Low Voltage Transformers1pc DIY DC100V 10A Voltmeter Ammeter Blue Red Dual Amp Volt Voltage Current Meter Gauge Tester Panel Digital LED Display for CarSpecifications:Working voltage:4.5-30V DCNote: The maximum input voltage can not exceed 30V, otherwise there is the danger of burningWorking current:20mADisplay: 0.28" Two color blue and redMeasuring range: DC 0-100V 0-10AMinimum resolution (V): 0.1VRefresh rate: 100mS / timesMeasure accuracy: 1% (± 1 digit)Minimum resolution (A): 0.01AOperating temperature: -15 to 70° cWorking pressure: 80 to 106 kPasize :47×28×16 mm/1.85*1.10*0.63"Net Weight:19 gWeight:29 gPackage Included:1*Voltmeter AmmeterFeature:Reverse Connect ProtectionRange: DC3.0-30V (No need aditional power)Display: Three 0.56'' LED digital tubeDisplay color: redRefresh rate: about 500mS / times<;2 times the range)Resolution: 1% +1 digitPower Supply: DC3.0-30V (with the input common-line)Operating temperature: -10°c~ 65°c1, the voltmeter wiring is simple, only need to pick two lines, the table reversal protection, reverse does not burn.2, the voltmeter start voltage is low, the red just 2.5V, just 2.7V Green, the blue just 3.0V will be able to measure correctly, start with the of two-wire voltmeter voltage is the lowest anywhere in the world. This will greatly facilitate the use of the lithium battery, 18650 battery users. When the voltage is lower than 3.5V, the display brightness diminishes, but does not affect the correct measurement.3, in order to achieve optimum measurement accuracy, the voltmeter will be different according to the measured voltage automatically move the decimal point position. Measure the voltage below 10V, displayed after the decimal point two; 10V voltage measurements displayed after the decimal point one. That is able to take care of the battery user needs, but also cater to the needs of the higher voltage measurement on the measurement accuracy.4, the voltmeter can be used for motorcycles, cars and other monitoring battery voltage, timely grasp battery status. Other voltages can also be used for measurement purposes.
