E-mail Print

DISCLAIMER: This design is experimental, so if you decide to build one yourself then you are on your own, I can't be held responsible for any problems/issues/damage/injury that may occur if you decide to follow this build and make one yourself.


Per the latest video below I should have a few kits available for other folks to retro fit there CSI 3000 series power supplies. Check back here soon for more info as I'll have full instructions and hi-res photos available. Interested in getting one of these kits?......then get in touch via the contact form on my main menu above. If I can gauge enough interest then I'll build up a batch.


Quick 10min video on the modification of my CSI3003X5 Bench Power Supply. The addition of off-load current setting.

Update 12/01/14 - Production Pcb!


Update 10/12/13 - Replacing the pushbutton with a 555.

No more than you can pickup in the video. I am selling these so would rather not give away my secrets - 555, op-amp and a relay......:).

It was there indeed. I looked at your video agian hoping to find a filename in the top bar, but it wasn't there. I found it looking for a string in your screen: "to keyboard2 cn2-5", and that sent me to http://www.circuitspecialists.com/pdf/3005X_schematic.pdf
Thanks :)
