Product Description:

The KDV 1.3-100-220-300-W1-115-220 is a supply module produced by Bosch Rexroth Indramat for the KDV Supply Modules series. It converts utility power into a stabilized DC link that feeds multiple servo drives, and it houses an internal bleeder stack to absorb regenerated energy during braking events. Deployed on the panel back-plane of an electrical cabinet, the unit forms the central power backbone for coordinated motion axes in industrial automation cells.

The module accepts a three-phase mains of 220 V AC, and its input path is rated for 100 A of continuous current under nominal conditions. Internally, it maintains a DC bus of 300 V DC, allowing drives to draw up to the module’s rated power limit of 30 kW. For short 300 ms transients, it can deliver a peak current of 300 A, enabling rapid motor acceleration without voltage sag. Non-drive loads such as logic circuits draw 500 VA of auxiliary power from an isolated secondary supply. While operating, the electronics dissipate 150 W into the cabinet, and the design permits a maximum of 2000 W to be carried away by external airflow, figures that guide enclosure ventilation sizing.

The regenerative path is dimensioned for 2 kW of continuous bleeder dissipation and a peak of 40 kW, so high-inertia stops do not overcharge the bus. Up to 60 kWs of feedback energy can be absorbed in a single braking cycle before thermal limits are reached. The assembly is blower cooled by an integral fan that consumes 15 VA at 115 V AC, keeping component temperatures within limits. Panel mounting simplifies service access, and the enclosure carries a protection rating of IP 10, giving basic shielding against accidental contact with live parts while relying on the cabinet for additional protection.
