Engineering Information
3.1 Power Supply and Consumption
3.1.1 Power Consumption
Figure 8: Steady state power consumption vs flow and speed (DC input)
Typical values measured for BFS-i06.1
Figure 9: Peak power consumption during acceleration (DC input)
Typical values measured for BFS-i06.1 at operating point with maximum power consumption
Dashed line: example of optional input power limitation
•
Steady State Power Consumption: Depends on the actual speed, pressure, and flow. Figure 8
visualizes the steady state power consumption for different operating points.
•
Peak Power Consumption (short time): Occurs during acceleration and depends on the rotational
speed and the acceleration rate. Figure 9 visualizes the peak power consumption.
•
Power Supply Rating: Depending on the operating point, one power supply may be used to power
several bearingless fans simultaneously, or a supply with lower power rating may be used (see also
section 3.1.2).
