DESCRIPTION
The PSME1200 series of medical AC/DC switching power supplies provides 1200 Watts of output power in
a 10.256” x 5.000” x 2.500” enclosed case. This series consists of single output models ranging from 12VDC
to 60VDC with a universal input voltage range of 90~264VAC (127~370VDC). Standard features include
high efficiency up to 93%, programmable output voltage and output current, remote on/off, and power OK
signal. This series also has over temperature, over voltage, and over load protection. These supplies also
feature a low leakage current of less than 300μA (earth) and less than 100µA (patient) at 264VAC and are
designed to withstand 4000VAC input to output isolation (2 x MOPP). All models are RoHS compliant and
have ANSI/AAMI ES60601-1, TUV EN60601-1: 2006, and IEC60601-1 medical approvals.

NOTES
1. Ripple & noise is measured at 20MHz limited bandwidth and using a 12" twisted pair-wire terminated with a 0.1µF & 47µF capacitors in parallel.
2. For voltages near the low end of the input voltage range, see the derating curve for the power supply output rating.
3. When in parallel operation only one unit might operate if the total output load is less than 5% of the rated load condition.
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.
