Product

The D9 series rail-mounted meter is a highly integrated compact electric energy meter. It mainly adopts the DIN35 installation method, which can accurately and directly measure the electric energy consumption of the load in the three-phase/single-phase AC power grid. Its performance meets the relevant technical requirements of GB/T17215.321-2021, and has certain functional expansibility. It is suitable for the sub-item measurement of electric energy in government agencies and large public buildings, and can also be used for electric energy management assessment in enterprises and institutions.
