Motor Speed Control is bi-directional.
July 2, 2002 - WMC140 dc motor control provides forward and reverse control of battery powered brush type permanent magnet dc motors. It uses MOSFET PWM for variable speed operation and direction control. Thermal overload shutdown and adjustable current limit fold-back protect against excessive motor current from high starting or stall conditions. Models are available for 12 or 24 V applications up to 55 A.
