The rectifier section is supposed to be separated and high power diodes mounted as in a picture below (they can be attached directly to a chassis for heat dissipation, isolation pads needed). The board is designed mainly for 3 pin rectifiers, but will work with other diodes packages as well. Here's MUR3060:

Hi Peter. Is there any reason why would one use a such a diode? I haven't used it before but I believe you only need 2 to make a bridge. In your photo, you used 4.

Thank you for the reply

Possibly?? Paralled, to keep the current level and not push all the current through a single pair, even tho they can handle 36amp's.

With those PS boards you can't use them in parallel, I use only one half of each diode. But you can still wire them in parallel through additional jumpers.

You cannot use only two to build a bridge, as those are common cathode type only; you would need three.

I wanted to make the options for all diode type, including 3 pins type.
