Dual LED Digital DC 100V 10A Voltmeter Ammeter Voltage Amps Power Meter
2 in 1 function Voltmeter Ammeter
Dual color LED Display (Blue and Red)
Voltages and Amps are shown at the same time in the display
The power supply can be taken from the test circuit, no additional power supply as long as the supply voltage doesn't exceed 30V.
Power supply DC 4.5~30V range (Attention: The supply voltage cannot exceed 30V, or the unit will be destroyed)
This meter has three wires for easy connections to a car /battery car/ motorcycle car which can monitor the battery voltage status.
