Product Description:
The KDS1.1-100-300-W1/115A is a servo drive module produced by Bosch Rexroth Indramat within the KDS Servo Drive Modules series. It interfaces with the common DC bus of an Indramat drive rack and supplies regulated power to synchronous and asynchronous servo motors used in industrial positioning and process lines. By integrating the power section, current control, and dedicated cooling hardware in one housing, the unit simplifies cabinet layout for automated machinery. This arrangement also lets the rack distribute bus power across multiple axes while the module regulates motor demand at its installed position.
This module can deliver a continuous output of 30 kW while providing up to 93 A of current under steady load and a peak output of 100 A for short acceleration bursts. The internal DC link is rated at 300 VDC, so connected inverters receive a stable intermediate voltage. A mounted fan moves cooling air across the heat sink, and the fan operates from 115 VAC with protection by a 1.25 A/250 E fuse. During normal operation, the 24 V control rail draws 1.45 A, and the power electronics dissipate 150 W internally plus 400 W externally. Those separate heat-loss values help show how much heat remains in the cabinet and how much is carried away by the cooling path. Protection type IP10 limits ingress to large objects, so the drive must be installed in an enclosed rack. Humidity is restricted to class F conditions.
The aluminum housing weighs 15.2 kg, which remains manageable for rack installation and removal. Rated ambient temperature extends up to 55 °C, enabling operation in hotter production areas when airflow is maintained. Altitude use is limited to 1000 m above sea level to keep component temperatures within safe limits at standard cooling air density. The insulation category C supports the required creepage distances and clearances for the power section. These operating limits are intended for enclosed industrial drive racks where airflow and mounting space are controlled by the machine design.
