DC Voltage Current Meter DC 0-50A 100A 200A 300A 500A Voltmeter Ammeter Amp Volt Panel Meter DC 0-100V 300V 600V(Black Cover,DC0-300A 75mV,DC0-100V)

AmmetersTechnical Parameters:Display 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 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. Display voltage and current on the screen at the same time.Use the SMT technology,so consistency is very good.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.Working conditions:Operating temperature: -10 ~ +50 Working humidity: 10 ~ 80% (no condensation)Working pressure: 80 ~ 106kPaSun exposure: no direct exposure
