The Input Frequency refers to the frequency that mobiles and portables transmit on to access a Repeater.
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.
Semiconductor package is a carrier / shell used to contain and cover one or more semiconductor components or integrated circuits. The material of the shell can be metal, plastic, glass or ceramic.
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 actual voltage at which a circuit operates can vary from the nominal voltage within a range that permits satisfactory operation of equipment. The word “nominal” means “named”.
Output (I/O) Connectors are for attaching external devices, such as printers, keyboards, and displays, to the server.
No load power consumption is the electric power consumed by a battery charger when it is plugged into a wall socket but without the mobile phone or other battery device being connected.
