Current sensor port on MP2

Hello,

I'm new in victron product and i've seen so far in all videos a jack port for the current sensing.

I got only terminals, is that normal ? Does it mean I have to cut the jack connector of my sensor ?

@Terriblement

The older 3.5mm jack connector has recently been replaced with the new connector block you see on your device.

The pins on the terminal from top to bottom are: INT (top), EXT (middle), COM (bottom).

You can still use the old current sensor but you will need to cut off the jack plug and then wire it up like this:

  • Remove the jumper wire between the INT and COM terminals
  • Connect the red sensor wire to the EXT terminal
  • Connect the white sensor cable to the COM terminal

It is highly recommended that this be done by a qualified technician. The other option is to wait for the new current sensors to be available without this jack connector.

This is a TRS standard jack. I'm going to hack my YHDC 100A 50mA (SCT013) current sensor to make it fit as the instructions above. I will do this by using a female to female adaptor. One end is current sensor goes to adaptor then other end is old high quality leads which I don't mind cutting into a 1m length that I can crimp and put into the multiplus as per this thread.


Questions. Based on TRS headphone jack diagram I have supplied I use the sleeve wire into the multiplus COM port and I use the tip wire to the INT port?


Update: Found some info here: https://www.electroschematics.com/split-core-ct-primer/
