จอแสดงผล ค่าโวลต์ DC voltage meter head 0.28 inch LED DC 0V - 100V (สีเหลือง)

 

This voltmeter is small in size , DC DC 0 - 100V , 2- wire and 3- wire products are common, breaking the conventional voltmeter, is the latest design, can work directly in 5V , 9V , 12V , 24V and other circuits , no need for voltage regulation. Equipped with three wirings , it is easy to connect to the car / battery car / motorcycle car line, with reverse connection protection function, the wire connection will not burn. It is used to monitor the battery voltage, keep abreast of the battery voltage status, and can also be used for voltage measurement of other products. Note that the maximum input voltage of the 2- wire cannot exceed 30V, otherwise there is a danger of burning . 

Note: The three-wire use voltage range is 0-100V, which can also be used as a second-line but the voltage should be within 40V.

 

2- wire working voltage: 4.0 ~ 40 V ( with reverse connection protection )

2- wire detection voltage: 0.0 ~ 4 0V
