Re: Heads Up for Power Supply deal...

Hi Carlos,
Good question, and I think that should be possible.
It is a switch mode supply, which means it has 100% isolation from the input, so that's the first thing solved.

When you do connect in series, you will have one of the power supplies (negative) connection effectively at half voltage, and
only need to make sure you never "ground" it...

Connections would be like this

Positive from Supply #1 become the 36 Volt connection

Negative from Supply #1 never consider this as ground !
| connect together
Positive from Supply #2

Negative from Supply #1 becomes the 0V connection

I expect already know all of this. Also remember the negative is often also part of the circuit board screw mounting holes, and
you need to isolate that #1 supply,
for example mount it on Nylon spacer.

It should work, no reason why it will not.

regards
Hans Wedemeyer
