The Bosch R911200401 (RD51.1-4N-030-L-D1-FW) is an AC converter-based drive controller featuring V/f characteristic control. It has a converter voltage rating of 380 to 480 Volts AC for three-phase operation. Notably, it does not include a brake chopper. Under specific environmental conditions at a 4-kilohertz pulse frequency, the device provides a motor output rating of 30 kilowatts. Its rated current is 56 Amps and peak currents range from 73 Amps for 60 seconds, to 112 Amps for 0.5 seconds. At 8 kHz frequency, the motor output rating is 22 kilowatts. Power is dissipated through forced air cooling, with an air flow rate of 0.1 m3/s necessary for effective heat dispersion. The R911200401 (RD51.1-4N-030-L-D1-FW) drive operates under the environmental class 3K3 according to DIN IEC 721-3-3, with a functioning temperature range from 0 to 40 degrees Celsius. Additional features include 24 Volt DC standby power and a connection for RZC01.1-XT with a NAMUR terminal strip. The housing offers IP20 protection and the device weighs 36 kilograms.
