Figure 8 visualizes the steady state power consumption for different operating points.
3.1.3 Inrush Current The BFS-i06 bearingless fan relies on the inrush current limiter of the power supply and does not have a built- in inrush current limiter. Therefore, high inrush currents may occur if the fan is directly connected to an already powered DC socket.
Note: Dimensions in mm 3.2.2 Mounting Proposals BFS-i06 fans can be adapted into many different duct systems and may be operated in parallel or series to achieve higher flow or pressure. This section describes a few of many possible mounting scenarios. For more ®...
Figure 12: Examples of mounting with self-cutting thread inserts (left) and through holes (right) 3.3 Sound Pressure Level The sound pressure level emitted by the BFS-i06 depends strongly on the installation, operating point, and rotational speed. It is recommended that customers measure the sound pressure level after installation of the fan in their setup during typical operation.
If other power supplies are used ® than the ones tested by Levitronix , it is highly recommended to test these under dynamic conditions (acceleration and deceleration of the fan up to maximum rotational speed).
