Hello again, this might be a bit of a far-fetched question, but is it possible to modify a 36v and a 48v power supplies to output 12v? Both power supplies appear to use the same topology, they both also have a dedicated 12v winding wired to the control chips, meaning that as soon as i change it so the main output is 12v, then the dedicated windings will not be able to output 12v, meaning it will not start up. However, if i were to then take the main output and tie it to where the dedicated 12v output would go, then it should be able to run fine?
Anyway here is a quick overview of both PSUs, the first PSU is a Genssi model S-350-36 rated 36V, 9.7A.
The main switching transistors are two J13009
The primary capacitors are two real-looking NCC CE 680uf, 230v
The control chip is a TL494CN with a LM358 op-amp
The secondary rectifier is a ESAD92-02S
The (main) secondary capacitors are two Samyong NHA 2200uf, 50v
The 12v secondary capacitors is one Tocon 47uf, 50v, and one NCC KY 4.7uf, 50v
And the second PSU is a Generic, model T-500-48, rated 48v, 10.5A, but it might be slightly overrated.
The switching transistors are two D13009K
The primary capacitors are two fake-looking NCC KMH 820uf 250v (they have a butterfly in the datecode, do i need to say more)
The control chip is a KA7500BD
The secondary rectifiers are 2 20JL2C
The (main) secondary capacitors are three Su'scon SK 1000uf, 50v
The 12v secondary capacitor is a yw 100uf, 35v
Any help will be appreciated. And if anyone is wondering why i need two high current 12 PSUs, the reason involves a lot of 12v LED strips.
And if 12v is too far-fetched, then would 24v work? I can still find most of the parts i need in that voltage.
