Typical values measured for BFS-i10.1 at operating point with maximum power consumption
•
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.
