    These clamps are as far as I can tell the same quality as any other 20A induction clamp you can purchase anywhere. They work pretty well, and seem reliable between the accuracy from clamp to clamp. I am quite satisfied with the clamps for my project.

    I used this to built an automatic dust collector switch in my woodworking shop. I used a double outlet box to house the transformer, a 5 volt mini-brick power supply, an Arduino Nano and two AC outlets. The current transformer goes around the black AC lead to the socket for the power tool. The plug on the other end of the cable is connected to a small bridge rectifier & capacitor to generate a DC voltage. This voltage is connected to the gate of a Mosfet which sends a positive logic signal

    Good product, the measurement range is as specified and the output voltage range is good. The build seems durable and the cable is of high quality. Good for non-invasive current measurement for home appliances and medium power appliances and devices. Fast Shipping, Adequately Packed and at a Low Cost. Not Expected from a Chinese Seller.

    Bought it to evaluate how well it would work in an energy monitoring system that I am designing currently. So far so good. Reasonably accurate.

    Working fine with the arduino. Using OpenEnergyMonitor project to monitor the current.

    This unit replaced an earleir one and works OK. Be careful the core is very fragile and after 3 years I managed to crack my original core.
