Product Description:

The KDS 1.1-030-300-W0-220 belongs to the KDS Servo Drive Modules series manufactured by Bosch Rexroth Indramat. It is a servo drive module that supplies regulated power to downstream drives and returns regenerated energy to the link circuit, making it suitable for multi-axis industrial automation racks. Designed for cabinet installation, the unit supports a DC link and works with auxiliary control supplies to power logic and sensor chains. In coordinated systems, this arrangement helps connected axes share available energy during acceleration and braking.

The module can deliver a continuous mechanical output of 9 kW from a stabilized DC bus of 300 V ± 15%. Its output section is rated for 30 A rms, while the continuous current under thermal equilibrium is 25 A. External dissipation caused by switching and cabling totals 130 W, so the surrounding enclosure must remove that heat. Cooling is handled by natural convection, and an AC 220 V, 50–60 Hz cabinet fan can be added to improve airflow. The internal logic draws 750 mA from the +24 V bus, while monitoring electronics draw 50 mA from an external +24 V feed. The unit is assigned to humidity class F and insulation category C, and it can be mounted at altitudes up to 1000 m. Continuous operation is permitted in ambient temperatures from +5 °C to +45 °C.

Total internal heat generation is 60 W. The enclosure can operate in ambient air up to 55 °C for short-term duty cycles without derating, provided convection paths remain unobstructed. A mass of 14.1 kg supports rigid mounting on standard backplanes, and mechanical fastening follows the series 1 layout. The housing has an IP10 rating that permits chimney flow while helping prevent accidental contact with internal parts. This open enclosure style depends on clear vertical air paths inside the cabinet rather than sealed-air recirculation.
