DDS5588 single-phase electronic energy meter according to GB / T17215, 321-2008 (IDTIEC1036; 1996) standards for the production of rated frequency 50HZ, rated voltage 220V single-phase AC active energy meter. The product uses a dedicated large-scale measurement of electrical energy and SMT technology to ensure that the measurement accuracy and reliability, for the specifications
The power consumed by the user, through the divider, the flow of the sampling signal to the amplifier and multiplier circuit, the product signal through the integration and VIF conversion, the logic frequency circuit output, drive stepper Or drive the LED display to measure power.
Users should be based on the maximum actual use of power, a reasonable choice of the above specifications, in order to correctly record the electricity consumption, selection of specifications is too large or too small, will result in accounting or fever, etc. are not allowed to burn.
Watt-hour meter in the factory before passing inspection, and sealed with seals, you can install.
The meter should be installed indoors. The bottom plate of the installation table should be fixed on the solid and fireproof wall. It is recommended that the installation height is 1.8m, the standard working temperature is -20degrees to +45degrees, the limit working temperature is -30degrees +55 degrees, There should be no corrosive gas in the air.
Stop after the data is not lost, the use of stepper motor counter.
