Description
Red 0-200V Measurement Range 4.5-30V Power Supply Volt Meter Mini Digital DC Voltmeter Display Three Wire Voltmeter
Product Description
1. The meter head needs independent power supply. The power supply range is DC 4.5-30V. When the power supply is connected between the red and black wires, the meter head will display 0.0. At this time, the measured voltage can be connected between the yellow wire and the black wire to be measured. The voltage range is DC 0-200V 2, The use of three-wire voltmeter electric vehicles is more complicated

Installation Instructions
Wiring instructions:
Red line: the positive pole of the power supply, which needs to be connected to the positive pole of the power supply within the range of DC 4.5-30V Black wire: Common negative pole, which is both the negative pole of the power supply and the reference negative pole of the measurement Yellow wire: measuring signal input positive
