Product Description:
The KDS1.1-50-300-W0 is a servo-drive module built by Bosch Rexroth Indramat and belongs to the KDS Servo Drive Modules series. As a modular power stage, it conditions DC bus energy and delivers regulated current to synchronous or induction motors used in automated handling, packaging, and machining lines. Within multi-axis cabinets, it pairs with higher-level controllers to translate velocity and torque commands into motor power, serving as a central actuator component in industrial automation systems.
The module sustains a continuous output of 15 kW while supplying up to 35 A of motor current from a DC link maintained at 300 VDC. For short acceleration demands, it tolerates a peak of 50 A without derating. Heat is removed by natural convection, so cabinet airflow planning is essential. Internal dissipation reaches 70 W during rated operation, and the electronics draw auxiliary currents of 950 mA at 24 V, 140 mA from the positive 15 V rail, and 50 mA from the negative 15 V rail for signaling. These values help size control power supplies and monitor bus loading. The drive may be mounted up to 1000 m above sea level without adjustment, and its continuous current capability supports tightly regulated servo motion across typical machine duty cycles.
The housing weighs 14.1 kg, allowing direct panel installation without added supports. At full load, the power stage releases 150 W to the surrounding air, and that value must be included in cabinet thermal balance calculations along with the internal loss already noted. The enclosure carries a protection rating of IP10, indicating finger-safe access but no sealing against dust or fluids, so placement inside a clean control cabinet is required. Operation remains nominal up to an ambient temperature of 55 °C, after which current limits apply to protect semiconductor junctions.
