RD52.1-4B-400-F-V1-FW

The RD52.1-4B-400-F-V1-FW from Bosch Rexroth Indramat is part of the RD 500 Drive Controllers series, designed to deliver robust performance in high-power AC drive applications. Featuring a Nominal Connecting Voltage of 3 x AC 380-480 V and a Rated Power of 400 kW, this converter unit provides reliable energy control for demanding industrial systems. As a Converter with a built-in brake chopper, it offers precise braking control and seamless integration into automated motion processes. Its primary function is to regulate motor speed and torque by converting three-phase AC input into a variable-frequency output, ensuring optimized machine performance.

Incorporating a forced air cooling with integrated liquid circulation mechanism, the RD52.1-4B-400-F-V1-FW maintains stable operating temperatures even under continuous heavy load. The broad input voltage range of 380 to 480 V AC accommodates voltage fluctuations up to ±10%, enhancing resilience against power instability. The built-in brake chopper provides instantaneous energy dissipation during deceleration phases, reducing mechanical wear and improving safety. This drive controller supports a wide frequency output spectrum, allowing precise control from standstill up to its rated threshold, and ensures minimal harmonic distortion in the power grid.

Constructed to meet stringent industrial requirements, the RD52.1-4B-400-F-V1-FW offers superior compatibility with standard three-phase power networks and can be installed within control cabinets to protect against dust and debris. The integrated liquid-air cooling system enhances efficiency by combining the reliability of forced air circulation with the stability of liquid cooling loops. With its high power density and advanced thermal management, this drive converter delivers consistent performance, extended service intervals, and reduced downtime. Ideal for heavy-duty conveyor systems, milling machines, and extrusion lines, the RD52.1-4B-400-F-V1-FW maximizes productivity and cost-effectiveness in modern industrial environments.
