RD52.2-4B-005-L-A2-FW

The Bosch Rexroth Indramat RD52.2-4B-005-L-A2-FW drive from the RD 500 Drive Controllers series is a high-performance AC drive converter designed for precise industrial motor control. This Converter with a built-in brake chopper operates on a Nominal Connecting Voltage of 3 x AC 380-480 V with a tolerance of ±10% and delivers a Rated Power of 5.5 kW at a continuous current of 7 A. Engineered with forced air cooling and requiring a cooling airflow of 0.03 m³ to manage its 0.26 kW of power loss, the unit maintains optimal temperature. The compact housing measures 135 × 90 × 440 mm (W × D × H) and weighs just 6.5 kg, easing installation in dense control panels.

The RD52.2 model features an integrated brake chopper that provides continuous braking power of 2.8 kW and a peak of 18 kW for up to one second, backed by a minimum resistor value of 35 Ω. Its frequency output spans from 0 to 1400 Hz, enabling compatibility with both induction and synchronous motors across varied torque demands. Built-in radio interference suppression ensures compliance with EMC requirements, while firmware for the RD52.2-4B-005-L-A2-FW is ordered separately to match specific application needs. This versatile converter supports only supplier-approved accessories for guaranteed reliability.

Designed for rugged industrial environments, the RD52.2-4B-005-L-A2-FW operates between temperatures of 0 to +40 °C at up to 90% humidity (non-condensing) and can be installed at elevations up to 1000 m above sea level. Clearance above and below the unit is recommended to sustain airflow and simplify maintenance. Available through authorized distributors, it comes with a one-year warranty, making it an ideal solution for machine builders seeking precise motor control, reliable braking, and streamlined commissioning.
