Permalink: Emerson announces USB AC-DC power adapters

Emerson Network Power has launched the DCH3 series of wall-mounted AC-DC power adapters, featuring mini-USB connectors for their DC power output.

The adapters have a universal 100 to 254VAC input and generate a regulated 5V output, with a power capability of 3W.

They are designed to charge portable consumer electronic devices which need a 5VDC supply and use mini-USB connectors for their power input, including mobile phones and digital cameras.

A choice of three models are available, each one designed with a different input plug to suit a different geographical region.

The adapters are designed with safety and energy efficiency in mind.

They comply with the Energy Star Level IV efficiency standard. They have a very low safety ground leakage current of 10 µA maximum, and provide a constant voltage, constant current output.

Safety features include protection against over-voltage and short-circuit conditions, and integrated EMI filtering. Safety approvals include UL/cUL60950-1 and EN60950-1 VDE.

The adapters can operate in temperatures from 0C to +45C.
