Hello all,
I'm new and hoping I can get some good advice for an up and coming project, I hope someone can help me out here ?
I have a 12V 75Ah Leisure battery which is to be the main power pack for a project I am about to start. I know that once this thing is charged up it could produce way over 12V but as it runs down it could only produce 11.9V.
One of my pieces of equipment which is an astrophotography camera needs a regulated DC supply of smack on 12VDC, it defiantly can not go above 13V. I have been looking at DC-DC converters but have found out that they either step up or step down but I have not been able to find one which will take a variable input voltage and still maintain a constant 12VDC output if the input voltage is higher or lower than the output voltage. I need to be able to cover a minimum of 30W @ 12VDC for the output.
Is it possible to make or purchase a module (as small as reasonably possible) which will take a variable input voltage of, lets say ranging from 10-15VDC and output a constant regulated 12VDC @ min 30W (50W would be safer probably) ?????
Can It Be Done ?
Many Thanks for any useful advice
Regards
Paul
