The PFE Series includes six standard PFE300S (rated at 300 watts) and PFE500S (rated at 500 watts) models, where the “S” stands for “Simple Function Modules”. These models are fully regulated and are available with output voltages of either 12V, 28V and 48VDC.  The modules have a nice adjustment range as can be seen in this slide.  For example, the 28V unit can easily be adjusted to 24 volts and the 48V unit can provide 56 volts if desired.  The maximum operating base plate temperature for these PFE modules ranges from +85 degrees C to +100 degrees C and the modules can be mounted to cold-plates or metal structures for conduction cooling. These modules have standard full brick dimensions.
