40-60W Single, Dual and Triple Output
Isolated DC-DC Converters
The 40 and 60W rated board mounted PXF DC-DC converters feature 4:1 or 2:1 input ranges in a 2 x 2” (50.8 x 50.8mm) industry standard package. The
series is certified to the IEC/UL/CSA/EN 62368-1 safety standards and have six-sided, shielded metal cases for reduced radiated noise. The output volt-
age on the single and dual models can be adjusted by +/-10%. All converters in the PXF series have remote on/off.

Notes
See website for detailed specifications, test methods and installation manual
(1) With an input filter capacitor (Nippon chemi-con KY series, 220μF/100V)
(2) Maximum output deviation is 10% inclusive of remote sense and trim
(3) Load regulation for triple output: Main output:10-100%, with 10-100% balanced load on auxiliaries. Auxiliary outputs: 10% to 100% balanced on all outputs
(4) Cross regulation for dual output: asymmetrical load 25% / 100% full load. Cross regulation for triple output: Main output 100% load, auxiliary 100%, other auxiliary 25% to 100%
Auxiliary outputs: main output 100% load, auxiliary 100%, other auxiliary 25% to 100% or main output 25%, auxiliary 25%, other auxiliary 25% to 100%”
(5) Measured with a 20MHz bandwidth oscilloscope across a 0.1uF/50V MLCC
(6) Dual and Triple output models require a minimum load of 10% on the output to maintain specified regulation. No load operation will not damage the device
(7) If remote sense is not being used, the +Sense and - Sense should be connected to their corresponding outputs; +output, -output
