I was wondering the same thing as SteveH above with using only one converter for both meters, but I wired mine exactly as GJR did here.

I'm about 95% sure that would be a bad idea. Since the ammeter is on one side of the power and the voltmeter is on both sides, I suspect the feed-thru to the common ground of the meter power would likely be a big problem.

GRJ, I ordered more of both the meters and the DC-DC converters for future use. (Once again, everything arrived in about a week, nice!) I looked around a little at DK & Mouser for some possibly lighter duty and less expensive DC converters for stock, but these were hard to beat from what I found.

Yep, other than being a bit larger than other isolated converters, these are a pretty good deal.

Here's a good source for isolated 5V-5V and 12V-12V models: B0505S B1205S B1212S B2405S 1W 2W Isolating Switching Power Module.
