DDS877 , DDS48 type electronic single phase energy meter
Application :
DDS877 , DDS48 type electronic single phase energy meter is the most advanced static electronic meter in China. The meter designs use large-scale integrated circuit, high reliability step motor, it can meter the AC single-phase active energy (voltage rating: 220V; frequency 50Hz), positive and negative two directions and accumulates in one direction.
It also has the function of anti-tamper. It adopts the optocoupler output signals, and used for directing the energy with the power line carrier light-emitting diodes, and it is easy to be managed.
