The DC Voltage ratings are the AC voltage values times 1.41 (usually rounded).
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.
This function will evaluate a given expression (or a value) against a list of values and will return a result corresponding to the first matching value. In case there is no matching value, an optional default value will be returned.
The current rating of a contact is defined as the current level that creates a certain temperature rise of the contact spring — usually 20°C or 30°C. Both electrical and thermal factors govern the heat created by the current.
