Hi Tom,

I used 750VA, 2x24v in series (close Clive, I know some use 2x25v but I think it tipped the voltage a bit high once rectified and smoothed etc. ? Can't remember. I get 72V unloaded so OK with that.)

Note that I went with the 10A Type D MCB in the end as the 6A tripped out on startup due to the inrush current (no soft start). It's been running fine since.

Thanks

I have both 720VA 2x30V 2x12A and 420VA 2x30 2x7A in two different application. All secondary winding have to be in phase (start 1st coil & start 2nd coil as one cable and end 1st coil with end 2nd as one cable)
I tried 4A type D MCB and was tripping out from time to time on 720VA - did not try bigger MCB, will do try on smaller 420VA.
I might get away from using soft start

Got recently 2x45V AC 500VA nad was tripping 4A type D MCB as well, will update with 6A or 10A type D when they arrive.
