Двунаправленный трансформатор тока diymore 50/100/200/40A

The delivery times predicted by Ali Express were not exceeded. The parcel has been on the way to the Republic of Belarus for 22 days. It could have arrived earlier, but the New Year holidays delayed not only it, but also 2 more of my parcels. As a result, they arrived at the same time, although they were ordered at different times. The seller cooperated in tracking the movement of the parcel. He also helped with finding the operating instructions for the device. The service he provided: *****. About the device. The meters arrived intact. This is a nitpick: (there are small abrasions on the screen in different places (does not affect the perception of information), an attempt to repeat them was unsuccessful, probably this is not delivery, maybe it appeared during production .... on the individual packaging of each device there are minor creases and damage. The operability of the devices was checked, all 5 pieces are in good working order, there are no complaints about their operation. The expected operating range for me is: 12 volts current up to 3.5 amperes. I do not have the opportunity to test in a wider range. The accuracy in the above range corresponds to the description. The body of the device is cast in one piece. It does not have adhesive glass + = tightness as part of a sealed device. The wires and convectors look reliable. According to the seller, the cable connecting the connecting sensor and indicator can be increased by you up to 50 cm (you can discuss the issue of the complete set with the seller). There is an inaccurate interpretation in the instructions for the meters. When you hold the button for 6 seconds, there is no reset to factory settings, and setting the reference point relative to the current flowing through the meter at the moment of pressing .... -3. -2. -1. 0. 1. 2. 3 .... This function will allow you to track current deviations from the nominal both in + and -. This is a very useful function that I will use. :) If you use 2 devices at the same time, then this is generally a must have. This setting is not reset after turning off the power. The purpose of the function with pressing the button for 3 seconds is not clear to me, what is it and why ??? The sensor has interference suppressing capacitors +. In general, the impressions of the devices are wonderful, ***** are they reliable? Time will tell. There is only one serious regret: I really regret that I did not find this device earlier ... I could have saved a lot of money by buying 5 more of these devices from this seller and not from Derbauer.  Читать ещё

Точно такой же как на фото. Работает. показывает ток и напряжение. Измеряемый плюсовой провод пропускаем через кольцо, на экранчик подключаем минус на черный провод и плюс на красный. Жёлтый провод цепляем на тот плюс, который хотим измерять, тогда ещё и напряжение будет показывать.  Читать ещё

аккуратно, проверил- работает,при токе 0.5 а показывает 0.5А, ПРИ ТОКЕ 98 А - ПОКАЗЫВАЕТ 98а  Читать ещё
