Thyristor Power Controllers (SCR)

Thyristor (SCR) power controllers that adjust heater power in electric furnaces steplessly from the 4–20 mA or voltage signal of a PID controller. Compared with on/off contactor control they reduce temperature swings and extend heating element life.

• Single-Phase Thyristors – Autonics DPU1, 25 – 600 A, 220 V / 380 V
• Three-Phase Thyristors – Autonics DPU3, 25 – 600 A, 220 V / 380 V

Send us the total power, voltage and connection (star/delta) of the heater group and we will select the current rating and fuse together.

Send us your capacity, dimensions and process data and we will prepare an itemised technical offer. Use the Request a Quote button or call +90 533 945 27 94.
