DC 0–100V · 0–10A · Red & Blue LED Display
Built-in Shunt · Panel Cut-out Ready
This compact dual-display LED panel meter simultaneously shows DC voltage in red and DC current in blue, giving you an instant, at-a-glance readout of both parameters without the need for a separate instrument. Designed for flush panel mounting, it drops straight into a 45.5 × 26.5 mm cut-out and locks in place with the included rear clips — no tools, no fuss.
The built-in shunt handles up to 10 A of direct current, so no external shunt resistor is needed for this range. Voltage measurement spans 0–100 V DC with 0.1 V resolution, and the meter powers itself from the same supply it's monitoring (4–30 V operating range), keeping wiring simple and tidy. With a refresh rate of ≥500 ms, readings update smoothly in real time.
Key Features Simultaneous voltage & current display on one screen Red LED digits for voltage — instantly distinguished Blue LED digits for current — clear colour coding Built-in 10A shunt — no external component needed DC 0–100 V voltage measurement range DC 0–10 A current measurement range High accuracy: ±1% (±1 digit) 0.1 V voltage resolution / 0.01 A current resolution Self-powered from measured supply (4–30 V) Ultra-low self-consumption — under 20 mA Bright 0.28″ LED digits — readable in any light Fast refresh rate ≥500 ms — real-time readout Panel cut-out mount: 45.5 × 26.5 mm Compact 48 × 29 × 22 mm body Two wiring harnesses for clean installation Wide operating temp: −10 °C to +65 °C Wiring GuideThis meter uses two separate wire harnesses. The thick wires carry the measured current (in-line with your load). The thin wires power the meter's electronics. Connect as follows:
Thick RED Current IN (+) from supply positive Thick BLACK Current OUT (−) to load / GND Thin YELLOW Voltage sense — connect to measured +V Thin RED Meter power supply positive (4–30V) Thin BLACK Meter power supply negative / GND ⚠ Important: The meter's operating supply must be 4–30 V DC. If the supply being measured exceeds 30 V, use a separate 5–30 V source to power the meter electronics. Do not connect supply voltage above 30 V to the thin power wires — this will permanently damage the unit. The thick current wires can handle the full 0–10 A range directly.
