3023 is available as a Custom OEM model only. Contact the factory for more information.

The model 3023 is a 2-leg zero-cross three-phase time propor- tioning SCR power controller.

 

The 3023 linearly controls the power applied to a three-phase electrical load proportional to a 4-20 mA command signal by operating an inverse pair of silicon controlled rectifiers (SCRs) in a zero-cross time proportioning manner.

 

The control circuit is powered by the electrically isolated 4-20 mA command signal. The cycle time can be field adjusted from 1 to 10 seconds by a single turn potentiomer on the circuit board. Multi-turn potentiometers are provided for zero and span adjustment.
