You could probably do it by changing one or two feedback resistors. Assuming it is a switchmode device, there should be a PWM regulator/controller IC. This IC will incorporate an error amp. Usually, one pin will be connected to an internal reference voltage, while another will…
Read the full replyAnyone know how to modify this power supply for different voltages? There's no potentiometer on the board.

You could probably do it by changing one or two feedback resistors. Assuming it is a switchmode device, there should be a PWM regulator/controller IC. This IC will incorporate an error amp. Usually, one pin will be connected to an internal reference voltage, while another will connect to the output via a resistive potential divider. Tell us the part number of this IC and we can then advise you how to proceed.
