PCB-Mount 5W AC-DC meets Medical Safety Standards
XP Power today announced the EME05 series of ultra-compact, single-output, 5-Watt ac-dc power supplies. Believed to be one of the smallest 5-Watt supplies on the market and available in either an encapsulated or open frame mechanical format, the EME05 measures just 1.4 x 0.94 x 0.69 inches, taking up minimal space in the end application.
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 4000Vac 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. This is suited for accommodating application start-up 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- to 264-Vac 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 degrees C and operate across a wide temperature range from -25 to +70 degrees C, the EME05 can be used in most environments without the need for any additional heat sinking or forced airflow.
The EME05 series is priced at $14.06 for 500 pcs orders and is available from Newark, Digi-Key, or direct from XP Power and come with a 3 year warranty.
