Minarik’s MM20000 Series of drives
housed within an aluminum NEMA 1 enclo-
sure guarantee protection from hands,
falling dirt, or any other unwanted external
solid objects that present a hazard.
Additionally, the MM21251C and
MM23201C have non-regenerative revers-
ing and dynamic braking capability accessi-
ble through switches on the front of the
enclosure. Users make all wire terminations
at the screw terminal strip inside the enclo-
sure, and operate the drive through the pre-
mounted speed potentiometer, power
switch, and brake or reversing switch when
applicable.
We offer four different MM drives that fit in
NEMA 1 enclosures. Each drive is depend-
able and adept at controlling DC SCR
brush-type motors in variable-speed appli-
cations from 1/20 to 2 Hp. Using full-wave
rectification of the AC line input, these SCR
drives provide a 60:1 speed range. The
MM21151C and MM21251C are filtered
drives that output 0-130 VDC to the motor
with a 1.10 form factor. We offer single and
dual voltage drives which operate from 115
VAC or 115/230 VAC, to run 90, 130 or
180 VDC motors.
