27C LED Digital Ammeter DC 10A 20A 50A 100A 200A 300A 500A 75mV mA Current Meter Monitor Ampere Gauge Amp Panel Tester 999 uA(Black Cover-Standard,DC999uA(Direct Test))

AmmetersSupply voltage:1.Standard:DC4.5 ~ 30V(Note:The maximum input voltage can not exceed 30V, or be burnt.)2.isolation meter:DC8-18VOperating current:<;20mA; <;200mATest current:DC100uA/1mA/10mA/100mA/1A/5A/10A/20A (Direct test) DC20A/30A/50A/100A/200A/300A/5000A/1000A (Must connect to external shunt)Display mode0.56 "LED with red/blue/green digitsMeasurement accuracy1% (± 2 digits)Measurement rate 500mS / timeDimension: 48*29*21 mmMounting hole: 45.5*26.5mmFeatures: The difference bewteen the standard meter and the isolation meter:(1) Standard meter:The negative of power supply and the testing side are connected.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 are not 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.DC20A,The decimal point automatically shifted.The testing side and the power supply side of the negative is connected(except the isolation meter).With a current calibration potentiometer, you can calibrate by yourself. The tolerance is absolutely exist.Good anti-interference ability, showing the refresh speed.With four wires,connection is convenient,used to monitor the battery current,can be also used for other products.Working conditionsOperating temperature 10 +50 Working humidity: 10 ~ 80% (no condensation)Working pressure: 80 ~ 106kPaSun exposure: no direct exposure
