10pcs LED Digital Voltage Current Dual Meter DC 0-100V 0-100A Ampere Panel Meter Voltmetro DC Volt Amp Tester(Red-Blue)

AmmetersAttention:1,999mA, 2A, 5A, 10A,the shunt is built in.2,More than 10A ,you must use a shunt to work,even 0.1A, or it will be burnt.3,More than 10A,the shunt is not built in4,Because the 24V battery charge full of floating voltage may be more than 30V, so "no" recommended direct use 24V battery.5,In the following circumstances, it is strongly recommended to choose: isolation meter (isolated power supply meter):(1) When two or more meters are installed on a device. (2) Can not be isolated power supply.Technical Parameters:Supply voltage: 1.Standard:DC3.5 ~ 30V(Note:The maximum input voltage can not exceed 30V, or be burnt.) 2.Isolation meter:DC8-18V<;20mA; 2.Isolation meter: 200mADisplay mode: 0.28 "LED, single color or double color:(red-red): Both voltage and current are red color(red-blue): Voltage is red,current is blue. Installation opening: 45.5*26.5 mmMeasurement rate: 500mS / timeMeasurement accuracy: 1% (± 2 digits) Features:The wide power supply range, with reverse polarity protection.Display voltage and current on the screen at the same time.The decimal point automatically shifted.The testing side and the power supply side of the negative is connected(except the isolation meter).Good anti-interference ability, showing the refresh speed. With five wires,connection is convenient,used to monitor the battery voltage,can be also used for other products.Black wire: Negative power supply.Red wire: Positive power supply.Testing side: three-wire terminalsCOM(black wire): Test common terminal(The COM is commond negative of voltmeter and ammeter)V +(red wire): Test positive voltage inputA +(yellow wire): Test positive current input. It can only be connect the load negative and load power negativeSuitable for "more than 10A",must need a shunt:Only suitable for electric bicy
