help please with toroidal transformers selection

[Tom J]

Thanks Rob I know all that from college & university.
My power supply for drivers includes capacitors 2x10.000uF so can deal with back EMF well, that is why I am so concern about leaving spare 5V before max operating voltage.
I know some guys go for max like 1-2 volts off.
My 1st panel 3 years ago had 720VA trafo with soft start and stabilized 12v for BOB lpt1.



I am building another box 300x300 which is only High Voltage PSU and 24vDC

here are industrial PSU 24Vdc all stabilized



I need trafo to my 70VDC Leadshine EM705
60VAC after bridge and capacitors will be above 70VDC so have to get another one

I was asking for final dc voltage after rectifier and capacitors?
48VDC what ?VDC
50VAC what ?VDC
55VAC what ?VDC

Send the question to provider but no reply so far
Thanks
