Autonics DPU33A-025N is a three-phase, 380 VAC, 25 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 380 V three-phase supply it corresponds theoretically to approx. 16.5 kW of resistive load.
