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

The Miniature 0.36-inch 2-Wire LED Digital Voltmeter is an ultra-compact, highly precise voltage measurement module designed for real-time monitoring of DC power systems. Operating on a wide voltage range from DC 2.7V to 32V, this self-powered panel meter requires no external power source, drawing its operating current directly from the target voltage source being measured. It features a bright, high-visibility 3-digit red LED display that is easy to read even in low-light environments.

Engineered with variable precision, the voltmeter automatically shifts its decimal point to provide maximum resolution (0.01V resolution for voltages under 10V, and 0.1V resolution for voltages above 10V). Equipped with built-in reverse polarity protection, this module prevents damage from accidental incorrect wiring, making it exceptionally safe and reliable for students, makers, and professional engineers. It is highly compatible with battery packs, custom bench power supplies, RC vehicles, solar setups, and e-bike monitoring systems.

Features:

• Two-Wire Operation: Simple red and black wire interface; requires no external power supply.
• Variable Precision: Automatic decimal point shifting ensures maximum resolution across the entire measurement range.
• Reverse Polarity Protection: Built-in safety circuitry prevents module burnout if wires are connected backward.
• High Visibility: Features a bright 0.36-inch 3-digit red 7-segment LED display.
• Compact Mounting: Designed with integrated mounting ears for easy installation into custom enclosures or panels.
• Wide Compatibility: Perfect for monitoring lithium-ion batteries, lead-acid batteries, and DIY power supplies.
