DESCRIPTION
The PSPWX150 series of AC/DC switching power supplies provides 120 Watts of output power with
convection cooling and 150 Watts with 30CFM forced air. This series consists of dual, triple, and quad output
models with a 90-264VAC input voltage range. These supplies also feature a high efficiency up to 80% and a
power factor > 0.9 at 230VAC. These supplies are also protected against short circuit, over load, and over
temperature conditions. The PSPWX150 series has UL60950-1, CSA 22.2 No.60950-1, Nemko EN60950-1,
and CB IEC60950-1 safety approvals. This series is also CE marked and meets EN55022 Class B, CISPR22
Class B, and FCC Part 15 Class B EMC standards. Both open frame and U-chassis mechanical options are
available for this series.
