0.36 Inch 2-Wire LED Digital Voltmeter DC 2.7V-32V Blue

The Miniature 0.36-inch 2-Wire LED Digital Voltmeter is an ultra-compact, high-precision voltage measurement module designed for real-time monitoring of DC power systems. Operating on a wide voltage range from 2.7V to 32V DC, this self-powered panel meter requires no external power source, drawing its operating power directly from the target voltage source being measured. Featuring a bright, high-contrast blue 3-digit 7-segment display, it ensures excellent readability even in low-light environments.

This digital voltmeter is engineered with built-in reverse polarity protection, preventing damage to the module if the connections are accidentally swapped. It also features an automatic decimal point shifting mechanism, displaying two decimal places for voltages below 10V (e.g., 9.99V) and one decimal place for voltages above 10V (e.g., 10.5V) to maximize measurement resolution. It is highly compatible with lithium-ion batteries, lead-acid batteries, RC vehicles, solar power setups, and custom bench power supplies, making it an indispensable tool for makers, students, and electronics engineers.

Features:

• Two-Wire Self-Powered Design: Measures and powers itself from the same two wires, eliminating the need for an auxiliary power supply.
• Wide Measurement Range: Accurately measures DC voltages from 2.7V up to 32V.
• Reverse Polarity Protection: Integrated safety circuitry prevents the module from burning out if wired backwards.
• Variable Precision Resolution: Automatically shifts the decimal point to provide 0.01V resolution below 10V and 0.1V resolution above 10V.
• Bright Blue LED Display: Clear 0.36-inch 3-digit display offers high visibility and low power consumption.
• Easy Installation: Equipped with convenient side mounting tabs for secure panel integration.

Package Includes:

1 x 0.36 Inch 2-Wire LED Digital Voltmeter DC 2.7V-32V (Blue)
