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.
the variation of output frequency of a crystal oscillator due to external conditions like temperature variation, voltage variation, output load variation, and frequency aging.
the amount of capacitance measured or computed across the crystal terminals on the PCB. Frequency Tolerance. Frequency tolerance refers to the allowable deviation from nominal, in parts per million (PPM), at a specific temperature, usually +25°C.
A phase of operation during the operation and maintenance stages of the life cycle of a facility.
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.
the maximum allowable deviation from the nominal crystal frequency at a specified temperature, usually 25℃. The recommended frequency tolerance of the crystal over the manufacturing process is ±50 ppm.
