Range DC DC0-100V, 2 and 3-wire products Universal, to break the routine voltmeter, is the latest design, can work directly in 5V, 9V, 12V, 24V and other circuits, without regulation. With three wiring, easy access to car /battery car / motorcycle-car line, with reverse polarity protection, line reversal will not burn. For monitoring thebattery voltage, battery voltage state to grasp, it can also be used for other products voltage measurementpurposes.
Note： 2 line with the highest input voltage can not exceed 30V, otherwise there is the risk of burnt.
NOTE: Three-line voltage range 0-100V, but also can be used as second-line use in 40V voltage to within
