ADF400L multi-circuit energy meter

The ADF400L multi-circuit energy meter can implement direct access measurements of 12 three-phase channels or 36 single-phase channels, or mixed measurements of 12 three-phase channels with transformer access measurement, direct access, and transformer access through module combinations. Its high accuracy, centralized installation, centralized management, and high installation flexibility provide advantages for municipalities, schools, and businesses, including interference prevention and other benefits. A prepaid option is now available.
