DESCRIPTION

The PSMP20 series of Medical AC/DC switching mode power supplies provides 20 Watts of continuous output power in a

3.5” x 2.0” x 0.76” open frame 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.
