On my mobile sound cart I have several wireless RF receivers that run on 12v. I'd like to build a small distribution box from my main 12v powersupply. Mainly to prevent shorts from loose plugs, as I am currently using Y cables and W cables to multiply my power... loose coax jacks tend to short out on any grounded metal.
Two questions. I'd like to use a polyfuse on each output so if it does short, it will interrupt flow.
And, I'd like to consider filtering any potential noise on the power that could be shared between the receivers.
Its gonna be a 12 port box, with one power input. The line that feeds its can handle 3A at 12v. Each RF receiver has about 200ma demand at 12v.
Currently I was planning on running a rectifier on the input and then feeding that directly to each output, with a polyfuse just before each output. And LED for status of the polyfuse would be nice if easy to incorporate. Ideally only on when the fuse is blown...
The addition of capacitors to filter out possible RF bleed into the powerline is the second question. Typical RF range would be 500-900mhz. I'd assume that the receivers are designed to filter the power themselves... but I had some recommendations to consider this in the design. Any thoughts?
Thank you for any help.
