Emerson Network Power DCH5 USB wall mount AC-DC adapters

A range of 5 W USB wall mount AC-DC adapters, the DCH5 series, is based on an all-in-one design, which eliminates the need for dedicated power cable attachments and connectors.

Instead, one side of the adapter plugs into the AC supply and the DC output is made available via a standard USB type A receptacle on the opposite side.

The series has a universal 100 to 240 VAC input and generates 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.

There are four models featuring different AC input plugs for use in the US, Europe, Britain and Australia.

All models use the latest switch-mode power conversion and meet level V of the Energy Star international efficiency standard for consumer devices.

The adapters have a low safety ground leakage current of 20 µA maximum. Protection against fault conditions includes latching overvoltage, output short-circuit with auto recover and overload protection to less than 1.5 A.

They have a built-in CISPR 22 Class B EMI filter and meet the EN55022 Class B and FCC Part 15 Level B EMC standards for conducted noise and the EN55082-1 standard for electromagnetic susceptibility.
