Minarik Drives' RG500A consists of a full-wave, four-quadrant regenerative SCR drive 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. This drive is ideal in applications requiring protection from washdown, splashing liquids, corrosive material, windblown dust, incidental contact with enclosed equipment or any external solid objects.
Slide switches allow the RG500A to accept a 115 or 230 VAC input to run 90 or 180 VDC motors. A field supply is also provided for shunt motors. The switch selectable tachometer feedback mode virtually guarantees constant set speed under varying load.
The RG500A 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 this versatile regenerative drive.
