I saw this switching power supply on eBay and wanted to see if could be modified to run 14.5 volts before the blocking diode was add and this switching power supply seems to have no issues doing this
I did recap the switching power supply except the the main filtering capacitors and I managed to break the selector switch for the voltage setting but just jumped it
One note I used 25 volt capacitors on the output side of this power supply because they used 16 volt capacitors and because I am running the voltage up a little bit higher 12 volts to 14.5 volts there would have been very little head room for the voltage on the output capacitors
One other note the ground rail that is also metal housing ground runs in between the hot side and the cold side of this switching power supply board
One other note the ESR values of capacitors less than 100uf were any where from a little bit high to in some cases doubled or tripled in value compared to a new capacitor
This switching power supply had some wire connectors that were wired wrong the “+” had black wires hooked to it and “-“ had red wires hooked to it I will use them in another project
I have one question would this switching power supply put out 30 amps of current it has a cooling fan and the temperature sensor is in the choke coil
I would post the link to where to buy one but the seller only has one left and I trying to buy the last one
