Product Description

The REFUdrive 500 system is one of Bosch Rexroth's sophisticated product offerings, including a wide range of industrial control products. Several models of drive control systems, such as the RD51 voltage frequency control units, are part of the REFUdrive 500 series. Pumps, extruders, ventilators, centrifuges, moving gears, and conveyor belts are all examples of applications that benefit from voltage frequency control drive systems. RD51 units are typically used to oversee the operation of electric motors. The RD51.1-5B-007-L-NN-FW is a member of this series, and it is equipped with an RD42 power supply module. It features a three-phase supply voltage of 500 Volts (±10 %). It shares many characteristics with other Bosch Rexroth products, including a cutting-edge hardware architecture, and it is classified as an IP 20-protected unit.

The RD51.1-5B-007-L-NN-FW is equipped with an internal brake chopper, which provides a continuous braking power of 0.1 kW by design. This unit utilizes a forced air circulation cooling technique, which requires a cooling airflow rate of 0.03 m³/s. A clean and moisture-free environment is necessary to store RD51.1 units, with environmental temperatures maintained between -25° C and +70° C.

The operational versatility of the RD51.1-5B-007-L-NN-FW, as with other RD51 units, is a distinguishing feature. In addition, it is operable at PWM frequencies spanning 4 to 8 kHz, with an incremental step size of 4. With an output power of 7.5 kW at 4 kHz, this converter drive control unit can operate in the frequency range of 0 to 250 Hz, with a rated current of 14 Amperes. 5.5 kW of output power and a rated current of 10 Amperes are achieved at 8 kHz PWM frequency. This product can be shipped globally with a one year warranty period from Wake Industrial.
