Let me explain.
I am in Canada. The shipping from the US is either “cheap” and very slow, or expensive and slow or stupidly expensive and fast. Also the conversion rate makes what seems to be an inexpensive item start to get beyond my budget. As an example, the Iotawatt I ordered is taking a minimum of 5 weeks to get here and has cost me at least $231CAD (I will still have to pay brokerage fees when it arrives). I buy 10 $15USD CTs and they would end up costing me $300CAD by the time I am done, and wait 5 weeks. That makes this little hobby project way to expensive.
Digikey and Mouser have arrangements with shipping companies to keep costs way down, eliminate brokerage fees and are 2 day delivery. So, unless I am really forced to go somewhere else, I prefer these suppliers. eBay and US boutique suppliers are just too expensive/slow.
To keep costs down, I am happy to attached my own cables and diodes.
I also have a very cramped panel. I doubt I could fit 10-14 split cores. Small solid core CTs would work much better.
So rather than have you guys sift through digikey and mouser for me, I thought I would suggest one an see if anyone has tried them.
Other manufacturers of economy CTs from digikey/mouser would be: vacuumschmelze, Pulse, Talema, Kemet, CR Magnetics. Has anyone tried the economy version of these with any reasonable success?
