New Products: Wall-mount ac-dc power adapters

The DCH3 Series of ac-dc power adapters uses mini-USB connectors for dcpower output and offers a choice of three models with different input plugs, to suit the region of the world in which they are used.

All three power adapters have a universal 100-to-254-Vac input and generate a regulated 5-Vdc output at 3 W. It meets Energy Star Level IV efficiency standards and has a 10-μA maximum safety ground leakage current. Each adapter features protection against overvoltage and short-circuit conditions, built-in EMI filtering, and safety approvals including UL/ cUL60950-1 and EN60950-1 VDE. They work over an ambient operating temperature range of 0 to 45°C.
