DKR04.1-W400

The Bosch Rexroth Indramat DKR04.1-W400 drives high-performance automation tasks within the DKR Drive Controllers series and is engineered for environments demanding a rated current of 400 A. This controller features an air (built-in blower) cooling method to maintain optimal thermal conditions under sustained load. Built on design version 1 with a dedicated line series 04 topology, the unit ensures compatibility across existing Rexroth Indramat Bosch architectures. Its compact footprint and robust construction suit both retrofit installations and greenfield projects.

Reliability is underpinned by a standardized product series DKR platform, which simplifies spare-parts logistics and accelerates commissioning cycles. The controller’s internal electronics include a passive bleeder stage to manage DC-link voltage stabilization, while command communication interfaces remain open for integration with external automation networks. Precision manufacturing and quality checks conform to Bosch Rexroth’s strict guidelines, ensuring every module meets performance tolerances. Seamless digital integration is enabled through the controller’s adaptable firmware and flexible I/O configurations.

Maintenance benefits from the integrated blower design and easily accessible service ports, minimizing downtime and reducing mean time to repair. The DKR04.1-W400’s modular frame and consistent mechanical dimensions allow rapid replacement or expansion without special tooling. Altogether, this controller provides a professional-grade solution for demanding industrial-motion applications where high current capacity and reliable cooling are essential.
