DC 0-100V 300V 600V LED Digital Voltmeter Voltage Meter Volt Instrument Tool 3-Wire Red Display Volt Panel Meter Monitor(Blue,DC0-300V)

AmmetersAttention:1. The power supply voltage of the instrument should not exceed 30V, and enough safety voltage space should be reserved;3. DC0- 100V, DC0-300V: When the measured value is less than 9.9V, only two digits will be displayed; when the measured value is greater than 9.9V, only three digits will be displayed.4. DC0-600V: When the measured value is less than 99V, only two digits are displayed; when the measured value is greater than 99V, only three digits are displayed.5. This meter has no case, the PCB board is exposed.Technical Parameters: Dimension:33*15mmLead length: >120mm<;20mAPower Supply:DC3.3-30VTestvoltage:DC0~10V/30V/100V/300V/600V/1000VDisplay mode: 0.36 "LED with red/blue/green digitsMeasurement rate: 500mS / timeLead length: >120mmMeasurement accuracy: 1% (± 2 digits)Features: With three wires,the wiring is simple, the installation is convenient.When there is a small tolerance, you can calibrate by the potentiometer on the circuit board.With polarity protection function for meter power supply.With three wires, can be connected to cars,e-bikes or motorcycles.Connection Diagram: Red wire : Power supply Positive terminal Black wire: Public Negative terminal(Power supply and test negative terminal)Yellow wire: Testing terminalWorking conditions:Operating temperature: -10 ~ +50 Working humidity: 10 ~ 80% (no condensation)Working pressure: 80 ~ 106kPaSun exposure: no direct exposure
