Minarik Drives MM31751B

For cost sensitive variable speed applications requiring outstanding performance, Minarik offers the MM31751B SCR drive. This light-weight compact drive controls DC brush type motors ranging from 1/50 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.

The MM31751B drive also has a speed potentiometer rigidly mounted to an L-bracket on the circuit board. 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 moderate 20:1 speed range.
