Re: [CAD_CAM_EDM_DRO] Jerrys Power Supply.pdf

The transformers are 10 amps, the rectifier is 12 amps, so the weakest
link is the transformer.

If transformers are connected in series (adding), then voltage out is
the sum of the voltages. The current is that of the lowest rated
transformer. When connecting in parallel, the current is the sum of the
currents, The voltage of all transformers in parallel should be the
same, and that will be the output voltage.

The schematic doesn't show any fuses. I sprinkle them about liberally.
One on each input leg of the transformer, one on each output leg of the
transformer, and one on the DC in for each driver.

Regards,
JJ
