RD52.1-4B-004-P-NN-FW

The Bosch Rexroth Indramat RD52.1-4B-004-P-NN-FW from the RD 500 Drive Controllers series is a high-performance AC drive converter by Bosch Rexroth Indramat. It features a Nominal Connecting Voltage 3 x AC 380-480 V with a tolerance of b110% and delivers a Rated Power 4 kW output for versatile motor control. This converter incorporates a Unit Type Converter with a built-in brake chopper to handle regenerative energy and protect the DC bus. Active Cooling Mode heat dissipation panel ensures efficient thermal management in demanding industrial environments.

Installation and safety are paramount: the control must be bonded to the protective conductor before energizing and integrated with an emergency stop or start-inhibit circuit. Terminals for control voltages between 5 V and 50 V comply with IEC 60364-4-41, and the device maintains a leakage current exceeding 3.5 mA under operation. The drive presents a design code of 1 and carries a one-year warranty tag for reliable performance assurance. Shielded cabling is required when pairing with a variable speed motor to suppress electromagnetic interference and maintain stable heat dissipation panel operation.

Compact yet robust, the RD52.1-4B-004-P-NN-FW withstands global transport via recognized freight carriers and resists performance degradation at elevated ambient temperatures. Clearances above and below the unit must be maintained in the enclosure to support the passive heat sink and protect against condensation. Together, these features make the RD52.1 a dependable converter solution for precision motor-driven applications.
