Product Description

The Bosch RD51.1-7N-015-L-NN-FW is a modular drive controller. Drives from the RD51 product line support multiple additional functions. These functions allow drive adaptation to customer requirements. If required, customers can order addition functions for the RD51.1-7N-015-L-NN-FW drive. Bosch develops multiple firmware versions for RD51 drives. The firmware versions support different features. For this reason, customers need to specify the firmware version for their controller separately from the hardware. The RD51.1-7N-015-L-NN-FW drive is inverter-based. The input voltage range of the inverter is 530 to 670 Volts DC. Inverters are devices that convert DC voltage input to AC voltage output. Output power of the RD51.1-7N-015-L-NN-FW at 4 kilohertz pulse frequency is 15 kilowatts. Output power of the drive at 8 kilohertz pulse frequency is 11 kilowatts. Output current of the drive at 4 kilohertz pulse frequency is 30 Amps.

Output current of the drive at 8 kilohertz pulse frequency is 25 Amps. Rated output of the RD51.1-7N-015-L-NN-FW at 4 kilohertz pulse is 20 kVA. Rated output of the drive unit at 8 kilohertz pulse is 16 kVA. Environmental class of the drive unit is 3K3 as per DIN IEC 721-3-3. The drive delivers rated output when the temperature of the surrounding air is between 0 and 40 degrees Celsius. Bosch has developed the drive for forced air cooling. The cooling air requirement is 0.05 m³/s. The radio interference suppression level of the drive is A1 as per EN 55011. Size class of the RD51.1-7N-015-L-NN-FW is B and the ingress protection rating is IP20. The shipping weight of the drive unit is 11.3 kilograms. Only trained technical personnel should plan and implement drive handling, installation, operation, and maintenance.
