RGM400-1.5 DC Motor Control


The RGM series is a full featured regenerative SCR type drive series designed specifically for demanding applications where quickly stopping or reversing a PMDC motor is a requirement. With a widely used industry footprint standard, these compact 4Q drives eliminate the need for bulky mechanical relays or switches to reverse motor direction. As with all our 4Q drives, these units come standard with user adjustable trim pots for Max Speed, FWD/REV Torque, Acceleration, Deceleration, DB, Min Speed, Tach, and IR Comp. With these adjustments, a drive can easily be tuned to run almost any PMDC motor in the 1/20th to 2 HP range. Also available on the RGM series is a factory installed isolation module that allows the drive to be controlled via a non-isolated 4-20 mA or 0 to ±10 VDC command signal. With many user selectable stopping or enabling modes and Tachogenerator feedback, the RGM series is a versatile drive that can satisfy your reversing and control needs.
