Fuse time current curves (I [amps] versus t [time]) should be consulted

for verification of the primary line fuse selection. The DC fuse should not

open as a result of normal inrush currents flowing at supply startup.

Inrush current is limited within most PFC modules to 5A peak

(3.54Arms) by an active inrush current-limiting circuit. Inrush current

duration (t) increases with increasing output capacitance (Cout) and can

be approximated by t = (50)x(Cout).

points in the circuit of Figure 3 are:

• F1: RoHS compliant S501-2-R fast-acting 5 x 20mm ceramic tube fuse

rated for 2A @ 250Vac
