I've been using these guys in my london double decker buses to retrofit a radio and PA system in them. the buses use a 24v power system but all the audio equipment here in the states is 12v. i use these in all my buses to retrofit modern audio and PA systems in them. im using a off the shelf JVC deck with a kicker 400w amp, and a PA system i got from london. they handle the power very well and have had no issues with them. i ran them all last summer in the vegas heat (100+ every day) and they never failed me. the amps fried before the converter did.im very satisfied with this product. so much that im going to purchase 10 more units.
thanks for reading

Buy Pyle PSWNV720 24V DC to 12V DC Power Step Down 720 Watt Converter with PMW Technology Now
To preface, I work as an engineering lab technician and put this unit through the wringer to see what it could do.I connect this to a 24V supply (50A capable) and a load bank (300W variable + 288W fixed 12V load).
I found that the unit could 'constantly' convert about 395W (24.5V in, ~12.4V out). Any higher than this and the supply collapses.
I did not test the surge capacity of the claimed 720W. I was under the impression that this unit was a 720W constant supply (which it is NOT). It is a 360W rated supply.
It still will give you a very solid 30A of 12V power from about 15.6 or so amps of 24V power. The standby current is about 35mA with NO 12V load.
All-in-all...this is far better than the PowerStream brand 24V converter that I purchased in the past (and have had multiple failures with). I DO recommend this unit (it's small, stout, easily mountable).I installed this in my 24vdc military M35a2, this little 30amp converter powers my Yaesu FT2900 & other 12v gadgets perfectly, no issues so far.
May 2013 I have added another 12v radio (Uniden Bearcat 980)and dual 12v outlets to the mix and all work fine with this unit, very stable 12.5v output when both radios are on and using the outlets.

The Pyle converter is a lousy product lacking competent customer support or even a technical manual that ended up being a waste of money, time and effort.After spending a lot of time trying to get the converter to work, I posted this cry for help on the Amazon forum: "Instead of 24v going in, I have 30v going in and nothing coming out the 12v leads. The fuse is fine. Is the input voltage too high?"
Indeed, two of the four people who responded thought that high input voltage might be the issue. But then Christopher B. wrote that his converter was "running on about 32volts input, (out put 12.5 volts with no load), but the input filter caps are rated at 35 volts."
I'm not sure where Chris got that information, because I can't find a manual for Pyle converters. None was inclosed with the packing slip when it arrived from Amazon, and at the Pyle Audio website for the 720 converter, clicking the "Manuals and Downloads" button gets you the notice that "No Manual And Download Available".
And technical support at Pyle Audio might as well not be available either. Both times that I wasted enough time on hold to get through, the irritated techs seemed bewildered by the problem and, with the surliest of New Yorker attitudes, blew me off without any useful advice.
Oh, the fourth person who responded to my call for help? Mike A. wrote, "i had no luck either, i dont know if they work or what and i just gave up and someday plan to buy a 24v radio and forget about the converter."
Guess I'll pretty much do the same after posting this review to warn the world to never get near a Pyle product.
