THV-A1 SCR Power Controllers
Features 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
