LED Digital Voltmeter Ammeter DC 0-100V 300V 600V Panel Amp Volt Voltage Current Meter DC 10A Isolated Power Supply DC8-18V(Black Cover,DC0-100V)

AmmetersAttention:1,999mA, 2A, 5A, 10A, 20A,the shunt is built in.2,More than 20A,you must use a shunt to work,even 0.1A, or it will be burnt.3,More than 20A,the shunt is not built in,4,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:DC8-18V<;200mADisplay mode: 0.39 "LED, Red for voltage,Green for currentDimensions: 70 × 40 × 30 mmInstallation opening: 68 × 38 mmMeasurement rate: 500mS / timeMeasurement accuracy: 1% (± 2 digits) .Features:The difference bewteen thestandard meterand theisolation meter:(1) Standard meter:The negative of power supply and the testing side areconnected.It need a independent power supply.It can't be allowed more than two meters use one power supply.(2)Isolation meter:The negative of power supply and the testing side arenot connected.They are isolated.It can be allowed more than two meters use one power supply.The wide power supply range, with reverse polarity protection.Display voltage and current on thescreen at the same time.With a back cover,safe ,reliable and dustproof.The decimal point automatically shifted.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 five wires,connection is convenient,used to monitor the battery voltage,can be also used for other products.Meterpower supply: two-wire terminalsBlack wire: Negative power supply.Red wire: Positive power supply.Testing side:three-
