The MDCKB1-120081 is a Brushless DC Driver with a constant velocity mode. This driver eliminates the need for an external power supply with a motor bus voltage of 160VDC and a maximum phase current of 8A (peak). A constant velocity mode was achieved through use of a Hall Sensor Feedback. The driver is protected against over-current (cycle-by-cycle), hall sensor error and under-voltage. A Fault LED Light illuminates to notify the user when an error occurs. This driver utilizes an internal potentiometer to control the maximum phase current allowed into the motor and an external potentiometer to control the speed of the motor.
