Sounds like a lot of work. Have you considered buying another Astron supply
and operating them in series?

Astron supplies can be used in series (double the voltage) and some in
parallel (like the PS-50, double the current).

I have been considerring modify an Astron 30 amp power supply to work
at 26 volts. I was thinking maybe I could do this by changing the half
bridge rectifier to a full bridge unit. Replacing the caps and
modifying the regulator circuit. I want to use the power supply to
power some 24 volt equipment and also maintain the charge on a 24 volt
100 amp/hr battery. I shamefully admit that I havent done much
research on doing this but was hoping someone else already had and
could save me some work.
