Violin

Miniature Analog DC Servo Amplifier for DC Brush Motors

Current mode servo amplifier

The Violin is a series of miniature current mode servo amplifiers for DC brush motors. Although highly compact, the Violin can support up to 25 amps continuous current. This high power density servo amplifier can deliver up to 5800 W of peak power or 2900 W of continuous power in a miniature package.

The servo amplifier offers significant operating features, including excellent output linearity and zero dead band performance. The Violin is a PCB mounted device that enables efficient, cost saving implementation.

Accessories
VIO-STARTER
VIO-STARTER
The VIO-STARTER is an add-on interconnection board for the VIO servo amplifier that plugs on top of the amplifier. The purpose of this board is the translation of the VIO solder type pins into screw type terminals thus enabling easy connectivity for evaluation and low quantity applications.
