AmmetersDC 100V 10A PanelSpecifications:Working voltage of Meter itself:DC 4 - 30V(The maximum input voltage can not exceed 30V. Otherwise the meter will be burned)Working current of Meter itself:20mAVoltage Measuring range: DC 0 - 100VCurrent Measuring range: DC 0 - 10AVoltage resolution (V): 0.1VCurrent resolution (A): 0.01AMeasure accuracy: 1% ( 1 digit)Display: 0.56" digital tube, Two color blue and redRefresh rate: about 300mS / timesDimensions:48mm*29mm*26mmOperation Temp: -10-+65Line:black - red : Working voltage of Meter itself:DC 4 - 30Vblack - yellow : Voltage Measuring range: DC 0 - 100VPackage Include:1x DC 100V 10A Voltmeter & AmmeterDC 45V30Vand This Green Red Blue DC Voltage Meter with DC4.5-30V range. It is easy to read, install and useAnd it is self-powered version and supports Reverse polarity protection.When the voltage is under 10V, there will 2 readings after decimal point, which mean the accuracy is 0.01 when it is under 10V; when it is above 10v, the accuracy is 0.1No power supply neededMeasure Voltage: DC 4.5-30V two-wire accessDisplay: Three digit 0.56" LED, Red colorRefresh Speed: Approx.300mS/timeHighest input:DC 30V (higher than 30v has the risk of burn up)Minimum input:DC 4.5V(below than 4.5V,measurement is inaccurate or does not show)Minimum Resolution:0.01V(<;10V)/0.1V(>10V)Resolution:1%1digitWorking Temperature:-2065Size:Approx. 48mm x 29mm x 22mm(L*W*H)Hole Size: Approx.46*27mm<;23mADC 4.5/4.7/530V Three WiresUltra-low cost, high precision to meet most of the application requirements.High precisionlow starting working voltage, red minimum 4.5V, green minimum 5.0V, blue minimum 5.0V.with reverse protection, anti-burn.Technical Parameters:Measuring range 0.00V-30.0VPower supply range red D
