Page 11: Power Supply
3.1.3 Inrush Current The BFS-i06 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. -
Page 12: Sound Pressure Level
3.2 Sound Pressure Level The sound pressure level emitted by the BFS-i06 strongly depends 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. -
