Voltmetar 4,5 – 30V Volt Metar mini-ekran

Opis

Potrošnja manje od 20mA i radni napon od minimalnih 4.5V, pri čemu je predviđeno odstupanje ± 1%, ovaj modul čini jako poželjnim u svuim projektima pa čak i u IoT kategoriji. Minimalnimalne dimenzije i povezivanje putem samo dva komunikacijska kabla, koja se kopčaju na sam izvor struje, čine ovaj modul skoro pa idealnim za mjerenje DC napona.

Napon preko 30V može oštetiti uređaj!
