LCD Backlit DC Voltmeter (doesn't require power)

Right on, ctpres. That's what I use in my meter panel.

Double post.

Rich - Let me know when you find one of the HALL EFFECT +/- 75AMP DC Current meter plus the transformer for around $30.

I have one of these now and need two more for upcoming mods.

I DO NOT want to go with the SHUNT TYPE current taps as then I have to deal with high current 'HOT' DC wiring running back to my meter console.



I sent email off to the ROSESANNA Company inquiring about this photo they have on the web site but they never answered back...


The FCB ELECTRONICS company is wanting over $800 for their lising shown above. I purchased the same thing back in 2008 from SURE ELECTRONICS ebay/China for $35 I think it was. Sure wish I got two or three of them...

HONEYWELL doesn't carry the CSCA-A sensor transformer line anymore is what I have been told. They used to sell for around $50 with-out the wiring harness...

No power statement is just way to describe new style meter. Older version was four wire and required different power source. New version just needs two wires and gets meter power from voltage being measured which makes for a much simpler installation. Only down side is the range of voltage it will measure is limited on the low end (stops working around 7.5 volts) but that is not problem for typical 12 RV use. If your battery gets below 8 volts it really won't matter. Enjoy.
