Single-phase energy analyzer with backlit LCD screen and integrated touchpad. Particularly suitable for active energy metering and cost allocation in applications up to 100 A (direct connection), with the possibility of dual tariff management. The energy to be measured is read via an RS485 Modbus or M-bus port. Can measure imported and exported energy or be programmed to only account for the measured energy. Housing for DIN rail mounting, with IP51 protection on the front. The analyzer optionally features a pulse output proportional to the active energy.
