ماژول ولتمتر سایز 0.36 اینچ 3 سیمه روپنلی قرمز DC4.5-30V از این ماژول می توان جهت سنجش ولتاژهای DC در محدوده ی 0 تا 30 ولت با ولتاژ تغذیه 4.5 ولت تا 30 ولت می باشد. کاربردها منابع تغذیه پروژه های الکترونیکی صنایع مشخصات ولتاژ تغذیه ماژول: 4.5 تا 30 ولت DC محدوده ی سنجش ولتاژ: 0 تا 30 ولت DC رزولیشن: 0.01 ولت سه دیجیت 0.36 اینچ Introduction The voltmeter wiring is simple, only need to pick two lines, the table reversal protection, the reverse does not burn. The voltmeter start voltage is low, the red just 3.2V, just 2.7V Green, the blue just 3.0V will be able to measure correctly, start with the price of two-wire voltmeter voltage is the lowest anywhere in the world. This will greatly facilitate the use of the lithium battery, 18650 battery users. When the voltage is lower than 3.5V, the display brightness diminishes but does not affect the correct measurement. 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. ...
