DESCRIPTION
The PSME20 series of Medical AC/DC switching power supplies provides 20 Watts of continuous output power in a 3.7” x
2.2” x 0.89” encapsulated PCB mountable package. This series consists of 5V, 12V, 15V, and 24VDC output models with a
universal input voltage range of 85~264VAC or 125~373VDC. These power supplies are protected against short circuit,
over load, over voltage, and brown-out (low AC input voltage) conditions and have an MTBF of 188,300 hours using MIL-
HDBK-217F. This series also has UL60601-1, TUV EN60601-1, and IEC60601-1 medical approvals. All models have been
100% full load burn-in tested and are RoHS and Energy Star compliant.

NOTES
1. Ripple & noise is measured at 20MHz bandwidth by using 12" twisted pair-wire terminated with 0.1µF and 47µF
capacitors in parallel.
2. Tolerance includes set up tolerance, line regulation, and load regulation.
3. The length of the setup time is measured a first cold start. Turning the power supply ON and OFF very quickly may lead
to an increase in the setup time.
4. The power supply is considered a component which will be installed into final equipment. The final equipment must be
re-confirmed that it still meets EMC directives.
