Recommended) 18 AWG 18 AWG 18 AWG 3x18 AWG 3x18 AWG DESIGN CONSIDERATIONS Over Current Protection The converter is protected from short circuit and over current conditions. Upon sensing a short circuit or an over current condition the converter output will begin to ‘foldback’. Once the output has dropped to near zero volts, the output will shut off and after a short delay try to restart. This is called a ‘hiccup’ mode and this mode will persist until the short circuit or over current condition is removed. Over Temperature Protection The converter is protected from over temperature conditions Fusing The input to the converter is protected with a UL R/C fuse. This fuse is NOT user replaceable.
