Sola/Hevi-Duty IC202

Current rating is the maximum current that a fuse will carry for an indefinite period without too much deterioration of the fuse element.

The rated output current is the maximum load current that a power supply can provide at a specified ambient temperature. A power supply can never provide more current that it's rated output current unless there is a fault, such as short circuit at the load.
