The MDCSL100-050301 driver is designed to drive DC brushless motors at currents of up to 30A (peak) and 50V. The current limit can be set with an adjustable potentiometer right on the top of the driver. This is a sensorless driver, so no hall sensors are needed. The MDCSL100-050301 is also easy to use. It has screw down style detachable terminal blocks which makes wiring simple. Featuring LEDs that indicate power and faults which make problems easy to diagnose.
