XMT 300 PC – A Look Under the Hood

Here are a few pictures showing the large printed circuit boards and components inside the Miller XMT 300 PC power supply.  You knew these were coming, right!

Underneath the main chassis are several massive heatsinks and four 80mm fans for cooling.  Duct work inside the power supply enclosure routes cool room air in thru the bottom lovers and exhausts the warm air out the upper lovers. All of the electrolytic capacitors are high-quality and the overall build quality appears to be very good.

And finally, here is a picture of the main output terminals on the XMT 300 PC that feeds +12V power to the distribution modules.  Notice there are six pairs of terminals for attaching the #6AWG cables. Each set of cables can support up to four independent power distribution modules/PCs.
