| DDS523 Single-phase KWH Meter |
|
| Application
|
| Made with advanced technique by adopting large-scale integrated circuit and highly reliable stepping motors etc.,Type DDS523 single-phase electronic watt-hour meters are the newest power counting products in our country to measure single -phase AD active energy with the rated voltage of 220V and and the rated frequency of 50Hz.This kind of products can precisely measure active energy both in positive and negative directions.It can add up the results in a same direction It has the function of anti-stealing electricity.In order to monitor and control active energy easily, it adopts testing signals with light-coupled output and light diodes to indicate the used power capacity.Its technical properties are comformed to the National Standard GB/T17215-98 Grade I and Grade II Static AD Active Meters and the IEC Standard. |
| Working Principles |
| At using the meters, customers can get signal samples through enlargement, multiplication, integral, V/F exchange and divided frequent power on the divided current and divided voltage meters to drive stepping motors and counters add up energy degrees. |
