1/50 to 1/4 Hp
SCR DC
MM31000 Series
Typical Applications
n Low Cost: Designed for OEMs.
n Speed range and regulation: 3% regulation over 20:1 speed range.
n User adjustable calibration pots: IR compensation, min speed and max speed.
n Removable terminal barrier: Greatly reduces miswiring; easy installation.
n Optional premounted speed potentiometer: Reduces wiring time and makes a compact package.
For cost-sensitive variable-speed applications requiring outstanding
performance, Minarik offers the MM31700 Series of SCR drives.
These light-weight compact drives control 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 equip-
ment manufacturers.
These MM Drives have a speed potentiometer rigidly mounted to an
L-bracket on the circuit board (MM3170B/51B only). 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.
