Bosch Rexroth DKR02.1-W300B-BA03-01-FW is a high-power drive controller in the Indramat DKR family for controlled servo, main-spindle and CNC drives. The complete type number is essential when selecting a spare because the current class, cooling arrangement, functional version and firmware must match the existing machine. The DKR02 manual assigns the W300 version to the 300-A device class and specifies a 3 x AC 400 to 480 V mains connection with ±10 percent tolerance. The control supply is AC 230 V with 200 VA power consumption. At a 4 kHz switching frequency, the controller provides 141 A continuous current and approximately 55 kW continuous power; at 8 kHz, the documented values are 110 A and approximately 43 kW. Peak current is 212 A and peak power approximately 93 kW. During braking, the controller can return energy to the mains: the data sheet specifies approximately 43 kW continuous regenerative power and up to 93 kW for no more than ten seconds. Output voltage reaches 380 V, while maximum output frequency is 800 or 1600 Hz depending on switching frequency. A built-in fan removes heat through the air duct. Total power dissipation at continuous current is approximately 1800 W, including about 1200 W in the air duct. The approximate 104 kg device weight must be considered for transport, cabinet design and installation. For recommissioning, also compare firmware FWA-DIAX03-ASE-02VRS-MS, motors, feedback, parameter set, terminal assignment and airflow with the existing DIAX03 system. Bosch Rexroth DKR02.1-W300B-BA03-01-FW remains the exact reference for this replacement.

For the W300 version, the DKR manual states 141 A continuous current and approximately 55 kW continuous power at 4 kHz and 212 A peak current. The mains connection is 3 x AC 400 to 480 V.
Compare the complete type number, BA03 functional version, firmware version, motor and feedback, terminal assignment, parameter set, airflow and cabinet space of the existing DIAX03 system.
Yes, we provide a 14-day functional guarantee for used items. This means the component must be operational when received.
Please note that the guarantee only applies when the warranty seal is undamaged.
If a defect occurs within 14 calendar days, please contact us in writing. Subject to availability, we will provide a replacement or refund the full purchase price after return.
Further details are provided in the terms and conditions supplied with your quotation.
We generally dispatch immediately - in many cases on the same working day. For particularly urgent requirements or machine downtime, we find a suitable solution as quickly as possible and provide a specific delivery window on request.
Express shipping or collection from our premises is also possible, depending on the situation. State your requirements during the ordering process or contact us directly.
We ship worldwide and work with reliable shipping partners, from parcel services to freight forwarding. Freight shipments normally require some preparation so the goods arrive safely and undamaged.
Payment is normally made by bank transfer against invoice. Payment is due within 10 calendar days of receiving the goods.
As a rule, we offer purchase on account for all customers. In individual cases, such as new customers or particularly high-value components, we may agree advance payment. This decision is made individually and communicated transparently.
Because we sell exclusively to business customers (B2B), there is no general right of return and no consumer right of withdrawal.
Please note that returns of functioning goods are generally excluded. In justified exceptional cases, we can assess an individual solution, but this is not the standard procedure.
For larger order quantities or several items of one type, we can offer individual discounts.
Simply send us a quick enquiry - we check availability and will gladly prepare a tailored quotation with quantity pricing.
Yes, we also purchase automation components, such as frequency inverters, PLC assemblies, panels, servo motors and CPUs. Components from Siemens, Lenze, Schneider Electric, Control Techniques or Heidenhain are especially sought after, and other brands are also possible.
The process is straightforward: email us an inventory list or overview photos at info@reha-industriekomponenten.de. We calculate a market-based purchase price and send you an offer.
