MBDC050-050101

The MBDC050-050101 is a speed controller designed to drive DC Brush Motors at currents up to 10A peak at an input voltage range of 20-50VDC. An onboard 10k potentiometer is used to set the peak motor current limit between 1.0-10.0A. The direction of the motor can be preset by the direction control input on terminal block 1. The freewheel input will override all other inputs into the driver. This speed controller features protection from over current (cycle-by-cycle) and over voltage. The fault protection is set for cycle-by-cycle motor turn-off. Cycle-by-cycle over current limiting is done by monitoring the peak motor current and when the current is above the value set by the external potentiometer, the motor phases are immediately turned off and held off for the remainder of the internal PWM oscillation. A red fault LED illuminates to notify the user when an error occurs.
