از اين ماژول مي توان جهت سنجش ولتاژهاي DC در محدوده ي 0 تا 100 ولت و همچنين ساخت منبع تغذيه هاي متغير با ايسي هايي از قبيل LM2596 و ... استفاده کرد. ويژگي ها: ولتاژ تغذيه ماژول: 4.5 تا 30 ولت DC محدوده ي سنجش ولتاژ: 0 تا 100 ولت DC حفاظت در برابر بر عکس زدن قطب هاي مثبت و منفي رزوليشن: 0.1 ولت کاربردها: منابع تغذيه پروژه هاي الکترونيکي صنايع

The voltmeter basic performance parameters are as follows: Opening size: 45.5mm * 26.5mm Dimensions: 48mm * 29mm * 21mm Range: DC0-100V Display: three 0.56 LED digital tube Display color: green-red Refresh rate: about 500ms / times Accuracy: 0.5% (+/- 2 words) Supply voltage: DC4.5-30V (independent power supply) with reverse polarity protection Wiring instructions: Red line: positive power supply, we need access to power within the positive range DC 4.5-30V Black: negative public, both the negative power supply is measured with reference to the negative Yellow line: positive measuring signal input Description: Header requires a separate power supply, power supply range DC 4.5-30V, when access to the power supply line between the red and black, Header will show 0.0, then you can access the yellow line and the black line between the measured voltage and the measured voltage range DC 0-200V
