Selection and Installation
Match the output voltage to your load, and allow for its continuous current and start-up demand. Follow the manufacturer's derating curves: the maximum output is not available at every input voltage or ambient temperature. Adjusting the output voltage does not increase the permitted output power or current.
This is a component power supply, not a consumer plug-in adapter. Mains wiring should be carried out by a qualified person in a suitable protective enclosure. Disconnect input power before connecting wires, follow the marked terminal assignments and protective-earth requirements, and keep ventilation paths clear. The isolation figure is a test rating, not a continuous operating voltage.
