ORNO OR-WE-524 Single-Phase Bi-Directional Energy Meter 100A MID DIN Rail

The OR-WE-524 is a single-phase electronic energy meter for direct measurement of active and reactive energy in a single-phase system. It operates bi-directionally, recording both consumed and returned energy, and carries MID 2014/32/EU approval. The meter mounts on a DIN TH-35mm rail and occupies a single module width.
