High-precision 4P single-phase energy meter DDS1891, DIN rail mounted electricity meter

Discover our DDS1891 single-phase electronic active energy meter for DIN rail mounting, an innovative and high-performance measuring device. This brand-new meter stands out for its exceptional long-term reliability, compact and lightweight design, aesthetic appeal, and ease of installation. Designed to operate directly on a single-phase AC network with a nominal frequency of 50 Hz, it accurately and directly measures the active energy consumption of the load. It incorporates cutting-edge microelectronic technologies, utilizing large-scale integrated circuits, advanced digital techniques, and SMT (Surface Mount Technology), ensuring both performance and a compact design. Installation is simplified thanks to the standard 35 mm DIN rail, compliant with DIN EN50022. An extendable terminal cover is included for optimal protection and safety during use. The meter operates via direct connection and offers a choice of two wiring types: S-type wiring in the standard configuration, and U-type wiring as an option.
