1/20 to 2 Hp
SCR DC Regen
Minarik’s RG500 Series consists of full-wave, four-quadrant regenerative
SCR drives to provide smooth motoring and braking torque for brush-type
DC motors. Use the RG510UA to control motors from 1/20 through 1/4
Hp, or the RG500UA from 1/4 through 2 Hp, for single or bi-directional
variable speed, without using mechanical contactors.
Slide switches allow the RG500UA and RG510UA drives to accept a 115
or 230 VAC input to run 90 or 180 VDC motors. The tach feedback
mode virtually guarantees constant set speed under varying load.
Applications with overhauling loads, rapid deceleration, basic positioning,
and high duty cycle reversing and braking benefit from these versatile
regenerative drives.
RG500UA Series
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, forward torque, reverse torque, tachometer, min speed, max
speed, forward acceleration, reverse acceleration and deadband.
n Stopping modes: User can decelerate (N.O.), regeneratively brake (N.O.) or coast the motor to a stop (N.O.). User can
also decelerate to min speed (N.O.).
n Cage clamp terminal block: Quick and easy wire terminations.
n On board fusing: No need to add external fusing for protection of your motor or drive.
n Additional features: Dual voltage AC input, switch selectable armature or tachometer feedback mode and field supply for
shunt wound motors.
n Options and Accessories: “-PCM” option adds Burr Brown isolation, 201-0024 inhibit plug for regenerative brake option,
and 200-0386 limit switch logic board.
