I have a working knowledge of electronics and circuits but am a little lacking when it comes to design. I can follow the diagrams but designing was never my game.
I am wanting to supply a clean and (relatively ) consistant 12v DC @10amps (or better) to my DC TV and some other DC appliances in my motorhome. There is a TV, Security DVR, Modem Router and a NAS unit. It of course feeds from a battery bank and charges from solar. There is more than enough voltage and current from the 1300ah bank. My concerns are the fluctuations in the voltage from the solar. It can be as high as 14.4v.
Currently the items run from 2 x 12v variable power adapters for a car. These are 5 amps but can only run one thing at a time.
I worked once with a unit that provided a stable 12v 20amp with input up to 16v. I cant remember where I got it from or even the name.
I would very much appreciate if anyone had or would consider drawing a diagram for something like this. I would prefer something with a reasonable current rating, 10amp min. I would also like to be able to pull 9v out of it as well but can handle living without this.
All thoughts would be very much appreciated.
Please and Thank you Mal
