1PCS Digital Voltage red and Green Double LED Display Ammeter | [](Black,DC0-300V)

OhmmetersDigital voltmeter ammeter DC 100V 100A panel ampere voltage and current meter tester red and green dual LED display ammeter2. If the current exceeds 20A, a shunt must be used to work, even if it is 0.1A, otherwise it will burn out.(1) When two or more instruments are installed on one device. (2) When the power supply cannot be isolated.Supply voltage: 1. Standard meter: DC3.5~30V (Note: the input voltage cannot exceed 30V, otherwise it will burn) 2. Isolation meter: DC8-18VWorking current:<;20 mA;<;200 mADisplay mode: 0.39" LED, red represents voltage, green represents currentDimensions: 70 x 40 x 30 mmMounting opening: 68 x 38 mmMeasurement rate: 500mS/timeMeasurement accuracy: 1% (±2 digits)Meter power supply: two-wire terminalBlack wire: negative pole of power supply.Red wire: positive pole of power supply.Test terminal: three-wire terminalCOM: Test common terminal (COM is the common negative pole of the voltmeter and ammeter)V+: Test positive voltage inputA+: Test positive current input. It can only be connected to the negative pole of the load and the negative pole of the load power supply, as shown in the figure below.Applicable to "20A and above, a shunt is required:Voltage Range: Other: YB4835VASize: 70*40*30cmWorking temperature: -10~50 degreesAccuracy grade: 1% +/- 2 digitsPower supply: DC
