DESCRIPTION
The PSMBU81 series of Class I medical AC/DC switching power supplies provides up to 80 Watts of continuous output
power in a compact 5” x 3” x 1.1” open frame package. This series has single output models with a wide input voltage range
of 90~260VAC. These power supplies have active power factor correction, an internal EMI filter, and input surge voltage,
over load, and over voltage protection. All models meet FCC Part-18 Class B and CISPR-11 EN55011 Class B Emission
Limits. This series also has ANSI/AAMI ES 60601-1: 2005 (UL/cUL 3rd edition) and EN 60601-1:2006 (TUV/T-mark 3rd
edition) safety approvals and also meets new CE requirements. All models are RoHS compliant and have been 100% burnin tested.
