- modding the power supply to 35V
Danny showed me the DP30V3A – thus emerged the idea to „briefly“ build a tiny benchtop power supply that is powered directly by a wall outlet.
As I didn’t have access to a lasercutter for a while this project just collected dust.
I opted for the 36V version of the Qianson WX-DC2416 switching power supply as power source for the DP30V3A since it was the smallest 230V -> 36V power supply with enough amperage I could find at the time.
It does require a quick mod though because the DP30V3A can only handle 35V.
As you can see I placed a 47k multi-turn precision potentiometer in place of the R11 resistor (original value 20k).
This R11 resistor is part of a voltage divider that adjusts the output voltage.
