Direct current fans

Ceiling fans with economical direct current technology 

When it comes to operating on an energy-saving and therefore economic level, direct current ceiling fans offer a lot more advantages than models with classic alternating current supply.
The operating voltage of the used electric motor is 24 Volt for most models. In order to function when connected to 230 Volt supplies, the models are equipped with an integrated converter that reduces the incoming 230 Volt AC voltage to the 24 Volt DC that the electric motor needs.

Depending on the used technology, the conversion is either carried out by a transformer with subsequent rectification or in an all-electric manner. When the device is primarly designed for operation with 24 Volt, the corresponding conversion needs to be provided on-site. This comes in handy, for example it is possible to operate several 24 Volt models at once with a central and sufficiently installed converter - a very efficient way of ventilating wide areas.
Furthermore it should be noted that direct current fans with 24 Volt are also suitable for use with solar energy or photovoltaic systems, provided that the system is designed for the same voltage. 

Now the advantages of ceiling fans with direct current technology: Saving energy is clearly the main aspect. Compared to classic alternating current fans these devices consume about 60 percent less power. Fans with alternating current motor use up ca. 50 to 80 Watt on average, whereas the direct current motors need only about 20 to 30 Watt - while performing with the same rotation speed and air flow.
Another advantage of the direct current fans is the whisper quiet and smooth operating - motor sounds are almost not noticeable.

Many models allow for the motion direction of the motor to be changed, switching between summer and winter operation. With the help of different extension rods and the right cable extension set out direct current fans can be adapted to the needed installation height.
In a nutshell, ceiling fans with direct current technology are a real alternative to standard devices.
