0.28inch 3.5-30V Two Wire DC Voltmeter Red

The 0.28inch 3.5-30V Two Wire DC Voltmeter is a small digital panel meter with a red 0.28 in LED readout that shows DC voltages from 3.5 V to 30 V. It has only two wires: the meter takes its power from the same voltage it is measuring, so there is no separate supply to connect. It is a simple way to add a live voltage display to batteries, chargers, power banks and bench supplies.

0.28inch 3.5-30V Two Wire DC Voltmeter Applications

• Battery voltage monitors for 12 V and 24 V systems
• Adjustable DC power supplies and buck or boost converters
• Solar charging setups and power banks
• Car, bike and robot battery packs
• DIY bench supplies and project enclosures

What's in the Box

• 1 × 0.28 in red two-wire DC voltmeter

Tip: Connect the positive wire (usually red) to + and the negative wire (usually black) to −. Because the meter powers itself from the input, it cannot read below 3.5 V; to measure from 0 V, use a three-wire voltmeter that has a separate supply.
