The operating temperature is the range of ambient temperature within which a power supply, or any other electrical equipment, operate in. This ranges from a minimum operating temperature, to a peak or maximum operating temperature, outside which, the power supply may fail.

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

Operating frequency is the frequency at which the communications are being made with the total bandwidth occupied by the carrier signal with modulation. Usually bandwidth of the antenna will be wider than the bandwidth of the signal so that more than one center frequency the antenna can be put in to effective use.

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.

Line regulation is the ability of a power supply to maintain a constant output voltage despite changes to the input voltage, with the output current drawn from the power supply remaining constant.

Load regulation is the capability to maintain a constant voltage (or current) level on the output channel of a power supply despite changes in the supply's load (such as a change in resistance value connected across the supply output).
