PCB Build
(Still waiting for J4 screw terminals to arrive - this is what connects back to the CMRI node)
Quick and dirty, but using the same current transformer that the NCE version uses (1:200 turn ratio)
- LED1 electrically does not have a polarity as it voltage is AC and swings positive and negative
Wiring
TODO: Add example of installed detector.
Timeline
Boards shipped from pcbway today
PCBs arrived and bench testing is complete
1st 5 units are built and tested
Starting second group of 5
Demonstration
This video demonstrates over-current and reset using a 2A high current short in parallel with a 200mA load across the track. Over-current LED comes on and resets with 200mA load on the track after the short is removed.
