<p>The drive (1) has a speed reduction drive connected downstream to a rotational direction reversible electric motor. An energy supply device (5) has a power connector connected with a network through a power supply device (8), and transforms network-side input voltage into output-side small voltage. An isolation transformer or a transmission unit is provided for galvanic separation between a network-bound input side and a small voltage-bound output side for operation of the drive. The power supply device has an auxiliary voltage source formed as a miniature switch-mode power supply. A radio- or infrared receiver is provided in a housing for controlling the power supply device.</p> |
