Input 10A 18-32v, output 20A 13.8v (+/- 3%), 22A peak, spikes 100mVss. Lovely compact, 185x75x60mm, 400 gram, and the way I see it, it can easily be waterproofed (no open vents in the housing). Will use at least two myself, one for the Webasto furnace and one for the radio and other under-dash stuff. US$100 including shipping anywhere on the planet. Don't wait too long, there are still a few more left where I bought them, but I also might invent new applications for all the ones I currently have....don't make my HJ-60 turn into one giant converter....:)) -- Bye, Willem-Jan Markerink The desire to understand is sometimes far less intelligent than the inability to understand [note: 'a-one' & 'en-el'!] From: "Willem-Jan Markerink" To: dtlc@helios.net Date sent: Wed, 11 Oct 2000 13:34:32 +0100 Subject: Re: [DTLC] radio Send reply to: dtlc@helios.net On 10 Oct 00 at 20:24, Charles Aarons wrote: > I recommend an Astron 24/12V convertor and using a 12V radio; it's rated for > 20A continuous, 24A intermittent and seems reliable.

The one I offered is made in Germany....;-)) And one more product I will probably buy from the same company in the future is a lovely small 220V->12V/5A charger, 13.8V, high-efficiency (therefor the small size (158x110x40mm, 500gram), just like with 24->12 high-efficiency converters), with automatic switch-off/trickle-mode when charging current drops below 0.5A....manufacturer confirmed that I can run two units in series, to feed a 24V system without shorting....and all that at only US$100 each. This will be my solution for multi-day stays at campings with 220V infrastructure, with 2 permanently mounted chargers....5A is sufficient to run a compressor fridge all the time, and some lights in the evening (currently also checking the latest wave of white-LED products....I have seen some multi-LED units with E27 screw mount, 12V and only 60mA (*milli*Amps....0.7W, 1/10th of ordinary 12V fluorescent tubes!). And all this also to keep the batteries charged during longer periods of non-use in my garage....gotta keep those batteries happy in winter....:)) -- Bye, Willem-Jan Markerink The desire to understand is sometimes far less intelligent than the inability to understand [note: 'a-one' & 'en-el'!]
