RG510UA DC Motor Control

RG500 Series

Minarik Drives' RG510UA is a full-wave, four-quadrant regenerative SCR drive that provides smooth motoring and braking torque for brush-type DC motors ranging from 1/20 through 1/2 HP, for a single or bi-directional variable speed, without using mechanical contactors.

Slide switches allow the RG510UA drive to accept a 115 or 230VAC input to run 90 or 180VDC motors. The tach feedback mode virtually guarantees constant set speed under a varying load. Applications with overhauling loads, rapid deceleration, basic positioning and high duty cycle reversing and braking benefit from this versatile regenerative drive.

Potentiometer Kit 202-0003 is included with a purchase of the RG510UA
