White Cover DC 3.5-30V Voltage Current Meter DC 999mA 2A 5A 10A 20A 50A 100A 200A 300A 500A 1000A Voltmeter Ammeter Wide Range(Red-Red,999mA)

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.Technical Parameters: Dimension:48*29*21 mmSupply voltage:DC3.5 ~ 30V(Note:The maximum input voltage can not exceed 30V, or be burnt.)<;20mADisplay 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 dimension: 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.With a voltage calibration potentiometer, current calibration potentiometer, you can calibrate by yourself. The tolarance is absolutely exist.Good anti-interference ability, showing the refresh speed. With three wires,connection is convenient,used to monitor the battery voltage,can be also used for other products.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 negative, as shown below.Suitable for "more than 10A",must need a shunt: Suitable for "10A or less",no need a shunt: Working conditions: Operating temperature: -10 ~ +50 Working humidity: 10 ~ 80% (no condensation)Working pressure: 80 ~ 106kPaSun exposure: no direct
