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

Euroamp 60_x000D_ 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._x000D_ Virtually zero electrical emissions_x000D_ Improved smoothness of motor operation_x000D_ Increased motor life_x000D_ Suitable for low inductance motors without the need for an additional choke_x000D_ 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._x000D_ Adjustable peak output current up to 4A_x000D_ Choice of velocity control using armature voltage sensing or tacho feedback_x000D_ Optional torque control or positional control using analogue positional feedback signal_x000D_ Optional automatic velocity ramp for smooth starts using stepped input signal changes_x000D_ Diagnostic LED display of drive condition
