Heavy Duty Control is designed for bi-directional control of 24 volt DC motors. This control is intended for high current applications. The output is rated for a 50 amp continuous load and up to a 200 amp intermittent load (10% duty cycle). This system is ideal for controlling lifts, jacks, winches, and agricultural applications where large capacity 24 Volt polarity reversing DC motors are used. The control is waterproof and suitable for use in harsh environments. The dimensions are approximately 3.5″ L x 3″ W x 2.5″ H. There are four screw terminals for the power connections. Two connect 24 volts and Ground and the other two connect to the DC motor. Additionally, there are three screw terminals for connecting low power leads from a control switch.
