aFe Power 2.5V-30V Mini DC Voltmeter 5-Pack 0.28" LED

Compact five-pack DC voltmeter

This aFe Power set supplies five miniature digital DC voltmeters in red, yellow, green, blue and white. Each unit measures a specific low-voltage range between 2.4 V and 30 V with a stated accuracy of 3% plus or minus one digit. The 0.28 inch LED display updates every 200 ms and draws less than 30 mA while operating. Builders monitoring multiple battery banks or accessory circuits can assign a colour to each circuit for quick identification.

Steady monitoring across the range

The meters sample voltage at a fixed 200 ms interval, so readings remain consistent during prolonged observation rather than only during brief checks. Accuracy holds at 3% across the full span from the lowest start threshold up to 30 V, letting you track gradual discharge or charge curves. Operating temperature spans minus 10 to plus 65 degrees Celsius with humidity tolerance from 10 to 80 percent, so extended use in engine bays or outdoor enclosures stays within spec.

Low draw and simple mounting

Each tester consumes under 30 mA, imposing minimal load on the circuit under test. The housing measures 22.5 by 10 by 7 mm and fits a 23 by 10 mm cutout, allowing flush panel installation without large openings. No external power supply is needed because the unit is powered from the measured voltage itself. The package contains only the five voltmeters; buyers needing wiring harnesses, fuses or mounting hardware must source those separately.
