ATX Power-Supply
Version 2
Deutsch
Dies ist meine Neuauflage des früher schon einmal veröffentlichten ATX-Netzteils für die Werkbank mit einstellbarer 4ter Spannung. Das erste Design war irgendwie doch nicht so das wahre und hatte eindeutig zu dicke Wände. :)
Die neue Variante ist diesmal komplett mit Einhausung des ATX-Netzteils. Die Schaltung bleibt die selbe.
Ihr braucht neben Schrauben und Muttern:
4 pcs. V/A Meter DC100V 10A KWS-DC121 , 45x26mm (wish.com)
1 pcs. Mainswitch 19x13mm
1 pcs. 200W 8A DC-DC Step-Down Converter 61x41mm incl. Poty and Knob (wish.com)
4 pcs. Banana-Plug black
4 pcs. Banana-Plug red
1 pcs. Banana-Plug blue (for -12VDC)
1 pcs. 10Ohm resistor (greater than 2.5W) if Dummy-Load is needed
4 pcs. PCB with OpAmp LM358N and Shunt
Die Beiden Teile für die ATX-PSU Einhausung könnt ihr nach dem Druck zusammenkleben, braucht ihr aber eigentlich nicht unbedingt.
Die Front wird mit den beiden hinteren Teilen durch 4 kleine Holzschrauben M2 oder M2,5 verschraubt. Der Spannungsregler wird mit dem Poty und 4 M3 Schrauben (2 reichen auch) befestigt. Die übrigen Teile werden eingeklippt oder mit Kabelbinder fixiert.
Die 4 Leiterplatten mit LM358 werden benötigt um das Messgerät in die Positive Versorgungsleitung einbinden zu können, da die Messgeräte ihrer Konstruktion folgend ohne die zusätzliche Schaltung nur in der negativen Leitung einer Last eingebunden werden können. Das ist aber nicht zuträglich bei mehreren positiven Versorgungsspannungen mit gemeinsamen COM.
Schaltung für Zusatzplatine lade ich in den nächsten Tagen hier hoch, sobald ich sie sauber gezeichnet habe.
Wenn es dir gefällt:
Hoffe jemand kann es gebrauchen.
Wenn es jemand baut, dann bitte unbedingt ein "Make" posten, ich will wissen was Ihr daraus macht!
:)
Bleibt gesund!

This is my new edition of the previously published ATX power supply for the workbench with adjustable 4th voltage. The first design was somehow not the real thing and clearly had too thick walls. :)
This time, the new variant is complete with housing for the ATX power supply unit. The circuit remains the same.
In addition to nuts and bolts, you need:
4 pcs. V / A meter DC100V 10A KWS-DC121, 45x26mm (wish.com)
1 pcs. Mainswitch 19x13mm
1 pcs. 200W 8A DC-DC Step-Down Converter 61x41mm incl. Poty and Knob (wish.com)
4 pcs. Banana plug black
4 pcs. Banana plug red
1 pcs. Banana plug blue (for -12VDC)
1 pcs. 10Ohm resistor (greater than 2.5W) if dummy load is needed
4 pcs. PCB with OpAmp LM358N and Shunt
You can glue the two parts for the ATX-PSU housing together after printing, but you don't really need them.
The front is screwed to the two rear parts using 4 small M2 or M2.5 wood screws. The voltage regulator is attached with the Poty and 4 M3 screws (2 are also sufficient). The remaining parts are clipped in or fixed with cable ties.
The 4 printed circuit boards with LM358 are required to be able to integrate the measuring device into the positive supply line, since the measuring devices can only be integrated into the negative line of a load without the additional circuitry, following their construction. However, this is not beneficial if there are several positive supply voltages with a common COM.
I will upload the circuit for the additional board in the next few days as soon as I have drawn it cleanly.
If you like it:
Hope someone can use it.
If someone builds it, please post a "Make", I want to know what you do with it!
:)
Stay healthy!
