This what i use and it has worked great for over five years.
I did make a couple modifications to it but it will work great without them. Remember that a power supply like this first converts the ac input into dc. So using a dc input is no different than an ac input for this type of device.
I replaced the dc rectifier with current limiters, put in higher voltage capacitors. and secured some of the parts better with rtv. See the following link for the details.

I certainly hope it's the DC-DC converter as it's under warranty. I have the mess cleaned up and I drove the vehicle a short distance yesterday without a DC-DC converter. That's a prescription for disaster in the long term but not a big deal in the neighborhood.
I'm going to mail the converter back to the manufacturer tomorrow. They have offered to test it.
DC-DC converters have proved to be the most difficult part of the conversion process for me. I may ultimately switch to an alternator as they are more efficient than DC-DC converters.
So you like astronomy Dave? So do I.

Your DC-DC looks exactly like mine which went bad, but I think I may have had a different problem. When I look at the photos (attached) it looks like it's the AC wires that fried.

I also had a DC-DC converter go south - for no clear reason. However, after
adding in fuses and replacing it with a new unit, no problems. It could
very well have ingested something that caused a short inside the converter
(that's my latest thoughts on my near disaster) - or it's just a piece of
junk not used to being in a hostile environment (e.g. vibration, heat). In
any case, I made sure that all of the connections were solid, and any place
that had a chance of letting the magic smoke out got a fuse.
Cheers, Peter

Thanks Paul.
A DLS-55 will work with a purely DC car?

After my original DC-DC failed, I replaced it with an Iota DLS-55 and it worked just fine. I'm upgrading my traction pack to 216V so I am now installing this one,

I've been using the one from EV Source. I can't fault their customer service.
I mailed it back to them for testing yesterday and I'm certainly hoping they find a flaw.
I drove my 914ev 6 miles yesterday (without a DC-DC converter). Everything seems fine. I think I had what Peter Thompson (of this group) called "a near disaster". That phrase has been in my mind lately.
