They are putting 2 LM338 voltage regulators in series which
allows you to draw 10amps instead of just 5amps. You could take your "Power Supply -
Variable" and replace the U1, R1, and R2 with the "Adjustable 10-A
Regulator" and then you could draw 10amps instead of just 5amps. Of course you would
have to replace the T1 with a 24V @ 10amps and you would also have to change at least C1
to I am guessing double it's current value. You might also have to change the other
capacitors. |
