Minarik’s RG500A Series consists of full-wave, four-quadrant regenerative
SCR drives in a NEMA 4X enclosure to provide smooth motoring and braking
torque for brush-type DC motors. Mounted operators include power on/off
switch, speed potentiometer and reverse/brake/forward switch. These drives
are ideal in applications requiring protection from washdown, splashing liq-
uids, corrosive material, windblown dust, incidental contact with enclosed
equipment, or any external solid objects.
Slide switches allow the RG500A and RG510A drives to accept a 115 or 230
VAC input to run 90 or 180 VDC motors. A field supply is also provided for
shunt-wound motors. The switch selectable tachometer feedback mode virtu-
ally guarantees constant set speed under varying load.
The RG is compatible with the PCM4 signal isolator, the DLC digital controller
and the 200-0386A limit switch logic board.
Applications with overhauling loads, rapid deceleration, basic positioning,
and high duty cycle reversing and braking benefit from these versatile regen-
erative drives.
n NEMA 4X enclosure: Rugged metal enclosure protects against dirt, water and corrosive agents.
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. Armature or tachometer mode is switch selectable.
n User adjustable calibration pots: IR compensation, forward torque, reverse torque, tachometer, min speed,
max speed, forward acceleration, reverse acceleration and deadband.
n Diagnostic LEDs: Power On light on front of enclosure.
n Stopping modes: User can regeneratively brake (run/brake), coast the motor (power on/off switch), or
decelerate to a stop (N.O.). User can also decelerate to min speed (N.C.).
n Screw terminal block: Easy and secure wire terminations.
n On board fusing: No need to add external fusing for protection of your drive.
