A project log for Isolated +-50 A current sensor

Very simple +-50 A isolated current sensor with 1.5 MHz bandwidth based on Anisotropic Magneto Resistive sensor technology (MCA1101-50-3).

Three PCBs were milled and assembled

Housing has been designed with special care to provide 4 kV RMS isolation barrier.

Im always pouring some concrete to bottom part of housings because it has much nice feel when using it.

And finalized unit below (ok I admit it is missing some labels :)
