Hello, Some years ago I bought this KIT of AC sensor to turn relay on when current flows. link https://www.aliexpress.com/item/32811343304.html?pdp_npi=3%40dis%21USD%21US%20%2421.72%21US%20%2421.50%21%21%21%21%21%402101c67a16952958184065456e1642%2164497010017%21im%21%21 Finally have put this together but the problem is the relay is buzzing (50hz or something) when it should just stay on. What can be the problem? I tried adjusting the trim pots but they do not adjust this. They one adjusts on/off thershold the other who knows what. |

Problem solved. You have to adjust the theshold pot without any load connected ! Still waiting for reply from manufacturer about second pot. |
