The voltmeter's internal regulator can only handle 30-35V. You need to power it separately to measure higher than that. If the voltmeter has only 2 wires, you need to modify it so that there is separate +'ve power for the meter vs the measurement line.
Great job! But it would be even better if the author showed a diagram of this product in the clip. . Отличная работа! Но было бы ещё лучше, если бы автор показал в клипе схему этого изделия.
Good job! It seems this circuit over drives the diodes and must be modified. Red / green / yellow led voltage drop must be less than 2 volts unless be drived with currents more than 20mA results in red led turned on with almost yellow and shortened its life. Thanks!
Hola, me gustan mucho tus vídeos, los encuentro muy practico y sencillos. Sabes que siempre he tenido problema para verificar la carga de la batería, pues los medidores solo miden voltaje pero no amperaje y menos aún la potencia de una batería. Podrías diseñar una herramienta, para ese efecto. Es decir, medir la potencia de una batería. Gracias
🤔Объясни зачем в схеме диодный мост? Зачем так усложнять, если можно просто через резистор подать с +12 вольт питания прибора и в итоге все тоже самое, только без бреда с диодным мостом.
sanırım o köprü diyodu kullanıcı hatasının onune gecmek icin eklemişler. i think he added this bridge so that amateurs might connect 12V terminals wrongly. in this way (with bridge) if they can connect wrong, the circuit works still or you use a transformer to inputs of diode bridge instead of dc ps
Veery interesting, useful. 1 question. Can we use another power supply different to 12. Volts. Perhaps 24 , 50, 75 or even. 120 vdc.? Plz. Am waiting ur answer. Thanks you a lot.
You need to power the meter at under 30-35V, as that is the maximum for the internal voltage regulator. To go higher that about 30V, you must use a 3-wire meter where the power +ve and the measure +ve are separate.
Уважаемый мастер,я попробывал сдиодным мостом BR810,но на светодиодах напряжение показывает на красном 1,5 вольта,на зелёном 2,3 вольта,короче занижает вольты. Стабилитроны вообще 0,5 вольта.Где я накосячил? У вас в видео сопротивление стоит на 200 ОМ.
yaşamak da zor, ölmek ise cok kolay. sen neden tez yoldan kendini öldürmüyorsun? Burada amaç, kendin yapıp bir seyler öğrenmek ve amatörlük ruhunun zevkinden tatmak. o kadar paran varsa t7 almak yerine ver parasını bu işleri yapacak bir usta tut, daha kolay olmaz mı?
