The MDC151 series is a Brushless Speed Controller designed to drive DC brushless motors at currents of up to 60A (peak). Model MDC151-050601 has an input range of 20 - 50 VDC. Using hall sensor feedback, a constant velocity mode can be selected. These controllers are protected against over current (cycle-by-cycle or latched), hall sensor error and under voltage. Included on the controller is an internal potentiometer to control the maximum phase current allowed into the motor and an internal potentiometer to control the speed of the motor. An external voltage (0-5VDC) can be used to control the speed as well. The direction of the motor can be preset by the direction control input. Other inputs to the controller include a run/stop and a motor freewheel input. When using the run/stop input, there are three ramp up/down profiles from standstill to select from. The run/stop input overrides all other inputs into the controller.

The MDC300-120151 driver is designed to drive DC brushless motors at currents of up to 15A and 170VDC. Using hall sensor feedback, a constant velocity mode can be selected. The driver is protected against over current (cycle-by-cycle or latched), hall sensor error and under voltage. When an error occurs, a fault light and an optically isolated open drain output is turned on to notify the user. Included on the driver is an internal potentiometer to control the maximum phase current allowed into the motor and an internal potentiometer to control the speed of the motor. An optional external potentiometer or voltage input can be used to control the speed as well. The direction of the motor can be preset by the direction control input or controlled by the external voltage speed input. Other inputs to the drive include a run/stop and a motor freewheel input. An onboard potentiometer sets the ramp up/down profile from standstill. The run/stop input overrides all other inputs into the driver.
