Product Overview
The YD2202 is engineered to monitor electrical parameters such as voltage, current, active/reactive power, power factor, frequency, and energy consumption. It features an intuitive LCD for real-time display and uses RS-485 communication for data transmission. This makes it suitable not only for conventional industrial panels, but also for IoT gateways, building automation systems, and energy monitoring platforms.
With measurement up to 6A, high measuring energy range (999,999.99 MWh), and support for both single-phase and three-phase configurations, the YD2202 is flexible enough for a wide range of applications. Its robust design performs stably in industrial environments.
