OC2B is an open/closed chassis motor control that has been designed as building block solid state regulated power unit. OC2B uses state of the art control circuitry which can be used by itself, by wiring in the provided speed potentiometer as a straightforward speed regulated control or can be incorporated into much more sophisticated system designs contactor operation, external speed programming and tach feedback etc.

SPARTAN

I is a low-cost, totally enclosed SCR DC motor speed control which operates from a single-phase AC power source. The control is designed for quick and easy installation without having to make any adjustments.
