KDA 3.1-150-3-DY0-U1

Product Description:

The KDA 3.1-150-3-DY0-U1 is a cabinet-mounted servo drive unit built for heavy-duty use inside automated systems. It runs on 230/400 V AC input and delivers a continuous output current of 150 A. That’s enough current handling for machines that run large motors or require steady torque feedback without voltage dips. It belongs to the KDA series by Bosch Rexroth Indramat and works best when installed as part of a coordinated multi-axis drive setup.

The internal control is based on an analog interface, keeping configuration and feedback simple while maintaining responsive performance. The forced air cooling system pushes heat out through structured airflow—especially useful in tight cabinet racks with minimal space for passive airflow. The drive supports 50/60 Hz frequency range and weighs around 25 kg—not exactly light, but built for stable frame mounting. It’s designed with a diagnostic display too, so fault codes and system status can be seen directly on the unit without opening panels.

For protection, the enclosure is rated at IP20, which is fine for sealed cabinet use but not meant for open-air exposure or dusty environments. It’s a 3-axis model, which means it can coordinate across multiple motor systems when used with the correct controller. The cabinet mounting frame makes it secure for vertical installation, and its wiring points are organized to reduce install time. The build and layout reflect Bosch Rexroth’s typical approach—solid, industrial, and made to last under continuous workloads. With the KDA 3.1-150-3-DY0-U1, the output stays stable even when system demand jumps, and once integrated properly, it handles long production cycles with little drop in efficiency or performance.
