Overview

DDSI949 single-phase electronic carrier electric energy meter is a high-tech product designed and manufactured using large-scale application-specific integrated circuits, the latest microelectronics technology and SMT process. The circuit design and component selection are based on the allowable large environmental tolerances. Reliably guarantee the long-term stable operation of the electric energy meter. At the same time, it has the characteristics of long life, high accuracy, high reliability, strong overload capacity, small power consumption, small size, light weight and so on.

This product is used for the measurement of single-phase AC active energy with a rated frequency of 50Hz and a rated voltage of 220V, and has the function of power line carrier communication. As a remote carrier wave meter reading terminal, it can form a remote centralized meter reading system with the carrier wave meter reading concentrator and the main station computer to realize the function of remote transmission of electric energy metering and electric energy data. All performance indicators are in line with the national standard GB/T17215-2002 ( Technical requirements for "Class 1 and Class 2 Static AC Active Watt-hour Meters") and DLT698-1999 ("Technical Conditions of Low-Voltage Power User Centralized Meter Reading System").
