N60/N30/N20/N10/M30 CT selection and Load MAX current formula
#1
   
every CT clamp input channel will have two resistance. for example, CT2 channel are R23, R24
   
use the formula let input voltage <700mV

if your CT clamp sensor is 2000:1
Load current=30A,
input voltage = 5.1R*2*30A/2000=153mA (VIPN)

so if input voltage <700mA , use 5.1R resistance on PCB, 2000:1 MAX can detect 137A AC220V load.

if you want support more large current, you can change the  resistance or change CT 2000:1 with other models. Just use by the  formula.

Hi,

I think you have an error on your product page for the DL-CT03CL2.0 current transformer.
https://shop.kincony.com/products/25a-cu...s=e&_v=1.0

You list it as rated 0-25A, but the DL-CT03CL2.0 product information says it is rated for 0-5A? This is confusing, I would like a CT that can measure 10-20A 230V subcircuits with the N20.

Thanks

"DL-CT03CL2.0 product information says it is rated for 0-5A? " where ? take a photo.
