INTROL Model 636

Regenerative DC Motor Controller

Introl Model 636 is a 3 phase full wave four quadrant regenerative control for use on DC motors up to 50 HP. The control operates on 230/460 VAC 3 phase, 50/60 Hz power. The twelve SCR power bridge provides improved efficiency and better form factor which results in cooler operation. The Model 636 is packed with features not found on most controls. Microprocessor design provides faster response for use in servo applications. The control also works exceptionally well in torque applications. Microprocessor design also provides improved fault detection, programmable operation modes, programmable overload along with many other features.
