Thank you for this video, I needed a power supply for maintaining vehicle voltage above 13.5v with the ignition off. Used the 5.1k and 5.6k and was able to get it dialed in to 14.46v. full clockwise was below 14, and full counterclockwise was at least 15. I do not have a steady hand at all, so soldering was tricky for me, but I covered the area around the solder points with kapton tape and it worked great.
By far the BEST video for moding the HP PL11! Thanks for explaining what each resistor is doing and how each one will raise or lower the voltage. Now I have a power supply that can give me 60A to test car audio amplifiers I repair. I’ll be buying a second one to sync so I will have over 100A for testing big 2k amps. Thank you for your time making this for everyone. I just subscribed too!
The 3.3k and 5.1k are working like a champ with the supply set to 14.9v. Nice to see how to mod these as the DPS-1200SBA supplies are getting harder to find (cheap) and these are plentiful.
Nice video! I have had it on my to-do list to get some of these 1200W units and make a design with them. I have mostly used the 750W models and they work really well - even with the outputs connected in series. 👍👍👍 - The Innovati0n Lab.
Wonder what a good resistor combo for ham radio use would be with a target of 14.5V and having OVP kick in around 15.5V? My radio says the following. That way running at 14ish I wont have to worry about V drop on long transmits and don't have to worry if something goes wrong and the PS over volts. "The FT-857D radio requires 13.8 v +- 15% or 2V for a nominal range of 11.8 to 15.8V"
hmmm if you was to use say 4 of these together , using the voltage share pads, how could one hook up say a variable pot of 5k or 7 k outside to adjust overal voltage? i know the crowbar wont float with this kinda set up but would you be able to do this?
Excellent video. Im no pro . Just a hobbyists. So im doing 4 of these . I need to know about the load sharing .. If you can ,would you do a short on the load share function. I want to link 4 of these.
Hi, this is a very good method for such supply as I have applied same method but supply is being shut down on applying a little load from out put so plz must guide for fix it
Sir, do you have some advice on how I can find the volt share pin so I can probe around and find it myself on my flex slot PSU, it would be super appreciated if you would share how you identified it! And do those pins get connected in parallel between units? Finding official documentation on these PSUs is impossible. I bought the DPS-1400BB flex slot PSU and figured out how to turn it on and also increase the output voltage before there was any online guide whatsoever, so I uploaded a vid on how to do it on my channel. This vid will certainly help me to disable the OVP on my unit so I can get over 14.5v and Ill make a new video on that. 👍 Thanks buddy!
Nice video, chapeau for your self- building all these other projects! Do you have info about the HP 1400W 12V, 117 amp ps? It looks like, but... thanks in advance!
