The COM-VAM02 is a compact and precise digital DC volt/ammeter designed for accurate monitoring of voltage and current in low-voltage systems. With its integrated dual display, external shunt resistor, and calibration function, it offers a dependable and user-friendly solution for laboratories, industrial setups, and mobile applications.

The device operates from 3.5 – 30 V DC and measures voltages up to 100 V DC and currents up to 50 A DC with a fine resolution of 0.1 V / 0.1 A. Two separate 3-digit LED displays clearly present both measured values — the red display for voltage and the green display for current. Each display features a digit height of 0.28″, ensuring excellent visibility even in bright environments.

By using an external precision shunt resistor, the COM-VAM02 achieves safe and stable high-current measurements without excessive internal heating or voltage drop. The integrated calibration potentiometer allows the current reading to be fine-tuned, ensuring long-term accuracy even after extended use.

With a refresh rate of 500 ms and an accuracy of ±1 % + 2 digits, the device delivers fast, stable, and reliable readings. Thanks to its compact size (48 × 29 × 22 mm) and wide operating temperature range (–10 °C to +60 °C), it can be easily installed in control panels, test benches, or portable systems.

The COM-VAM02 is the ideal solution for anyone needing a precise, robust, and affordable dual measurement instrument for DC voltage and current — combining ease of installation with dependable performance in everyday use.
