Product Description:

The KDV 2.1-100-220-300-220 is a supply module manufactured by Bosch Rexroth Indramat and used in the KDV supply module range. In an automation cabinet, it takes incoming utility power, rectifies it, and maintains a common DC bus for multiple servo or spindle drives so coordinated axes can share the same energy source. The unit installs on a DIN rail or back panel next to the motor inverters, allowing short wiring runs while centralizing protective devices such as contactors and circuit breakers.

The module delivers a continuous power throughput of 24 kW, allowing it to energize several medium-frame drives without exceeding thermal limits. On the DC side, it regulates the link voltage at DC 300 V, which matches the internal operating range of Indramat drive controllers. The mains connection is rated for AC 220 V nominal and accepts a balanced three-phase AC network to reduce line current per phase. During steady operation, the supply draws up to 100 A, so upstream fusing and conductor sizing must match that demand. These values describe the electrical load the cabinet must support during simultaneous axis acceleration or when regenerative braking feeds energy back to the bus.

Thermal management relies on an external fan unit to move cooling air through the housing. The module contains 2 fans that direct airflow across the heat sink and power semiconductors to keep internal temperatures within an acceptable range. Because the blower motors operate from a dedicated auxiliary line, airflow remains available whenever the cabinet is energized. This arrangement helps limit heat soak during standby and supports stable operation under continuous load. Wake Industrial offers a one-year warranty on the Bosch Rexroth KDV 2.1 supply module. Furthermore, Wake Industrial can arrange international shipping options on this product for customers who are not located in the United States.
