Minimal space for 5W medical-spec off-line power provision

March 04, 2016 // By Graham Prophet
XP Power’s EME05 series of single output, PCB-mount, 5W AC-DC power supplies is presented as one of the smallest 5W supplies available; in either an encapsulated or open frame mechanical format, the EME05 measures 35.6 x 23.7 x 17.6 mm.

The EME05 is approved to the 3rd edition of the international medical safety standards EN60601-1:2006 and ANSI/AAMI ES60601-1:2005. The device provides a reinforced (double) insulation with 4000 VAC 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 VDC. A peak load capability allows up to 130% of the rated output power to be available for up to 30 seconds for accommodating application start-up.


The EME05 has universal input and offers full power across the complete input range of 90-264 VAC without any derating. All models employ 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 +50C and operate across a wide temperature range from -25 to + 70C, the EME05 can be used in most environments without the need for any additional heat sinking or forced airflow. The supplies are at Farnell element14 and Digi-Key, and regional distributors, or direct from XP Power and come with a 3 year warranty.
