Description

Led Vu-Meter

Индикатор выходного уровня на базе микросхемы LM3914.

На плате имеется стабилизатор напряжения на 7812 который расширяет питающее напряжение индикатора до +30В.

Индикатор подачи напряжения на плату.При необходимости можно не запаивать.

Регулировка чувствительности входного напряжения.

Так же внешними резисторами можно задать ток протекающий через светодиоды, выбрать режим работы линейка либо точка. Видео работы
