معرفی از این ماژول می توان جهت سنجش ولتاژ های DC در محدوده ی 4.5 تا 30 ولت بدون نیاز به منبع تغذیه مجزا استفاده کرد. کاربرد ها منابع تغذیه پروژه های الکترونیکی صنایع مشخصات ولتاژ تغذیه ماژول : 4.5 تا 30 ولت DC محدوده ی سنجش ولتاژ : 4.5 تا 30 ولت DC حفاظت در برابر بر عکس زدن قطب های مثبت و منفی سه دیجیت 0.56 اینچ Introduction The voltmeter wiring is simple, only need to pick two lines, the table reversal protection, reverse does not burn. In order to achieve optimum measurement accuracy, the voltmeter will be different according to the measured voltage automatically move the decimal point position. Measure the voltage below 10V, displayed after the decimal point two; 10V voltage measurements displayed after the decimal point one. That is able to take care of the battery user needs, but also cater to the needs of the higher voltage measurement on the measurement accuracy. The voltmeter can be used for motorcycles, cars and other monitoring battery voltage, timely grasp battery status. Other voltages can also be used formeasurement purposes. Specification Range: DC4.5-30V (No need aditional power) Display color: Red Refresh rate: about 500mS / ...
