DC Ampere Meter VoltmeterDC0~100V 20A Dual Display Integrated Voltage Ampere Meter Voltmeter DC Ampere Meter DC Dual Meter

Note: Power supply voltage (non-isolation meter): DC3.5 ~ 30V (wide range), note: maximum input voltage should not exceed 30V, otherwise there is risk of burning The watch head of 20A _ built-in shunt Since a 24V battery may have a floating voltage of more than 30V after it is filled, it is recommended that the "no" supply it directly with 24V batteries In the following cases, it is strongly recommended that: isolation meter (isolation power supply meter) When two or more meters are installed in a device, they cannot be alone, independent, or isolated when power is supplied Connection method: This meter is equipped with five lines, please find professionals strictly according to the following wiring diagram, if any questions, please feel free to contact customer service: Meter head power supply: two-wire socket Fine _ black line: meter head power supply Fine _ red line: power supply to watch head is positive (note, the voltage between fine red and black line cannot exceed 30V) Isolation meter (isolated power supply): The meter head power supply end and the test end are completely insulated and isolated from each other, can share one power source in multiple meters, "no need" is worried about all kinds of interference problems caused by sharing the power supply, suitable for the factory aging test stand, test stand, or other equipment requiring more than one meter head Power supply voltage: DC8-18V
