RD52.1-5B-315-F-V1-FW

The Bosch Rexroth Indramat RD52.1-5B-315-F-V1-FW from the RD 500 Drive Controllers series delivers robust AC drive conversion with a nominal connecting voltage of 3 x AC 500 V and a rated power of 315 kW. This converter with a built-in brake chopper employs forced air cooling with integrated liquid circulation for efficient thermal management under heavy loads. Designed for versatile industrial use, it accepts a wide input frequency of 50/60 Hz and interfaces seamlessly with Rexroth automation ecosystems. Compact yet powerful, it supports dynamic machine tools, packaging lines, and printing presses with precision control.

This drive converter provides a rated motor output of 200 kW across a frequency range of 0–250 Hz, drawing a rated current of 400 A at nominal conditions. It withstands a peak current of 520 A for 60 seconds and up to 680 A for 1 second, delivering a peak power of 342 kVA during transient load spikes. Built to endure challenging environments, the unit meets environmental class 3K3 standards and features an A1 radio suppression level to minimize electrical interference.

The permissible temperature range of 0–40 °C (with operation up to 50 °C at a derating rate of 2.5% per K) ensures reliable performance in variable climates. An airflow requirement of 0.8 m²/s paired with a power loss of 9.5 kW under rated conditions highlights its optimized efficiency and cooling design. Backed by Bosch Rexroth Indramat’s global support network and warranty coverage, the RD52.1-5B-315-F-V1-FW is engineered for durability, serviceability, and seamless integration in high-demand automation installations.
