The 512C converter is suitable for the control of Permanent Magnet and Shunt Wound DC Motors. The converters are designed to operate from a single phase ac mains supply in the range of 110Vac to 415Vac at 50 or 60Hz. A simple transformer tap arrangement allows the converter to be programmed to suit the applied voltage. The Speed of the DC Motor is controlled using a linear closed loop system with a feedback signal from either tachogenerator or armature voltage, the feedback source being switch selectable.
