RD52.1-7N-090-L-V1-FW

The Bosch Rexroth Indramat RD52.1-7N-090-L-V1-FW is a high-performance module in the RD 500 Drive Controllers series designed as a DC supply inverter for precise drive control applications. This unit operates on a nominal connecting voltage of DC 530-670 V and delivers a rated power of 90 kW. Equipped with forced air cooling, it ensures consistent thermal management under demanding load conditions. As an inverter without a built-in brake chopper, it offers a streamlined solution for drive systems requiring efficient power conversion and compact integration.

In technical operation, the RD52.1-7N-090-L-V1-FW maintains vector control precision while handling dangerous DC link capacitor voltages for up to 30 minutes after power-off. The device incorporates exposed live parts that require strict adherence to safety guidelines during installation and maintenance. Its design mandates a protective conductor with a minimum cross-section of 10 mm2 (AWG 6) to ensure grounding reliability. Additionally, firmware for the unit is supplied separately, allowing tailored updates and configuration in the field.

Beyond core performance, this inverter features a standby power supply and can be mounted directly adjacent to other drives without air gaps, optimizing cabinet space. It weighs 74 kg and operates up to 50° C ambient temperature, with a power reduction rate of 2.5% per K above this threshold. Power loss is rated at 2.7 kW during continuous operation. Conforming to EN 55011 / EN 61800-3 standards with a radio interference suppression level of A1, it ensures compliance and immunity in industrial environments. Connectivity is provided via an RS 485 interface with USS protocol on the X12 connector, facilitating seamless PLC integration. This robust and efficient inverter enhances system reliability, installation flexibility, and overall drive performance in industrial automation applications.
