0.28inch 3.5-30V Two Wire DC Voltmeter Blue

The 0.28inch 3.5-30V Two Wire DC Voltmeter is a small digital panel meter with a blue 0.28 inch LED display that reads DC voltages from 3.5 V to 30 V. It needs only two wires because it powers itself from the voltage it measures: red goes to positive and black to negative. That makes it a quick way to show the voltage of batteries, power supplies and chargers in DIY projects.

0.28inch 3.5-30V Two Wire DC Voltmeter Specifications

• Measuring range: 3.5–30 V DC
• Display: 0.28 inch blue LED digits
• Resolution: 0.01 V below 10 V, 0.1 V from 10 V up
• Wiring: 2 wires, red (+) and black (−)
• Power: taken from the measured circuit, no separate supply needed

0.28inch 3.5-30V Two Wire DC Voltmeter Applications

• Battery level display for 12 V and 24 V battery packs
• Voltage readout on DIY bench power supplies
• Monitoring 12 V systems in cars, boats and caravans
• Solar panel and charge controller monitoring

What's in the Box

• 1 × two-wire DC voltmeter, blue display

Tip: Because the meter runs on the voltage it measures, it cannot read below about 3.5 V; for readings down to 0 V use a three-wire voltmeter with its own supply. Never connect it to more than 30 V.
