 >> Summary : 

DDSY39 (LED) single-phase prepayment static energy met er is which adopts based on special large-scale integrated circuit and SMT technology, adopting industrial elements and components with long lifetime introduced form abroad. It preserves data under power-off situation. This product conforms to IEC62055-21-2005 & GB/T18460: Electricity metering, prepayment systems. and IEC62053 & GB/T18460.3- 2001: class 1 and class 2 static AC active watt-hour meter. It mainly applies to the occasions like-as advancing power purchasing to carry out power prepayment and max. load control. This product has characteristics like-of long service duration, high accuracy, good over-load capacity and small volume.

 >> Technical Specification : 

1. Electrical performance:
Class of accuracy: 1.0, 2.0;
Conformed standards: IEC62053 & IEC62055; GB/T17215-2002; GB/T18460.3-2001;
