Product Description:
The KDV 1.3-100-220-300-220 is a supply module produced by Bosch Rexroth Indramat within the KDV Supply Modules series. This unit converts a three-phase industrial mains line into a stabilized DC bus that powers multiple drive controllers in a shared-axis system. By feeding several compatible drive units from one source, it supports centralized power distribution for machines with coordinated motion. Its integrated bleeder circuitry also handles returned braking energy, helping keep the DC bus stable when connected motors decelerate.
The module draws a nominal line of 220 V AC and supports a continuous output of 100 A; during 300 ms surges it can deliver up to 300 A for acceleration peaks. Its internal link maintains 300 V DC, matching the voltage class used by Indramat DDS and TDM drives, and total conversion capability is rated at 30 kW. Auxiliary electronics consume 500 VA, while the ventilation fan adds 15 VA to the supply demand. A separate 24 V control tap can supply 8 A for contactors or I/O circuits, and the cabinet thermal load is 150 W from semiconductor losses. The ventilation duct removes this heat from the module interior during continuous operation.
The energy-dissipation path relies on a resistor bank that absorbs 2 kW continuously and tolerates bursts of 40 kW when regenerative braking is heavy; it can accept up to 60 kWs of returned energy before the drive must decelerate more slowly. The resistor bank converts returned electrical energy into heat during repeated braking cycles. Ambient operation is allowed to 55 °C, and nominal performance is available up to 1,000 m altitude, with derating required above that height. The enclosure can release a maximum of 2,000 W to the surrounding control cabinet, so the cabinet must provide enough airflow to carry that heat away. Total shipping mass is 21 kg, which affects mounting support and handling during installation.
