XP Power announced the EME05 series of ultra-compact, single-output, 5 Watt AC/DC power supplies.

Believed to be one of the smallest of its kind on the market and available in either an encapsulated or open-frame mechanical format, the EME05 measures just 35,6 x 23,7 x 17,6 mm, taking up minimal space in the end application.

The product range is approved to the 3rd edition of the international medical safety standards EN60601-1:2006 and ANSI/AAMI ES60601-1:2005. It provides a reinforced (double) insulation with 4000 V a.c. input / output isolation and two means of patient protection (2 x MOPP).

The convection-cooled series provides eight single-output models covering all the popular nominal outputs from 3,3 to 48 V d.c. A peak load capability allows up to 130% of the rated output power to be available for up to 30 seconds. This is ideal for accommodating application startup where a higher load is required for a relatively short period. This approach allows a designer to save valuable board space and cost rather than having to specify a higher rated and potentially larger power supply in order to meet peak loads.

The EME05 has universal input and offers full power across the complete input range of 90 - 264 V a.c. without any derating. All models offer Class II construction so no earth/ground connection is required. The units meet the EN55011 Class B EMI standard for conducted and radiated emissions. No additional filtering components are required, saving PCB space and BOM costs.

Capable of delivering full power up to +50°C and operating across a wide temperature range from -25°C to +70°C, the EME05 can be used in most environments without the need for any additional heatsinking or forced airflow.
