DESCRIPTION
The PSPW250 series of 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 60950-1, 2
nd
Edition, CSA 22.2 No.60950-1-07, and NEMKO
EN60950-1:2006+A11 safety approvals. This series is RoHS compliant and meets CE, FCC Class B, CISPR22
Class B, and EN55022 Class B EMC standards. Models are available in both open frame (Type O) and U-chassis
(Type U) designs.
