Product Description

The Bosch RD51.1-4B-003-L-NN-P1-NN-FW is a three-phase universal drive system. It is part of the RD 500 series which is designed for motor control applications. The RD 500 series is specifically designed for control of induction motors and synchronous motors. The RD 500 series can be operated at two different pulse frequencies that are 4 kilohertz and 8 kilohertz. The drives are designed for connection to AC mains at nominal operation voltage range of 380 to 480 Volts AC with 10% allowed tolerance. Rated motor output for the RD51.1-4B-003-L-NN-P1- NN-FW is 3 kilowatts at 4 kilohertz pulse frequency and 2.2 kilowatts at 8 kilohertz pulse frequency. The output frequency is 0 to 250 Hertz at 4 kilohertz pulse frequency and 0 to 500 Hertz at 8 kilohertz pulse frequency. The output current is 7.5 Amps at 4 kilohertz pulse frequency and 5.8 Amps at 8 kilohertz pulse frequency.

Environmental class of the RD51.1-4B-003-L-NN-P1-NN-FW drive system is 3K3 as per DIN IEC 721-3-3. The ambient operation temperature range is 0 to 40 degrees Celsius. The cooling method is forced air cooling and the cooling air requirement is 0.03 m³ per second. Approximate weight of the RD51.1-4B-003-L-NN-P1-NN-FW drive is 6.5 kilograms. The IP 20 rated drive system is designed for indoor use and should be mounted in a control cabinet. The drive includes an integrated brake chopper with 1.5 kilowatts of continuous power output. The chopper peak power is 10 kilowatts for 1 second and its minimum resistance is 60 Ohms. The RD51.1-4B-003-L-NN-P1-NN-FW drive is commissioned with prompts on the operator panel with graphical display. The drive system can also be commissioned from a PC with RDwin programming software. This product can be shipped globally with a one year warranty period from Wake Industrial.
