The COM-VAM03 is a compact and easy-to-use digital DC volt/ammeter designed for accurate and reliable measurement of voltage and current in low-voltage systems. Featuring an integrated shunt resistor and a dual LED display, it offers a space-saving and maintenance-free solution for laboratory setups, power supplies, model building, and mobile DC projects.

The device operates from a supply voltage of 3.5 – 30 V DC and measures voltages up to 33 V DC and currents up to 9.99 A DC simultaneously. Both measured values are shown on two bright 3-digit LED segment displays with a digit height of 0.28″ per digit. The red display indicates voltage, while the green display shows current, ensuring excellent readability under all lighting conditions.

Thanks to the integrated shunt, no external resistor or wiring is required for current measurement, allowing quick and clean installation. The meter provides a resolution of 0.01 V (0.1 V)/ 0.01 A and a measurement accuracy of ±1 % + 2 digits, making it ideal for monitoring small DC systems and electronic projects without the need for manual calibration.

With a refresh rate of 500 ms, a compact size of 48 × 29 × 22 mm, and an operating temperature range from –10 °C to +60 °C, the COM-VAM03 combines functionality, reliability, and convenience in one compact unit.

This makes it a cost-effective and practical solution for voltage and current monitoring in low-voltage DC circuits, power supply testing, or educational applications.
