Product Description:

The KDS 1.1-100-300-W1-115/S102 is a servo-drive module manufactured by Bosch Rexroth Indramat for the KDS Servo Drive Modules series. It mounts in a modular drive rack where it converts the shared DC link energy into regulated three-phase output for synchronous or induction motors in automated production lines. By coordinating with digital controllers, the unit supplies the commanded current and voltage profiles that position axes, synchronize conveyors, or vary spindle speed in industrial machines.

The module can deliver up to 30 kW of power to connected servo motors. This value indicates the maximum mechanical work that can be transferred through the DC bus. During continuous operation it supplies a line current of 93 A, while transient demand is covered by a peak rating of 100 A. The internal link circuit is energized at 300 V DC with a permissible ±15% deviation, so the upstream supply must remain within that band to avoid undervoltage or overvoltage faults. An integrated fan draws its supply from a separate AC 115 V, 50–60 Hz branch, isolating cooling from the drive power path. Thermal limits allow reliable service between +5 to +45 °C, and the housing carries an IP10 protection level that guards against incidental contact with live parts.

For installations that demand constant airflow, the designated external fan unit is the LE4, which bolts directly onto the heat sink and maintains the forced-air channel used by the module. This cooling arrangement is described as forced ventilation, meaning the heat-generating power electronics rely on the fan rather than natural convection for temperature control, so adequate clearance must be provided around the outlet. With a mass of 15.2 kg, the drive requires rigid panel mounting. The unit is model 1 and series 1, so it matches KDS rack systems with the same DC bus bars and interface dimensions.
