1. Product brief introduction

The DDS8111 type single phase electronic kwh meter adopt exclusive use LSI,the device typifying few periphery component, simple structure , high reliability, low power consumption, long life etc, is suitable for the single-phase AC active electric energy with rated frequency of 50Hz,the performance is in conformity with the technical requirements for single-phase electronic watt-hour meter stipulated in GB/T17215 321 -2008 Class I and 2 Static AC Active Watt-hour Meter standard

2.Function and Feature

Measure active electric energy,do not need calibrate for long-term operationLong service life,accessiblel0 yearsSampling current at the same time between phase line and middle line,use the larger as valid sampling,abstraction -of-electricity prevention one fire one ground thoroughlyAdopt exclusive use LSI and SMT surface fixing technique,having advance technoloy and dimple structureAdopt the latest oversea electric energy special integration circuit,greatly improved dynamic working range of MeterHave good mistake linearity in the range of5%lb-lmax,Adopt high reliability and long life electronic component,so the Meter assume feature of high reliability and long lifeLow self power consumption,mighty overload
