UNITROL Phase Shift FOR SALE from Weld Systems Integrators, Inc.
#9190 – PSS Series Heat Control Board
This Phase Shift Control board fills the need for a simple solid-state system to control any size SCR contactor. It is typically used for resistance welder transformer control, but can also be used for pure resistive loads. The control uses RC timing to allow settings from 10% to 99%. A manual power factor adjustment potentiometer is provided to match the control to the inductive load.
A single-turn potentiometer is provided for heat adjustment. This potentiometer can be located either on a remote cable, the front of the control board, or on the back. These mounting options allow for use in any application.
INPUT LINE VOLTAGE: 115V – 575V, field selectable, 60/50Hz (specify frequency when ordering) SIZE: 4-3/4” x 6-1/2” x 1-1/4”
