Multicolor LED Digital Voltage Display Panel - 5V - 120V Two Wire (Red)

Introducing the Digital Voltmeter DC 4.5V to 30V — an essential tool for enthusiasts and professionals alike, designed for accurate voltage measurement across a variety of applications such as motorcycles, cars, and electromechanical devices.

🛠️ Measurement Range: This versatile voltmeter measures voltages from 0V to 30V with precision and accuracy. For more extensive applications, it can also handle input voltages up to 100V when using a three-wire connection. However, caution is advised as exceeding 30V may lead to permanent damage to the device.

💍 Operational Features: The digital voltmeter requires an external DC voltage supply ranging between 5-30V to function effectively. The wiring is straightforward: the black wire serves as the common negative, the white wire connects to the voltage being measured, and the red wire connects to the working power supply. This simple setup ensures ease of installation for various electronic and automotive applications.

🛠️ Accuracy: Engineered for precision, this voltmeter boasts an allowable error of ±1%. When measuring voltages of 10V or greater, the tolerance reduces to ±0.3V; for voltages below 10V, the allowable error shrinks to ±0.10V. This level of accuracy makes the voltmeter a reliable choice for professionals who demand precision in their readings.

💍 Input Characteristics: With an input impedance greater than 100K Ω, this voltmeter offers minimal load on the circuit being tested, preserving the integrity of the system. The device operates with low current draw — only 23mA for the red display, 18mA for green, and 13mA for blue — ensuring it remains energy-efficient during use.

💍 Display Specifications: Featuring a bright three-digit 0.56" LED digital display, the voltmeter is designed to be easily readable in various lighting conditions. Available in multiple colors including red, green, blue, orange, and white, the display allows users to choose according to their preference or environment.

📦 Dimensional Insights: The compact design, measuring 48 x 29 x 22 mm, fits seamlessly into confined spaces without compromising on readability. The mounting hole dimensions of 46 x 27 mm make installation a breeze in panels or dashboards.

Temperature Range: Built to withstand varying environmental conditions, the voltmeter operates efficiently in temperatures ranging from -10℃ to 65℃, making it suitable for both indoor and outdoor use.

💍 In summary, the Digital Voltmeter DC 4.5V to 30V is a robust, accurate, and user-friendly device, ideal for measuring voltage in cars, motorcycles, and a wide range of electronic applications.
