AC Line Fuse
The power supply has one line fused in the single line fuse on the line (Hot) wire of the AC
input. The input fuse is a slow blow type. AC inrush current does not cause the AC line fuse to
blow under any conditions. Not all protection circuits shall cause the AC fuse to blow unless a
component in the power supply has failed. This includes DC output load short conditions.
