Product Description:

The KDS 1.1-100-300-W0 is a servo-drive module manufactured by Bosch Rexroth Indramat and supplied within the KDS Servo Drive Modules series. Designed as a power section for modular drive systems, this unit converts the common DC link voltage into controlled three-phase output for synchronous or induction motors used in material handling, packaging, and general automation. As a drive module, it forms part of the axis loop and delivers current and voltage commands while upstream controller boards generate the motion profiles.

Under steady operating conditions, the drive can supply a continuous current of 45 A, allowing long-duration torque delivery without excessive heating. Its internal bus is fed from a link circuit held around 300 V DC, and the power devices dissipate heat to the surrounding air through natural convection, so no additional fans are required in the cabinet. During short accelerations, the module tolerates a peak output of 100 A. The transistor bridge is rated for a motor power of 30 kW, giving it capacity for medium-power servo axes. The enclosure has a protection class of IP 10, which helps limit accidental contact with live parts but does not provide dust or liquid sealing.

The permissible ambient operating range is +5 to +45 °C, which keeps the module within its intended thermal limits during normal duty. The assembly weighs 15.2 kg, and that mass also supports passive heat dissipation through the housing during operation. Within the product line, the unit is identified as Model 1. This designation places it in the first KDS module generation and helps distinguish it within the series. The combination of convection cooling, open enclosure protection, and DC-link operation makes it suitable for installation inside a protected control cabinet with adequate airflow and spacing.
