Individual devices, however, have relatively narrow operational frequency bandwidths, meaning a particular Power Transoner should be matched with the operational frequency of its intended application or load. Isolating Power Transoners transmit electrical signals, with step-up voltage transformation, from an input terminal to an output terminal, while providing electrical isolation between input and output terminals. Non-isolating Power Transoners are much like isolating devices in that they are very small and highly efficient, but they do not provide electrical isolation. Non-isolating Power Transoners are well suited for compact applications that require high voltage gain at fixed frequencies but do not require electrical isolation. These applications include electro-luminescent displays, fluorescent lights, HID lamps, flash camera lights, miniature lights, and certain power supplies.
Performance represented above is achieved under optimum conditions for the parameter being tested.
