Vender 0.36 inch DC4-40V Digital Voltmeter Display Volt Meter Gauge Panel Tester al mejor precio

Feature: 1. This voltmeter has a volume of 0.36 inches, a range of DC 0-40V, 2-wire access, breaking the conventional voltmeter. It is the latest design. It can work directly in 5V, 9V, 12V, 24V circuits without voltage regulation. 2. Equipped with two wiring, easy access to the car/battery car/motorcycle internal line, with reverse connection protection function, wiring will not burn. 3. It can be used to monitor battery voltage and master battery voltage status in time. It can also be used for voltage measurement of other products. 4. Ultra-low starting voltage, red minimum 2.5V, green minimum 2.7V, blue minimum 3.0V. If conditions permit, the recommended voltage range DC 4V-30V is the best. 5. Good product stability and high measurement accuracy. 6. Appearance adopts standard size, easy to install. 7. Power supply adopts polar protection circuit. Specification: Product model: HW-804 Input voltage: DC4-40V Working Current: <20mA Working temperature: -10~+65℃ Working humidity: 10-80% (no condensation) Working Pressure: 80-106 kPa Sunshine exposure: no direct exposure Measurement rate: ≥320mS/time Measurement accuracy: 3% Input impedance: > 100K ohm Lead length: 15cm/5.9'' Display mode: 0.36 "LED, red, blue, green (color optional) Installation hole: central hole spacing: 27.5 mm/1.08''; aperture: 3 mm Size: 22.5*14.4*9mm/0.88*0.56*0.35'' (excluding installation ears) Packing weight: 5g Warm Tips: The maximum input voltage of the two wires should not exceed 40V, otherwise there is a risk of burnout. Use voltage within 40V (many peers can only use less than 30V). Note: Please allow 1-3mm differs due to manual measurement. Due to the different display and different light, the picture may not show the actual color of the item. Thanks for your understanding. Included: 1 X 0.36 inch DC4-40V Digital Voltmeter
