DC 440V Voltmètre numérique bricolage stable haute précision de mesure Panneau de voltmètre numérique LED de taille standard Bleu - Générique

Feature:1. [New Design] This LED digital voltmeter appearance using standard size, easy to install, volume 0.36 inch, range DC 040V, 2 wires access, breaking the conventional voltmeter, is the latest design.2. [2 Wiring] LED voltmeter is equipped with 2 wiring, wiring length is about 10cm/3.9in. 2 wiring use the highest input voltage can not exceed 40V, the use of voltage to be within 40V, otherwise there is a danger of burnout.3. [Voltage Range] The voltmeter is 3V ultra low starting voltage, good stability. If the conditions allow, the recommended voltage range DC 430V best, can work directly in 5V, 9V, 12V, 24V and other circuits, without voltage regulation.4. [Reverse Connection Protection] The voltmeter has high measurement accuracy, and the power supply adopts polarity protection line, with reverse connection protection function, the line will not burn when connected in reverse.5. [Use Way] voltmeter convenient access to the car, battery car, motorcycle car line. Used to monitor the battery voltage, battery voltage state in a timely manner, can also be used for other products voltage measurement purposes.Specification:Item Type: VoltmeterMaterial: PCBProduct Size: Approx. 33x14.1x9mm/1.30x0.56x0.35inDisplay Mode: 0.36in LEDInput Voltage: DC 4-40VOperating Current: <20mAOperating Temperature: -10 to +65Working Humidity: 10-80% (no Condensation)Working Pressure: 80-106kPaMeasurement Rate: 320mS/ timeDisplay Accuracy: 0.01Error: 1%Input Impedance: >100K OhmLead Length: Approx. 13cm/5.12inMounting Hole: Center Hole Distance Approx. 27.5-28mm/1.08-1.10in, Aperture Approx. 3mm/0.12in.Package List:1 x VoltmeterNote:All data are measured manually, and there are certain errors in the measurement results.
