Servostar 300

The fully digital SERVOSTAR™ 300 is the consequent supplement to the well introduced SERVOSTAR™ amplifier family. Especially the demand for more compact amplifiers and single phase supply of many customers pushed for this product line. As all other SERVOSTAR™ amplifiers also the S300 comes with all EMC filter onboard. Several extension cards for fieldbus connection or I/O extension are available. We offer complete servo system with amplifier, motors and ready to use cables.
