b maXX 5100 - Rectifier and regenerative feedback units

Energy costs often cover nearly 90 percent of the total life cycle costs of electric drives. Efficient power feed units that are simultaneously regenerative help to reduce the total costs of ownership.

Baumüller’s proven b maXX automation and drive solutions are extended by the b maXX 5100 series of rectifier and regenerative feedback units. The b maXX 5100 devices supply one or more power modules and enable the sinusoidal feedback of braking energy into the power supply.

Less power required thanks to energy-optimized power feed

The highly efficient b maXX 5100 mains inverter supplies the power modules with sinusoidal input currents. This prevents unwanted reactive power. Compared to conventional mains rectifiers, this means a lower connected load and a reduced power requirement, which in turn saves costs.

Energy-efficient feedback of braking energy into the power supply

Considering the energy costs, there are decisive savings opportunities for the user over the service life of the machine. Regenerative systems help to reduce energy consumption by not converting the braking energy into heat via a ballast resistor, but instead feeding it back into the power supply — which also benefits the environment.

The b maXX 5100 units are seamlessly integrated into Baumüller’s b maXX automation and drive solution. By realizing 3 different installation sizes over a power range of 36 kW to 200 kW, the user advantages of modularity and flexibility of the b maXX series are consistently implemented. System consistency is ensured both by adopting the housing technology and connection data and by integrating the parameterisation of the b maXX 5100 into the existing b maXX ProDrive operating software.

• Sinusoidal feedback of braking energy into the power supply
• Three installation sizes with 36 kW to 200 kW
• Overload capability for up to 120 seconds
• Current-controlled charging connection
