Meanwell SMPS voltage regulation, changing the Trimmer (LRS series)
Although you will probably void your warranty, if you measure all the R values around the Pot and the tap voltage Vref, you can reduce the voltage by adding a feedback resistor approx 4x the one from 24V Then the regulator will reduce the output to match Vref.
2.5 1.5 1.25 1V are common Vref voltages.
simulated here. Press the switch and adjust R to see results.


it comes with a +/- 15% adjustment range trimpot according to the range in datasheet.

I have done this before on laptop chargers. It is a standard tuning method.
You can solder directly to the nodes Pot and Vout with short leads.
If you can modify it without a trace and remove it, if it fails for some other reason, you might get warranty service. (Assuming no foul modification or ESD damage). But technically CE, UL and OEM do not permit selling it modified. But DIY for your own use, you take the risk of failure to follow these simple instructions.
