Description:

DC 4.5v-30V 0-50A Dual LED Digital Voltmeter Ammeter Voltage AMP Power Meter
The small size of the two-color dual instrument. Voltage and current can be displayed on the same screen at the same time
This instrument test voltage, current, power supply is taken from the test loop. No additional power supply
The the instrument test voltage supply range: DC4.5 ~ 30V
Note: The maximum input voltage can not exceed 30V, otherwise there is the danger of burned
The instrument is equipped with three wiring. Convenient access to car / battery car / motorcycle car line. Used to monitor the battery voltage, Grasp the battery voltage state, can also be used for other products, the use of Voltage/current measurement.
