The COM-VAM01 is a versatile and precise digital panel meter for simultaneous measurement of DC voltage and current. Designed for reliable use in laboratory, industrial, and mobile DC systems, it offers a wide measuring range and easy integration into a variety of applications such as power supplies, battery systems, or solar controllers.

The device supports an operating voltage of 3.5 – 30 V DC, measures voltages up to 100 V DC, and currents up to 100 A DC with a fine resolution of 0.1 V / 0.1 A. Both measured values are displayed separately on bright, high-contrast 3-digit LED segment displays, featuring 0.28″ digit height per display. The red display indicates voltage, while the green display shows the current.

For high-current measurement, the COM-VAM01 uses an external precision shunt resistor, allowing safe, low-loss measurement even at high load currents. The included calibration potentiometer enables fine adjustment of the current reading to ensure long-term measurement accuracy.

With a refresh rate of 500 ms and a measurement accuracy of ±1 % + 2 digits, the device provides fast and reliable readings for real-time monitoring. The compact design (48 × 29 × 22 mm) and lightweight construction make it easy to integrate into front panels or enclosures, while the wide operating temperature range (–10 °C to +60 °C) ensures stable performance under demanding conditions.

Thanks to its four-wire system for current measurement and an additional voltage-sense wire, installation is straightforward and secure. This makes the COM-VAM01 a robust, precise, and user-friendly dual display meter, ideal for engineers, technicians, and developers who require a dependable measurement solution for DC applications.
