DC 100V 10A Voltmeter Ammeter Blue + Red LED Amp

The factory has adjusted the internal interval of the PCB. If you have a back PCB board, please don’t buy it.

Working voltage:4.5-30V DC Note: The maximum input voltage can not exceed 30V, otherwise there is the danger of burning Working current:≤20mA Display: 0.28" Two color blue and red Measuring range: DC 0-100V 0-10A Minimum resolution (V): 0.1V Refresh rate: ≥100mS / times Measure accuracy: 1% (± 1 digit) Minimum resolution (A): 0.01A Operating temperature: -15 to 70° c Working preure: 80 to 106 kPa size :48×29×21 mm The connection below 10A does not need to connect the shunt: it can be directly connected, respectively, AB short circuit, CD short circuit

DC 3-32V / DC 0-100V：

1. The wiring of this voltmeter is simple. The two wires are used regularly. The red is connected to the positive, the black is connected to the negative, and the reverse connection is protected. 2. Normally, no external working power supply is needed, and the measuring voltage can be directly operated. The measuring voltage range is 3-32V /0-100V. 3, wide voltage operation, the red minimum measurement voltage is 23, the maximum safe preure can reach 40V, more than 40V may be damaged. 4. When measuring voltage below 10V, two digits are displayed after the decimal point; when measuring voltage above 10V, one digit is displayed after the decimal point. Measuring range： Two-wire DC3~32V / Three-wire DC0-100V Power supply range No separate power supply. Measured voltage 50KΩ Working current：
