DC4.5-150V Digital Voltmeter Meter 0.56 " Blue Color LED Power Monitor Panel Meter
The voltmeter compact , range DC 4.5-150V, need external auxiliary power supply. Auxiliary supply voltage range wide, up to 3.3-30V, can work at 5V, 9V, 12V, 24V , etc., without regulation. With three wiring, easy access to car / battery car / motorcycle car lines, with reverse polarity protection, line reversed does not burn . Used to monitor the battery voltage, battery voltage status grasp , can also be used for other products voltage measurement purposes. Note that the maximum input voltage can not exceed 30V, otherwise there is the danger of burning .
