HSTNS-PL28 to 13.8v mod?

[Fizfi]

HSTNS-PL28 Does anyone have knowledge about the voltage adjustment for this power supply?

I couldn't find anything specific to this model online and the control PCB looks quite different to the many videos I have seen regarding adding or removing resistors for the other various models. There are only 2 potentiometers and the one to the right only gives minimal adjustment up to about 12.32v.

Any advice or pointing to other resources much appreciated! This PSU seems to be made by LiteON and original p/n is PS-2461-7C-LF

Hi.
I have found a way to rise voltage for PL28.
https://aijaa.com/SesQtn
Just replace 0ohm to 470ohm resistor or 1k trim pot.
https://aijaa.com/VxUAjd
470ohm resistor gives about 13.3v.

Ovp kick in 13.5 - 13.6v

Im still looking for how to get ovp higher and i think it can be found other board.

Now i found a way to rise ovp for HSTNS PL-28.
Mod works at least rev5 to rev14..

I have tested psu and it works fine at 14.5v .
I loaded psu with 22A current on/off without any ovp kickoff.

I can make intructions soon.
