Description
The MM311U dual-voltage single quandrant SCR drive controls 90 or 180 VDC SCR brush-type motors ranging from 1/20 Hp through 1/4HP. The MM311U drive has integrated isolation allowing them to precisely follow analog current or voltage signals from external devices or a potentiometer as a reference for motor speed control. This results in significant labor and material cost reduction compared to other systems employing a seperate drive and isolation card. This multi-featured chassis drive accepts optional input for start and stop. Depending on the application, users can run the drive open-loop with armature feedback or closed loop with tachogenerator feedback for enhanced performance. The MM311U drive accepts nearly any DC tachogenerator (7-50 V/KRPM), scaleable using an adjustable tachogenerator gain potentiometer.MM3 Series MM311U MM300 & MM500 Series
