Thanks guys, appreciate the advice

Think I should say that if you choose the top pic Jonathan drew you will be getting double the voltage of the 2 secondery ouput ratings IE: 2x24=48V but only half the rated Amps of both seconderys but if you wire have 48V seconderys and wire parallel you get the same 48V but double the amps.

No difference really has lower voltage seconderys have higher amps, roughly double, if the higher seconderys are double the voltage.!! . . . So 2 x 24Vac 12A seconderys can either give 48V @ 12A wired series or 24V @ 24A wired parallel. . . . So obviously 2 x 48Vac 6A seconderys wired parallel will give 48Vac @ 12A.

The 48Vac when rectified to DC will give roughly 68V IE: 48Vac x 1.4 = 67.2Vdc

Heres a pic of one (Big one) wired in parallel using 4 x 4700uf caps.!! ( Ignore the chocy block on the input that was a temp bodge.!)
Has you can see nothing too it. . Simplizzzzz.

48Vac @ 12A.

Didn't see the point of that...In short, the power has to stays the same, hence why I specified what power transformer to get as then so long as you wire it for the right voltage, the current will be correct by default.

Sent you a pm Jonathan regarding a build if you're up for it?

Yes I am. I'll sort it tomorrow - need to check what bits I have as I might already have everything you need.

Yep but I find folks under stand better when it's spelled out and the difference known.? He could have been wondering why or how 24V could give him 65+V.?

Just me being OTT maybe.?
