Three-phase electric energy meter UEM100

DIN railpulse outputMID certified

Product Details UEM100 is the new high-performance three-phase energy meter, certified for operation up to 70°C. With a 4-DIN module design, it provides accurate measurement and full functionality even under high current loads. It supports direct connection up to 100 A per phase and communicates via RS485 Modbus RTU or M-Bus. The meter provides bidirectional measurement, compliant with MID Class B (EN 50470-3), making it suitable for billing and certified energy accounting. It measures key electrical parameters, which can be viewed via the integrated COM port. It’s compatible with 2-, 3-, and 4-wire networks, and ensures reliable measurements even under unbalanced load conditions. The device features two S0 outputs—one programmable and one fixed—supports up to four tariff management settings, and includes a metrological LED and sealable terminals for immediate reading and protection. Optional software is available for device management. Technical Specifications - Power supply: Power supplied from the voltage circuit.
