Product Description:

The KDS1.1-150-300-W1-115 is a servo-drive module manufactured by Bosch Rexroth Indramat in the KDS Servo Drive Modules series. It functions as a power stage that interfaces with a shared DC bus to energize three-phase motors in automated production lines, pick-and-place gantries, and packaging systems. By supplying regulated current while accepting command signals from a separate controller, the module supports precise torque control in coordinated motion systems. Because the power stage is separate from the higher-level controller, it can be integrated into systems where motion commands and power conversion are handled by different modules.

The power rail is maintained at 300 VDC, and the design tolerates fluctuations of up to ±15% without shutdown. Under continuous duty, the unit delivers 96 A, enabling roughly 45 kW of mechanical output. Momentary surges can reach 150 A, giving machines added acceleration capacity during short demand peaks. Internal switching elements dissipate 160 W, while the control electronics draw 140 mA from the +15 V supply and 1.95 A from the +24 V rail. The module uses forced ventilation, and the IP10 housing allows airflow while helping prevent accidental finger contact with live conductors. This arrangement suits enclosed cabinets that provide directed air movement across the heat sink.

The cooling circuit uses a cabinet blower fed from 115 VAC at 50/60 Hz. Heat carried away from the heat sink accounts for an external loss of 430 W, which must be removed by the enclosure ventilation system. The drive section itself weighs 15.4 kg, supporting secure panel or rail mounting in industrial cabinets. Installations are approved up to 1000 m above sea level, and operation above that elevation requires derating because thinner air reduces cooling effectiveness. The blower and exhaust path should be arranged so warmed air does not recirculate around neighboring power components.
