Just like the question asks...can I use just the power board from a PS1 board as a reversing unit to feed a DC motor? I have a QSI AC reversing unit, but without the bridge it's not helpful to me.
I was thinking I can just wire a bridge between the outputs of the AC reverser and the DC leads, but I'm nervous. All the bridges I see on the PS1 boards have huge diodes at each leg. I thought that's what the square bridge actually was...the diode pack internal to that square card-table looking thing. OR is the square thing just a heat sink?
Are the extra diodes related to other functions, or are they critical to completing the bridge circuit? (see photo below, the reverse unit and what I thought was the bridge rectifier
However, all the bridges on the PS1 boards go right through a diode on each leg. So I'm thinking the square thing is NOT a rectifier all by itself? (See yellow arrows below). Can I cut the bridge off of this board and hook it up to my other reverser, or just use the board as-is? I think it's too long which is why I'm interested in cutting it.
