*) This fan has an undervoltage and overvoltage control circuit integrated which turns the motor off if the voltage is out
of range.
First locked rotor off time is reduced to 3 seconds.
This fan has a startup delay of 2 seconds after applying supply voltage.
Note to inrush current:
The internal electrolytic capacitors 2 x 220uF/75V have an inrush current limitation, the remaining peak depends on
ceramic capacitor 2,2uF and EMI-filter.
Start-up current at 48,0 V; I=500mA/Div, t=2s/Div
