Three-phase electric energy meter DDSD858

wall-mountedRS-485multi-function

DDSD858/DTSD858 series three-phase electronic multi-function energy meter adopts large scale integrated circuit,digital sampling process technology and SMT manufacture. And it conforms to standard of IEC 62053-21-2003,IDT,IEC 62053-61-1998 and IEC 62053-22-2003,IDT. This meter can measure active,reactive electricity and max needs of each direct, and also has dual-485 communicate,manual and infrared weak up when power-off. And it has stable characteristic,convenient operate. Function feature 1)Time sharing metering Positive and negative active power (active measurement can be set),and storage data of present, last month,and last 2 months. 2)Time sharing metering Positive and negative reactive power (reactive measurement can be set),and storage data of present, last month,and last 2 months. 3)Measure - active and reactive total power,and storage the data of last 3 months. 4)Time sharing metering Four quadrant reactive power and storage the data of last 3 months. 5)Time sharing metering Positive and negative active power and reactive power and storage the data of last 3 months. 6)Max needing cycle 5 min,10 min,15 min,30min,60min.(selectable)
