super Kanthal, and SiC (Silicon Carbide) that have changing resistance in accordance with temperature changes.
Optional features like heater break alarm and communication can improve system safety and establishment of a supervisory system.

THV series

Single Phase Power Control Unit ( 20 to 100 amps )
The THV operates at 100 up to 240V AC and automatically selects power supply frequency 50 or 60Hz. Three types of control modes are selectable: phase control, zero-cross control to suppress high frequency noise, or zero-cross control.
The THV series of 20A and 30A carries UL/CSA approvals. And over 45A of THV series carries cUL approvals. (After December, 2005 models)
