Autonics DPU12B-120N is a single-phase, 220 VAC, 120 A digital thyristor power controller from the DPU series. It adjusts electric furnace heater power steplessly from a 4–20 mA / 0–10 V PID signal. At rated current on a 220 V single-phase supply it corresponds theoretically to approx. 26.4 kW of resistive load.
