United States VT from amazon (or other similar marketplace)?

Hi All,

I ordered my IoTaWatt today, the main unit from the circuitIQ link…but it appears to come with nothing. I was able to buy the CTs from stuff.iowatt, but there are no VTs up for sale that I can find, and all of the external links seem to be for UK or AUS 230/240v plugs. I tried to take the model numbers visible from the docs site in the vt drop down and plug them into amazon but didn’t fare particularly well. From the hw docs, it looks like i need a 9vac transformer with a 2.0mm barrel plug, but even that…isnt turning up great things on amazon for me, i can only find 2.1 or 2.5mm.

Anyone know of a good place to buy United States Nema5-15 9 vac transformer?



That should work and reasonably priced.

That is a 5.5mm OD x 2.1mm ID unit, which I believe is correct, but Bob will know for sure.

I recommend this unit from Jameco. It’s included in the configuration tables.

I have not calibrated to the Ideal 77DA-12-09 carried by Github. I am actively buying parts from them right now so I will get one next order, calibrate and add to the tables.

Problem with sourcing components all over is the minimum shipping on each. I believe CircuitIQ is gearing up to offer the whole shebang.
