DMA 045A 1301-D

The Bosch Rexroth Indramat DMA 045A 1301-D is a high-performance three-phase module from the DMA Servo Drive Modules series, designed for precision control in demanding industrial environments. As part of the Servodyn-D Series, this unit features a native SERCOS interface and fully supports resolver-based feedback to ensure accurate positioning and fast response. Compact yet robust, the DMA 045A 1301-D measures 50 mm width, 520 mm height, and 288 mm depth, fitting neatly into standardized drive cabinets. Built around a three-phase topology, it integrates seamlessly with servo and asynchronous motor systems for versatile automation applications.

Operating on an Input Voltage of 670V and delivering 400V Output Voltage, the module draws 1.32 A at 24 VDC auxiliary supply input while providing a continuous 45 A output current rating at a 2 kHz switching frequency. Its air-cooled design maintains optimal thermal performance within an ambient temperature window of 0 to 45 °C, aided by a recommended 100 mm clearance above and below for unrestricted airflow. The unit’s efficient cooling allows high-density installations without derating, ensuring stable operation in compact switch gear.

Encased in an IP20 protection housing compliant with EN 60 529, the DMA 045A 1301-D is ideally mounted inside an IP54-rated cabinet equipped with dust filters at all air inlets and outlets. It meets the 3K3 climatic category per EN 60 721 and sustains −25 to +70 °C storage temperatures without degradation. Mechanical resilience is guaranteed by a 15 g shock rating (DIN IEC 68-2-27) and 1 mm vibration displacement at 2–13.2 Hz, while altitude operation reaches up to 1 000 m without derating (and up to 3 000 m with derating). Units are backed by a one-year warranty from Wake Industrial, ensuring reliable service and support.
