Autonics DPU digital thyristor (SCR) power controller, three-phase version. In electric furnaces and melting furnaces it adjusts heater power steplessly according to the PID controller signal, giving more precise temperature and longer heater life than contactor switching. This is the series we prefer in our own resistance furnace panels.
