For cost sensitive variable speed applications requiring outstanding performance, Minarik Drives offers the MM32750B SCR drive. This light-weight compact drive controls DC brush type motors ranging from 1/8 to 1/4 HP, without any additional components required. Reduced circuitry allows the cost to decrease significantly and also lends to a very compact package, ideal for original equipment manufacturers.
A prewired removable terminal barrier eliminates nearly half of the wiring required for other drives. Using full-wave rectification of the AC line input, these SCR drives provide a moderate 20:1 speed range. The MM32750B drive has a speed potentiometer rigidly mounted to an L-bracket on the circuit board.
Wiring Harness 201-0071 are included with a purchase of the MM32750B
