DC 0-100V 10A Dual Display Digital Voltmeter Ammeter Panel
DC 0-100V 10A Dual Display Digital Voltmeter Ammeter Panel
DC 0–100V 10A Dual Display Digital Voltmeter Ammeter Panel Gauge
Monitor voltage and current at a glance with this compact dual-display DC voltmeter ammeter. The bright 0.28" LED panel shows voltage in red and current in blue simultaneously, making it easy to track both readings without switching modes. Ideal for battery banks, solar setups, DIY power supplies, and any DC electrical project requiring accurate, real-time measurement.
Made in Mainland China.
Key Features
- Dual-color LED display: Red digits for voltage (0–100V DC), blue digits for current (0–10A DC) — both shown at once
- High accuracy: Voltage tolerance ±1%, current tolerance ±0.1% with auto-ranging at 0.01V / 0.01A resolution
- Fast refresh rate: 300ms update cycle keeps readings current and responsive
- Reverse-connection protection: Built-in safeguard against accidental wiring mistakes
- Compact panel-mount design: Body size 48 × 29 × 21 mm; cutout size 46 × 27 mm — fits neatly into enclosures and project panels
- Wide operating temperature: -10°C to 65°C for reliable use in varied environments
- Requires external DC power supply: 4–30V supply voltage (DC only; not for AC use)

Frequently Asked Questions
Q: Does this digital voltmeter ammeter work with AC power?
A: No — this panel meter is designed for DC circuits only. It measures DC voltage from 0–100V and DC current from 0–10A. Do not connect it to an AC power source, as this may damage the unit.
Q: Does the meter need a separate power supply to operate?
A: Yes. The meter itself requires an external DC power supply of 4–30V (via the thin red wire). If the meter supply voltage is the same as the load being measured, ensure the load voltage stays within the 4–30V range to avoid damage.
Q: How do I mount this voltmeter ammeter in my project panel?
A: The unit is designed for panel mounting. Cut a rectangular hole of 46 × 27 mm in your enclosure, slide the meter in, and secure it in place. The overall body dimensions are 48 × 29 × 21 mm, so it fits neatly in most standard project boxes and DIY enclosures.
Q: What is the accuracy of this dual-display panel meter?
A: The voltmeter ammeter offers a voltage tolerance of ±1% and an impressive current tolerance of ±0.1%, with auto-ranging resolution of 0.01V and 0.01A. The display refreshes every 300ms, providing near real-time readings.
