PSM250

The PSM250 series of medical AC/DC switching power supplies offers 250 Watts of output power with 17.1CFM forced air and 200 Watts with convection cooling. All models have a single output, a 90~264VAC input voltage range, and a power factor greater than 0.9. These units are also protected against short circuit, over load, and over voltage conditions. All models have UL/cUL 60601-1, TUV EN60601-1, and IEC60601-1:2005 (3rd edition) safety approvals. This series is RoHS compliant and meets CE, EN60601-1, FCC Part-18 Class B, and EN55011 Class B EMC standards. Models are available in both open frame (Type O) and U-chassis (Type U) designs.
