RD51.1-4N-030-L-D1-FW

Product Description

The Bosch RD51.1-4N-030-L-D1-FW is a drive control device with V/f characteristic control. It is based on an AC converter. The converter voltage rating is 380 to 480 Volts AC (three-phase). The drive converter does not include a brake chopper. Motor output rating of the RD51.1-4N-030-L-D1-FW under specified ambient conditions at 4 kilohertz pulse frequency is 30 kilowatts. Additional technical data for 4 kilohertz pulse frequency are as follows: 56 Amps rated current, 73 Amps peak current for 60 seconds, 95 Amps peak current for 1 second, 112 Amps peak current for 0.5 seconds, 37 kVA rated output and 48 kVA peak output for 60 seconds. Motor output rating of the RD51.1-4N-030-L-D1-FW under specified ambient conditions at 8 kilohertz pulse frequency is 22 kilowatts.

Additional technical data for 8 kilohertz pulse frequency are as follows: 43 Amps rated current, 55 Amps peak current for 60 seconds, 72 Amps peak current for 1 second, 85 Amps peak current for 0.5 seconds, 28 kVA rated output and 36 kVA peak output for 60 seconds. The cooling method employed for power dissipation is forced air cooling. Air flow rate of 0.1 m³/s or more is required for proper heat dissipation. Environmental class of the RD51.1-4N-030-L-D1-FW drive is 3K3 as per DIN IEC 721-3-3. The operating temperature is 0 to 40 degrees Celsius. Output of the RD51.1-4N-030-L-D1-FW derates at higher temperatures. The RD51.1-4N-030-L-D1-FW drive supports two additional functions: 24 Volts DC standby power and connection for RZC01.1-XT with NAMUR terminal strip. Firmware for the RD51.1-4N-030-L-D1-FW drive is ordered separately. Degree of protection offered by the drive housing is IP20. The drive mass is 36 kilograms. Qualified and experienced technicians should install the drive and other equipment. This product can be shipped globally with a one year warranty period from Wake Industrial.
