DC 0-100V 10A Digital Voltmeter and Ammeter Dual Display
The dual-display voltmeter & ammeter is a compact DC measurement module that provides simultaneous readouts of voltage and current on two LED displays. It is designed to monitor DC systems up to 100 V and 10 A, making it suitable for power supplies, battery banks, solar installations or general DC circuits. The module integrates both measurement and display in a single small panel-mount unit, which simplifies wiring and installation.
When connected, the device reads the circuit’s DC voltage and current in real time, and displays them simultaneously: voltage on one LED display, current on the other. As the load or supply changes, the readings update automatically, giving immediate feedback. This allows users to observe changes in voltage under load, detect overcurrent conditions, or monitor battery charge/discharge in a straightforward way. The dual-display design means you don’t need separate instruments for voltage and current one module handles both.
Because of its small form factor and panel-mount design, the meter can easily be installed in power supply enclosures, battery boxes, DIY electronics projects, or control panels. Its direct-measurement up to 100 V and 10 A makes it versatile for hobbyist, automotive, solar, or small industrial DC circuits. The module’s simplicity no complex calibration or external sensors (for current, typically a built-in shunt) makes it accessible to hobbyists, technicians, or professionals wanting quick, continuous monitoring of DC voltage and current without bulky equipment.
Features:
- Dual LED display shows both voltage and current simultaneously.
- Measures DC voltage up to 100 V and current up to 10 A directly.
- Built-in current measurement shunt (no external shunt required for ≤ 10 A).
- Compact panel-mount size for easy integration into enclosures or devices.
- LED indicators (typically red for voltage, blue for current) easy to read even in low light.
- Low power consumption (meter draws < 20 mA).
