The regeneration of braking energy into the grid enables considerable energy savings, especially if a machine is running in reversing mode. The infeed and regenerative units "B Maxx 5100" from Baumüller For the power ranges 36 and 64 kW, the energy generated during braking is fed back into the grid. Then the controllers only have to compensate for the resulting slight energy loss. The B Maxx 5100 can supply one or more power modules.
The B Maxx 5100 realize an automatic synchronization to the frequency of the supply network, resulting in a power factor cos (φ) equal to one. Compared to a resistive charge, their current-controlled precharge has some advantages: when the device is switched on, the charging time is monitored and faults are detected and reported. Troubleshooting is possible before starting up and damage to the machine or the drive is prevented. Due to the regulated charging current, the inverter is safe against short-circuits even with main contactor release. The problematic current peaks during switching on are prevented and the optimum DC link capacitance for the respective application can be selected.
The B Maxx 5100 are suitable, for example, for use in the handling, textile and packaging industries. They can be used for energy saving in all machines with multiple drives or wherever flexible expandability is required.
