Основные характеристики

  • постоянное напряжение до 60 В
  • постоянный ток продолжительно 50 А, кратковременно до 150 А
  • текущая/максимальная мощность кратковременно до 3000 Вт

В верхней строке экрана отображается текущие ток и напряжение. Нижняя строка справа — текущая мощность. В нижней строке слева циклически отображаются:

  • минимальное напряжение в цепи за время измерений
  • максимальная мощность за время измерений
  • максимальный ток за время измерений
  • ёмкость в мА/ч за время измерений
  • потребленная мощность в Вт/ч за время измерений

Источник тока подключается со стороны SOURCE, нагрузка со стороны LOAD.

Дисплей на фото может показаться узко-обзорным, но в действительности показания прекрасно видно с любого угла.

Провода в силиконовой негорючей изоляции.

Ваттметр может питаться от измеряемой линии, если напряжение в ней более 4,7 В. Энергонезависимой памяти у него нет и при отключении измеряемой цепи он не сохраняет измеренные значения и все показания сбрасываются. Чтобы они сохранялись, должно быть подключено внешнее питание с напряжением от 4,7 до 60 В. В корпусе есть отверстие внутри которого расположен трёх-штырьковый разъём:

Нижний контакт с пометкой G — минус, средний контакт плюсовой. Для удобства использования я установил свой разъём.

Так выглядит примитивный «измерительный стенд» для замера ёмкости аккумуляторов. Хорош он в первую очередь тем, что не имея дорогостоящего специального зарядно — разрядного устройства, можно замерять ёмкость аккумуляторов при разряде током до 50 А. Причем точность будет до 1 мА/ч. Подключая на выход нагрузку разной мощности регулируется разрядный ток. В конце разряда главное не пропустить момент при котором аккумулятор нужно отключить во избежание глубокого разряа. При этом контролировать оставшееся напряжение правильнее непосредственно на контактах аккумулятора другим вольтметром, т.к из-за падения напряжения на подводящих проводах показания на приборе будут занижены. Либо подключать максимально короткими толстыми проводами.

    Just about all of whatever you state is astonishingly appropriate and it makes me ponder why I had not looked at this with this light previously. This particular article truly did turn the light on for me as far as this particular issue goes. Nevertheless at this time there is 1 point I am not really too comfy with and whilst I make an effort to reconcile that with the actual central theme of the issue, let me observe exactly what all the rest of your readers have to point out.Very well done.

    Hey! This is kind of off topic but I need some guidance from an established blog. Is it difficult to set up your own blog? I’m not very techincal but I can figure things out pretty fast. I’m thinking about setting up my own but I’m not sure where to begin. Do you have any points or suggestions? Cheers

    Today, I went to the beach front with my children. I found a sea shell and gave it to my 4 year old daughter and said «You can hear the ocean if you put this to your ear.» She put the shell to her ear and screamed. There was a hermit crab inside and it pinched her ear. She never wants to go back! LoL I know this is totally off topic but I had to tell someone!
