Product Description:
The KDS 1.1-100-300-W1-220 is a drive module produced by Bosch Rexroth Indramat for the KDS Servo Drive Modules series. Within multi-axis cabinets, it converts link-circuit energy into regulated AC output for servo motors, allowing coordinated motion profiles in automated machining cells, material-handling lines, and packaging machines. By combining power electronics with an auxiliary fan pack, the unit provides a compact way to deliver continuous motor current while staying within thermal limits during industrial operation.
The module can supply a continuous armature current of 93 A and a peak current of 100 A, providing additional capacity during acceleration without requiring a larger cabinet transformer. Its sustained mechanical output is rated at 30 kW, and the link-circuit bus operates at 300 V DC. Forced-air cooling channels move air across the heat sink, and the power electronics dissipate 150 W internally while another 400 W is released through series resistors, so enclosure airflow must account for both heat sources. Protection class IP10 limits the unit to clean indoor environments, and insulation category C indicates the permissible conductor temperature under load. The drive section weighs 15.2 kg, and its control electronics draw 1,450 mA from the +24 V signal supply, which affects panel layout and auxiliary power loading.
The attached fan assembly is protected by a 0.630A/250E cartridge fuse and operates from a dedicated 220 V line, which keeps blower faults separate from the DC bus. At 4.2 kg, the fan assembly adds little load to the mounting rail and provides the airflow needed for continuous operation in ambient temperatures up to 55 °C. Installation is allowed up to 1000 m above sea level without derating, while operation at higher elevations reduces air density and lowers forced-air cooling effectiveness.
