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.

Field Supply: Voltage output to energize the field winding of a shunt-wound motor

3-Wire Start/Stop: On-board latching relay allows for use of momentary Start/Stop pushbottons

Isolation Logic: Allows floating or grounded 0 - 10 VDC or 4 - 20mA signals. Burr-Brown provides .01% linearity

On-board Fusing: Drives include on-board fusing

Tach Feedback: Accepts tachogenerator feedback for tighter speed regulation

Multi-turn Trim Pots: Minimum Speed and Maximum Speed use 12 turn trim pots for finer tuning

1% Base Speed Regulation over 60:1 Speed Range

0.1% Base Speed Regulation over 80:1 Speed Range with Tach
