Converting the HP HSTNS PD29 to 13.8V, trying to fix the Over Voltage Protection circuit.
Check • #188 HSTNS-PD29 Over V... to see the real fix of the OVP
I keep getting asked questions regarding the OVP circuit and can it be defeated? Will it does not affect me as i just keep the output below it and it seems happy. But as there were a lot of questions i thought that a bit of investigation was required.
This video is the result of the first look at the components on the side board to see if I could find one that seemed to control the voltage trip point.
You will have to watch to see if this video has a successful outcome or just raises more questions.
I've not provided links to the datasheets are they all seemed easy to find on Google with just entering their part numbers.
Please comment if you think that more investigation is required or you know where more information on this PSU can be found.
