DESCRIPTION
The PSMBU250seriesof class I medical AC/DC switching power supplies
provides250 Wattsof continuousoutputpower in a 5.00” x 3.00” x 1.46” open
frame package. Thisseriesconsists of single output modelswith a wide input
voltage range of 90~264VAC. Somefeaturesinclude highefficiency up to 94%,
2MOPP insulation, andshort circuit, over current and over loadprotection. All
modelsmeet FCC Part-18, CISPR-11, and EN55011ClassB emission limits.
Thisseries also has IEC60601-1 Edition 3.1,ES60601-1:2005(R2012),
CSAC22.2 NO. 60601-1:14, andEN60601-1:2006/A1:2013 safety approvals. All
modelsare RoHS2 compliant and have been 100% burn-intested.
