FEATURES & BENEFITS
1/20 to 2 Hp
SCR DC Regen
n MM footprint: Extremely compact size with an industry standard mounting footprint.
n 4Q reversing: Regenerative/4 Quadrant drives have the ability to perform quick, contactorless reversing on-the-fly!
n Speed range and regulation: 1% regulation over 50:1 speed range. 0.1% regulation over 60:1 speed range with the
addition of a tachometer for feedback.
n User adjustable calibration pots: IR compensation, min speed, max speed, forward and reverse current limit, forward
and reverse acceleration, and tachometer.
n Diagnostic LEDs: LEDs for forward and reverse direction, power, forward and reverse current limit status.
n Stopping modes: User can regeneratively decelerate (N.O.), regeneratively brake (N.O.) or coast the motor to a stop (N.C.).
n Spade terminals: Easy to use, lower cost, and able to fit in a smaller package.
n Additional features: Dual voltage AC input, switch selectable armature or tachometer feedback mode and automatic
deadband compensation for 50 or 60Hz power.
n -PCM option: Add a “-PCM” to the end of the part number to receive the drive with an isolation transformer daughter
card. See Adder Boards under Drives Accessories for details.
Minarik’s MMRGD Series is one of the smallest full-wave, full-featured
regenerative digital DC drives on the market. The dual voltage (115
or 230 VAC) MMRGD not only brakes and reverses DC brush motors
on the fly, but is also in the industry standard MM footprint (3.72" x
4.42").
The -PCM option can accept grounded or floating inputs. If only a
unipolar signal is available, there is a terminal input for reversing
direction by contact closure.
The MMRGD is compatible with our DLC600 digital controller if
tighter regulation of a unidirectional set speed is required. Contact
factory for connection diagram.
For applications that use limit switches, the use of the 200-0386A limit
switch logic board with the MMRGD may be a good choice!
