    I just recently mounted this meter in a metal box and wired it up to check power consumption on my window air conditioner. It works perfectly!

    На сайте banggood.com был куплен данный приборчик. Доставка? Приехало и ладно, некспеху. Вещичка знатная, простая, пока работает без нареканий. Засунул в корпус. Что получилось смотрите на Ю-тубе. https://www.youtube.com/watch?v=1fGnn_gQcZE&feature=youtu.be

    I bought this power meter to be able to measure the power usage of any 230v device that I own in order to understand how much power the device pulls and it really delivers with that information. It is easy enough to connect a power plug on one side and an outlet on the other in order to put it in between any device. For added convenience I am also designing an enclosure for this to be 3D printed.
