Two wire 0.28 inch Digital DC Voltmeter Digital Display Adjustable DC 2.5 – 30V Reverse Protection
Two wires, convenient and simple wiring, easy to connect to the car/battery car/motorcycle, with reverse voltage connection protection function.
Note that the maximum input voltage can not exceed 40V
When the voltage is lower than 3.0V, the display brightness will be dimmed, but it will not affect the correct measurement.
When measuring the voltage below 10V, it will display two digits after the decimal point; when measuring the voltage above 10V, it will display one digit after the decimal point.
Working voltage: DC2.4~40V (with reverse connection protection function)
Detection voltage: DC2.4~30V
Working current: <30mA
Display mode: 0.28″ LED, red, blue, green, yellow (colour optional)
