Mini Digital Voltmeter 0–100V DC — 0.39″ 3-Wire, Yellow Display

Mini Digital Voltmeter 0–100V DC — 0.39″ 3-Wire, Yellow Display

A compact 0.39-inch 3-digit LED digital voltmeter measuring 0–100V DC with a yellow display — 3-wire configuration with separate power supply and measurement inputs. Panel-mount design with a compact footprint ideal for bench power supplies, battery monitors, and electronics enclosures. No shunt resistor required — connect directly to the voltage to be measured. Resolution: 0.1V.

Key Specifications

• Measurement range: 0–100V DC | Resolution: 0.1V
• Accuracy: ±1% ±0.1V | Display: 0.39″ 3-digit LED (Yellow)
• Wiring: 3-wire (separate VCC, GND, and measurement input)
• Power supply: 4.5–5.5V DC (separate from measured voltage)
• Panel cutout: 45×26mm
• Compliance: RoHS compliant

3-Wire vs 2-Wire Voltmeters

• 3-wire (this model): Separate power supply — can measure voltages below 4.5V, more accurate
• 2-wire: Powers itself from measured voltage — simpler wiring but minimum ~4.5V measurement

Typical Applications

• DIY bench power supply voltage display
• Battery voltage monitor (12V, 24V, 48V systems)
• Solar panel and charge controller voltage display
• Electronics enclosure voltage indicator
• Arduino project voltage monitoring display
