soundtrane Posted June 16, 2013 Report Share Posted June 16, 2013 This is a PSC CartPower unit - bought in 2007, running strong but discontinued by PSC a couple of years ago. It has six outputs, but nowadays i need more. Hence the mod - I added 4 more outputs using Switchcraft locking DC jacks each isolated, filtered and poly-fused as the original outputs. This will ensure i have enough outputs to power the new units on my cart - A MixPreD, Schoeps MiniDA-42 power supply for the SuperCMIT, iPhone charger, and one extra standby output. I used heavy gauge 14 AWG wire, and some heavy soldering to take care of at least 5 Amps of current. I took out the SMPS since i never use AC to power anything, so it was redundant inside the CartPower. It could be put to use elsewhere, I guess... I had purchased an extra circuit board as a standby a couple of years ago. Ron Meyer was very kind to send me an empty CartPower chassis recently. I now have a standby unit if ever my first unit fails. I'll wait until the new Cantar X3 arrives, and then will redesign my cart. That will probably be the time to look at the new DC distribution units that have emerged, with LiFe batteries... Quote Link to comment Share on other sites More sharing options...
Constantin Posted June 16, 2013 Report Share Posted June 16, 2013 Looks very interesting. Just out of curiosity, why didn't you just attach a HotBox or something similar (or self-made) to one of the outputs? Quote Link to comment Share on other sites More sharing options...
soundtrane Posted June 16, 2013 Author Report Share Posted June 16, 2013 Hi Constantin, I wanted to have completely isolated outputs, which wont be possible if i throw another distribution box into one of the existing outputs. also the capacity of the output being distributed will be a limiting factor. Each one of these new outputs are poly-fused to break contact at 3A and have an LC filter on them. -vin Quote Link to comment Share on other sites More sharing options...

soundtrane Posted June 16, 2013 Author Report Share Posted June 16, 2013 Tom, thanks my friend, but nowhere close to what you would have done. Next thing i am trying to learn is to design PCBs. downloaded a piece of software today (Eagle), will try it out... Quote Link to comment Share on other sites More sharing options...
Shastapete Posted June 16, 2013 Report Share Posted June 16, 2013 Vin, What does your filter circuit look like? I see some caps and resistors, how is it wired up? Quote Link to comment Share on other sites More sharing options...
soundtrane Posted June 16, 2013 Author Report Share Posted June 16, 2013 not a resistor, that is an inductor... simple LC filter - inductor on the + line and cap across + and - Quote Link to comment Share on other sites More sharing options...
