MSE421, McLennan Servo Supplies McLennan Servo Drive, 60 W, 10 → 30 V dc

Euroamp 60

This unit provides a continuous output power rating up to 60W, with precise servo control of dc servo motors. It operates from a single rail supply which enables battery operation if required. A MOSFET based linear output stage provides a number of advantages.

Virtually zero electrical emissions
Improved smoothness of motor operation
Increased motor life
Suitable for low inductance motors without the need for an additional choke

The amplifier is packaged on a standard extended Eurocard and uses surface mount technology to provide a compact unit, with high reliability. The differential amplifier based input stage provides the following features.

Adjustable peak output current up to 4A
Choice of velocity control using armature voltage sensing or tacho feedback
Optional torque control or positional control using analogue positional feedback signal
Optional automatic velocity ramp for smooth starts using stepped input signal changes
Diagnostic LED display of drive condition
