Device for feeding an actuating drive that can be driven wirelessly
An actuating drive ( 60 ), that can be fed by a battery ( 6 ), for an actuator ( 5 ) comprises a drive unit ( 61 ) for operating the actuator ( 5 ), and a control unit ( 62 ), capable of communicating with an external station ( 70 ) in a wireless fashion, for controlling the drive unit ( 61 ). The control unit ( 62 ) can be fed via a voltage regulator ( 64 ) connected to the battery ( 6 ), while the drive unit ( 61 ) is directly connected to the output voltage (U B ) of the battery ( 6 ). The energy consumption of the actuating drive ( 60 ) can be optimized in order to achieve a long service life for the battery.
