The R911200660 (RD42.1-4R-026-L), part of Bosch Rexroth Indramat's RD42 series, is a power supply unit purpose-built for inverters with DC connection within REFUdrive 500 range. It has a nominal power rating of 26 kilowatts, and operates within a main connection voltage band of 380 to 480 Volts AC (three-phase). The unit comes without a brake chopper and necessitates a recommended 63 Amps fuse. The DC link voltage varies from 530 to 640V DC, with the standard DC current and one-minute peak DC current rated at 50 Amps and 75 Amps respectively. Depending on the AC input (400 or 480 volts), the unit's rated and peak output for 60 seconds range from 26-48 kilowatts.
Operating with an AC rated current of 45 Amps, the R911200660 (RD42.1-4R-026-L) boasts a near maximum power factor of 1 and losses at the rated output stand at 0.8 kilowatts. The power supply unit is fabricated for forced air cooling, with the required airflow noted at a minimum of 0.08 m3/s. According to DIN IEC 721-3-3, the this device falls under the 3K3 Environmental class. Furthermore, it adheres to A1 suppression level as per EN 55011 / EN 61800-3 standards and guarantees IP20 degree protection as per EN 60529. Utilization and maintenance of the R911200660 (RD42.1-4R-026-L) should only be undertaken by trained personnel due to its intricate technical construction.
