The maximum current that can be supplied to the load.

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.

That power available at a specified output of a device under specified conditions of operation.

The maximum output power = the maximum output current × the rated output voltage

Isolation voltage refers to a test of the ability of an insulator to minimize the flow of electric current with a high applied voltage.

Radiation hardening is the process of making electronic components and circuits resistant to damage or malfunction caused by high levels of ionizing radiation, especially for environments in outer space (especially beyond the low Earth orbit), around nuclear reactors and particle accelerators, or during nuclear accidents or nuclear warfare.

RoHS means “Restriction of Certain Hazardous Substances” in the “Hazardous Substances Directive” in electrical and electronic equipment.
