3.1.2 Power Supply
The power rating of the supply may be chosen according to the desired operating point, maximum speed and
number of fans per supply see Figure 10, Figure 11 for continuous and peak power consumption respectively.
An optional input power limit may be set via Levitronix
®
Service Software or Modbus protocol. If set, actual
acceleration rate and/or maximum speed are reduced dynamically such that the specified limit is not exceeded
10 W tolerance). The dashed line in Figure 11 shows an example for 120 W at operating point with maximum
power consumption. Past 5000 rpm, acceleration rate is gradually reduced until maximum possible speed at
120 W is reached (around 10500 rpm, see also Figure 10).
It is highly recommended to evaluate power supplies under demanding operating situations like fast braking
from maximum speed and during power on and take-off of the fan rotor.
Table 4 shows a selection of power supplies tested at Levitronix
®
. Please note that only the general
functionality of the BFS-i06 in combination with the given supplies was tested, and no recommendations in
terms of reliability, efficiency, certifications, cost effectiveness or similar are given.

Table 4: Specification of tested power supplies
Note 1: Interface panel FIP-2.1 is available for quick connection of multiple fans, see section 4.3
The following power supplies are not recommended (insufficient recovery after fast braking):
TDK-Lambda RWS series, Cosel PLA / PJA series
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. These high inrush currents might disturb certain power supplies.
A peak value of 150 A with an I
2
t value of 2.9 A
2
s was measured by hot-plugging the BFS-i06 with 5 m cable
length to a 480 W power supply. It is therefore recommended to connect the bearingless fan to the power
supply before powering up the supply.
