DC 0-100V 10A Digital Voltmeter Ammeter Dual LED Panel Meter
DC 0-100V 10A Digital Voltmeter Ammeter Dual LED Panel Meter
DC 0-100V 10A Digital Voltmeter Ammeter – Dual Display Panel Meter
Monitor DC voltage and current simultaneously with this compact, high-accuracy dual-display digital voltmeter ammeter. Featuring a bright 0.28" dual-color LED display — red for voltage, blue for current — this panel meter makes it easy to keep a close eye on your DC circuits, battery banks, solar setups, and DIY electronics projects at a glance.
Key Features
- Dual simultaneous readings: Displays DC voltage (0–100V) and current (0–10A) at the same time in two distinct colors for instant identification.
- High accuracy: Voltage tolerance ±1%, current tolerance ±0.1% — auto-ranging resolution of 0.01V / 0.01A.
- Fast refresh rate: 300ms update cycle ensures near real-time readings.
- Compact panel-mount design: Body size 48 × 29 × 21 mm with a 46 × 27 mm mounting hole — fits easily into enclosures, panels, and DIY builds.
- Reverse-connection protection: Built-in safeguard helps protect the meter from accidental wiring errors.
- Wide operating temperature: Reliable from -10°C to 65°C for indoor and outdoor installations.
- DC only: Requires a 4–30V external supply voltage (separate from the measured load when load voltage exceeds 30V).

Frequently Asked Questions
Q: Can this digital voltmeter ammeter be used with AC power systems?
A: No — this panel meter is designed for DC circuits only. It measures DC voltage from 0–100V and DC current from 0–10A. It should not be connected to AC power systems.
Q: Does the meter need a separate power supply to operate?
A: Yes. The meter requires an external DC supply of 4–30V to power the display. If the meter's supply and the load share the same source and the load voltage is within 4–30V, the same supply can be used. If your load voltage exceeds 30V, a separate 4–30V power source is required for the meter itself to avoid damage.
Q: How do I mount this voltmeter ammeter into a panel?
A: Cut a rectangular hole of 46 × 27 mm in your panel or enclosure, insert the meter from the front, and secure it with the included clips or friction fit. The total body size is 48 × 29 × 21 mm, so the bezel will sit flush against the panel surface.
Q: What do the red and blue LED displays show?
A: The red LED digits display the measured voltage, while the blue LED digits display the measured current. Both readings are shown simultaneously, making it easy to distinguish values at a glance without confusion.
