Digital Volt Meter 0–100V 0.28 Inch
The Digital Volt Meter 0–100V 0.28 Inch is a miniature digital panel meter designed for real-time DC voltage measurement. Featuring a bright 0.28-inch LED display, it provides clear voltage readings while occupying minimal panel space, making it suitable for compact electronic enclosures and control panels.
This panel voltmeter measures DC voltages from 0V to 100V, making it ideal for monitoring 12V, 24V, 36V, 48V, and other DC power systems. Most versions use a 3-wire connection, allowing the display to remain powered while accurately measuring the input voltage across a wide range. Typical models offer 0.1V resolution, approximately ±1% measurement accuracy, and a fast display refresh rate for stable, real-time readings.
Its compact panel-mount design makes installation quick and straightforward in battery chargers, solar power systems, DIY electronics, automotive projects, laboratory power supplies, and industrial control equipment. Low power consumption and a durable ABS housing make it suitable for continuous operation.
