Plugable system for supplying fan with DC voltage, includes second connection system which is connectable with plug connector part of fan

摘要

The plugable system (23) is designed with a first (27) and a second connection system (25). So that at the first connection system, cables are connectable with mains AC voltage and with the second connection system, an electrical connection is producible for the supply of a fan (20) with unipolar voltage or DC voltage. The plugable system (23) by means of the second connection system is connectable electrically and mechanically with a plug connector part (21) of the fan or the fan shell. The electronic circuit is designed in such a manner, that it is operable over a wide range of mains voltages, and essentially delivers the same DC voltage for the electric supply to the fan.
