0V to 100V mini digital voltmeter | How to use? | For DIY projects

Описание: the measuring range of the voltmeter is wide, it is DC0-100V. additional Power supply is needed to turn on and the working voltage is DC4.5-30V (Red and black) . there is no protection when the cables are not connected correctly so be careful The resolution of the voltmeter screen is 0.1 V .This voltmeter is suitable for who want to make DC power supply, because this can save costs. and that can be used when the voltage must be measured from 0 V.  DC 0-100v 3-bit Digital Red LED Display Panel Voltage Meter Voltmeter
