Re: [Electric Boats] Re: 48v diesel telecommunications standby gen?

 

A little bit more info from these guys. The PMA looks like the same unit

another fellow didn't like your automotive alternator idea and i suspect that he might be right.....   take a look at this as an idea for a not TOO expensive alternative

down the page a bit.. the "dual renegade PMA"
http://www.mwands.com/index.php?main_page=product_info&cPath=7&products_id=502

there are clips on the site showing how it is built and what it can do....  seems to be configurable to 48v and CAN provide very high amps

Good thread. I am considering using a new 10 hp air cooled diesel on ebay for $619 and (4) automotive alternators to charge a 48 volt bank. Entire set up should be only $1K and produce just shy of 7kw of charging.

I'm thinking of using a 3phase generator . Use three transformers to bring the voltage down to the required value . Make the output DC via a 3phase rectifier. Should make a simple charger.Chris S--- In electricboats@yahoogroups.com, Michael Mccomb <mccomb.michael@...> wrote:>> other than the Panda stuff which is VERY expensive has anyone come across a 48v dc diesel charging system....  i'd rather use a sort of RAID approach with a much less expensive diesel/PMA system but am pushing the limits of my understanding to devise such a system....  seemingly both diesel engines AND permanent magnet alternators of sufficient power/capacity can each be had for under $1k... some electronics is undoubtedly needed but adding this would still bring a system in perhaps 10k under the Panda price> > one can stumble across all sorts of reference to 48v diesel units used for telecommunications systems but i have had great trouble actually tracking such a unit down>------------------------------------Yahoo!
