DDS 877 single phase electronic energy meter
Conformed Standards:
1 Chinese GB/T 17215-2002 Alternating Current Static Watt-hour Meters for Active Energy (class 1 and 2)
2 Chinese GB/T 17215.321-2008 Electronic Meters for active energy (class 1 and 2)
3 International standards IEC 61036-2000, IEC 62053-21:2003
Application:
DDS877 electronic single-phase electric 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.
