[RE-wrenches] DC-DC converter question

[Kevin Pegg]

We have just received some product from solar converters. I don't believe they are out of business. 

We use their 48-12V converters frequently for situations like this. Lower idle loads and higher efficiency than using a 12V power supply from Iota or others. 

Though have had a couple failures of these converters in recent years.

FYI.....It appears that Solar Converters may be out of business.
