Product Data Sheet 2218F/2TDHO After 4 failed start-ups there is an extended timeout t5 of 40s.
Product Data Sheet 2218F/2TDHO Running current @ 48 V (I = 200mA/div ; t = 1ms/div) Internal Fuse: Littelfuse NANO2(R) FUSE; Very fast acting 451 Series; 3,5 A (Art.-Nr.: 045103.5MRL) Inrush current limiter: This fan is equipped with an inrush current limiter to reduce the charging current of the internal capacitor. This circuit delays the start-up of the fan by 4 s after connecting it to the supply voltage.
