All Emerson Network Power DCH5 series adapters have a universal 100 to 240 Vac input, enabling them to be used worldwide, and generate a regulated 5 Vdc output capable of delivering up to 1 A continuously. The adapters operate in constant voltage/constant current mode, and are intended for powering any USB peripheral device rated at 5 W or less requiring an external power source. Typical applications include small networking equipment, and powering or charging devices such as smartphones, tablets, digital cameras, portable gaming devices and e-book readers.
