DC Ceiling fan
And they are the only ceiling fans that run completely silently, 1.5 db ... Of course, at higher speeds there is a normal wind noise.
Another special feature is the remote control, which is automatically supplied to each fan. The functions of this remote control are 5-6 levels, light on / off and forward / reverse. The 1st stage is a slow-motion stage, the fan runs at 25 - 55 rpm depending on the diameter.
It is also perfect that summer and winter operation - i.e. the flow and return of the ceiling fan - can now be set directly using the associated remote control.
Connection 230 V / 50 - 60 Hz: DC fans should not be supplied with continuous current, as the receiver can then be easily damaged. DC fans should also not be connected to 5-core cables. Here is the explanation :
DC receivers are essentially small computers.
The Problem: When you flip a hard switch that sends direct power to a receiver that is already "ON" or under load, you get a massive inrush current.
The Result: Without the soft-start protection often built into dedicated remote systems, this spike can fry the delicate MOSFETs (metal-oxide-semiconductor field-effect transistors) that control the motor’s phases.
If several DC ceiling fans are to be installed in a room or in a house, it is advisable to select the frequency of each individual ceiling fan differently so that not all ceiling fans are controlled together. If this is desired, it is of course also possible.
