Hello Victor,
You bought 50A CTs, and those are the smallest available from the store. There are smaller solid core on the market but you would need to add a longer cord, 3.5mm jack and optionally a TVS diode. Search this forum and you will see some discussions about various models.
However, from searching the forum here, it doesn’t seem these are a straight drop-in replacement, and will need to be converted. Something about voltage output vs current output:
Are solid cores generally more compact/smaller than the split core ones?
@overeasy did you end up getting the samples from @Automate? I would also be happy to send you a couple as well, if you think this model is a good fit.
The SCT013 is larger than the accuCT 50A. Only the SCT013-000 (50mA output) is compatible with IoTaWatt.
No, I did not.
Hose are a bit smaller, solid core. They are available directly from Echun. I don’t carry them anymore because with shipping to USA and 25% tariff they are too expensive.
They are good, but you need to add a cord and jack.
I have many of them (that I bought with the ECM-1240 I bought over a decade ago). I have been meaning to send a couple to Bob to get numbers for them. I use the following numbers with them:
Model: generic
Turns: 1525 (sometimes 1528)
Phase lead: 1.2 to 3
Clearly, I need to get the samples to Bob, since my numbers are all over the place
They are plain wire, so need a TVS diode (when not connected) and a connector. I have been using these to connect them: Amazon.com: Billmill 3.5mm 4 Pole Stereo TRRS Male to AV 4 Screw Terminal Female Phoenix Block Balun Headphone Earphone Solderless Connector Adapter (4-Pack): Industrial & Scientific
(don’t need to be TRRS, TRS would work fine since only the Tip and Sleeve are used). They are too big to fit next to each other in the IotaWatt, so I use a short extension if they have to be next to each other. I found the quality of the solder on connectors to be really bad and hard to use. I tried cutting extension cords, but I couldn’t find any that used real copper wire that I could solder. This why I ended up buying a lot of the 50A CTs from the store. They work well and are more accurate and don’t require a bunch of time to get the connector and TVS diode on them.
But, if you REALLY, REALLY, REALLY need tiny CTs, the ones I linked do work well.
