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.

Loadtrol

Loadtrol enables maximum material processing for applications with an AC processing motor and a DC feeder motor. Loadtrol monitors the load
on the AC motor and automatically regulates the speed of the DC motor to maintain a constant load on the AC motor.

If the processing motor is overloaded, Loadtrol slows the speed of the feeder motor. When overload is relieved, Loadtrol automatically Increases the feeder speed to its maximum.

This allows for maximum processing even when the materials are fed at an inconsistent rate.System response and operating range is set by using five on-board potentiometers and one Off board current set potentiometer.

Typical applications for Loadtrol include cotton gins, saw mills and rock crushers.

Application Cotton Gin

Ideally, the AC motor on the gin and the DC motors on the feeder run at full speed
so the gin operates at the maximum capacity. If the cotton on the feeder belt becomes too
thick, the increased volume can overload the gin motor. This raised the AC current in the motor.Loadtrol senses the increase in current. If the Current level rises above the current set level .Loadtrol automatically slows down the feeder until the gin catches up and the
overload is relived. When current drops to the normal level, the feeder returns to its full speed.
