1PCS DC 3.5-30V 100A LED Digital Voltmeter Three-Wire(Red-Blue)

Current ProbesDC 3.5-30V 100A Voltmeter Amperemeter Blue + Red LED Ampere Dual Digital Voltmeter Meter Three Wire DC Ampere Voltmeter2. If the current exceeds 10A, a shunt must be used to work, even if it is 0.1A, otherwise it will burn out.4. Because the floating charge voltage of a 24V battery after being fully charged may exceed 30V, it is "not" recommended to use a 24V battery directly.Size: 48*29*21mmSupply voltage: DC3.5~30V (Note: The maximum input voltage cannot exceed 30V, otherwise it will burn out.)<;20 mADisplay mode: 0.28” LED, single or dual color: (Red-Red): Voltage and current are both red (Red-Blue): Voltage is red, current is blue.Installation size: 45.5*26.5mmMeasurement rate: 500mS/timeMeasurement accuracy: 1% (±2 digits)Test terminal: three-wire terminalCOM (black line): test common terminal (COM is the common negative pole of the voltmeter and ammeter)V+ (red wire): test positive voltage inputA+ (yellow line): 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 below:For "above 10A", a shunt is required:Dimensions: 48x29x21mmOperating temperature: -10 to +50 degreesPower supply voltage: DC 3.5-30VAccuracy grade: 1% +/- 2 digitsModel: YB27VADisplay Type: Numbers onlyTest voltage: DC 3.5-30VTest current: DC100AMounting hole: 45.5x26.5 mmFeatures: Three lines
