Need a controller for a brushed dc motor (24V-50A)

I'm interested in control a dc brush motor 24V-50A. I only need forward and reverse control with an analog (potentiometer) input and a switch to control the direction.
Could you please recommend me the product?

With our controller you do not need the direction switch; the controller is inverting that is can reverse the direction of the motor.
What is the power of the motor (amperes or HP?)
How many motors do you need to control? Just one?

I'm developing a cleaning machine so I need forward and reverse control. The motor is 24v-50A -> 1200W -> 1.8 H.P.
Actually I only need one driver to make the prototype.

If you have only one motor then you can use the AX3500SC or the AX3500SC-BP SC stands for single channel, that is driving one motor at double the current.
