DDS7999 Single-phase Electronic Watt-hour Smart KWH Meter

PRODUCT BRIEF INTRODUCTION

Single Phase Two Wire Kwh Watt-hour Meter adopts advanced ultra-low power consumptive solid-state integrated circuit technology and SMT technology. It is used to measure alternating current single phase active power with frequency of 50Hz.The performance index confirms to the technological requirements for the single phase static energy meter according to IEC62053-21:2003 "Part 21 of Special Requirements for AC Measuring Equipments: Static Active Energy Meter(Class1 and Class2)" and "IEC 62052-11-2003".
 
FUNCTION FEATURES
  • The meter features in steady accuracy as any frequency, temperature, voltage and upper harmonic is non-influential to it. It is much more reliable than mechanical meters. There is no need of calibration after the meter is delivered out of the factory, which save the work for the power institutions.
  • It has bi-directional measuring function, which is able to measure positive and negative active energy accurately and the negative energy is added to positive energy.
  • The energy data can be stored eternally even without back-up battery.
  • With passive pulse output interface by optical coupler isolation.
  • The meter features in wide load, excellent accuracy, high reliability, strong sensibility ,flat error line, low
  • power consumption, small size, light weight,energy saving and material saving.The main parameter values are easily read with LCD display.
  • Reverse Tamper Light alarms, when the energy reverses.
  • When there is no external power source, the meter will display Consumed Energy and Maximum
  • Demand with battery back-up.
