I was wondering if I can use two of those banggood psu kits together to make a dual channel power supply with only one transformer.
Here is a link of the psu in question:
http://www.banggood.com/0-30V-2mA-3A-Adjustable-DC-Regulated-Power-Supply-DIY-Kit-p-958308.htmlI know the parts aren't the best for the claimed specs etc but I won't be using this for any critical or current hungry tasks and I thought It'd be a good a idea to chain two of these together.
So I have fairly big transformer with many taps.
Measuring the tap voltages (no label on the traffo itself) I can get 24V (2x12 center tapped ) and from another secondary I can get 50V (2x24).
That's also 24V when probing the center tap and one of the 50V terminals.
The two secondaries are isolated from each other (I get infinite resistance between any of their pins)
Given the size/weight of the transformer I think that both of its secondaries can handle the amperage I plan to use the PSU for.
(I think about 1.5A max ,only for powering small projects,low current electronic devices,testing things etc)
I've already bought one kit and it's working nicely with the 24V outputs of the trafo.
So ,my question is:
What would be the best way to connect these kits together with this transformer?
A} Connect the two of them in parallel with the 24V taps?
I think this should forbid connecting the two supplies in series though because I would essentially be shorting the transformer's secondaries, no?
B} Connect one kit to the 24V tap and the other with the 50V tap?
I think that could be the safest bet since the 24 and 50V secondaries are isolated from each other.
Is that the closest to having two separate power supplies?
Any hidden traps?
or
C}
Connect them in series?( one 24V to one AC input of the first supply and then the other to the same input of the second supply and then the two remaining AC inputs together?
I'm not sure if I have thought or even understand C correctly so I don't know if it's even a valid option..
