I am thinking the 48v is unregulated supply, hence the 52v, the 5v if regulated then if it has a + & - terminal could be +5 and -5 to a common or C if there is one on this supply?

There is a terminal in the center of the 48v rectifiers terminal block that is marked with a C, which I assumed was common. What is so confusing to me, is that I keep thinking of DC current like a battery. It requires both + and - to power something. In this case, using + and - doubles the voltage.. Still no word from Antek. I will call in a few minutes.

Just got this from Antek. You were right about the unregulated power on the 48V and the regulated on the 5v. I'm still confused on the use of the + and C instead of + and - though.

The sheet explains a bit more, but the terminal layout does not appear to jive?
Normally + = pos voltage, - = is used for a negative supply, both of these would be +v or -v with respect to C or Common.

Ok, the good.. the bad... and the ugly....

The good: The power supply is now working exactly how it's supposed to.

The bad: I had an idiot using the multimeter, and he didn't have the switch set to DC voltage.

The ugly: That idiot is me.

I normally wouldn't tell a soul, but in the spirit of honesty, learning, and hopefully helping some else out of this situation, I decided to share. To make things worse, I only learned of my error on the phone with Antek when John (the tech) asked if I was using the DC setting on the multimeter.

That will do it!
Thanks for the update.
