Economically efficient power recovery

Lenze has unveiled the Smart Energy Recovery r700, said to take power recovery to new levels of economic efficiency, practicality and simplicity. Available in two power versions: 12/24 and 26/48kW it features a separation of supply and recovery paths, permitting their individual design and precision dimensioning customised to system needs as well as an efficiency of 98%.

Typical implementation areas include storage and retrieval units or other lifting and handling equipment, in which a relatively high amount of energy is accumulated as the load is lowered or on test benches, where the test piece energy has to be permanently discharged as a matter of principle. Neither converting braking energy into heat or storing it in the system are options in applications of this nature, so recovering the generated energy and feeding it back into the grid via the Smart Energy Recovery r700 is a practical alternative.

The compact Smart Energy Recovery r700 is claimed to recoup its costs in around a year, depending on the quantity of power recovered.
