    Application

    The SDM72-Bi energy-meters “with a white back-lighted LCD screen for prefect reading” are used to bi-directionally measure renewable energy. The unit measures and displays import and export active energy (kWh) and Power (W). The resettable partial energy is provided, so the user can easily check the energy imported and energy exported during a certain period. An optional version provide super capacitor to keep the LCD display on when the external power is off.
