[Steve001]

Afternoon,

Just been having a sort out and found this board I made a while ago , unfortunately I have never got round to use it

please find attached some files I still have the pcb cam files if anybody wants them send me a pm and I will email them to you as they where too large to upload.

Board made with Eagle 6.0.1

maybe jordys current sensor component might work it I am not sure haven't looked .

Vout = Vcc/2 +(1.25*300/200) volts

Power supply 5 Volts Dc

data sheet found here

Hope someone finds it useful,

Hopefully will try and have a go with it in the new year sometime ..

Evening All,

Done some testing today with board,

Attached excel results

Tested with a 100ADM SCITS Current Injection System and a fluke 175 True RMS Meter

Had trouble getting test pic circuit to work correctly, will try again when i have more time and do a DC test also

Hi Steve,

Just a question, why are you passing two times the cable through the sensor ? I'm using a clip sensor and need only one pass.

Hi Bernard,

I am not there is only one loop through the sensor but two cables as the test leeds are only 6mm2 Cable, so by using 2 cables i can get 100 Amps
