Product detail:
DDS Single phase electrical type KWH meter
1. Product Introduction
Being made of special use large-scale integrated circuit and imported high reliable electronic components. The series of products have the functions of electricity-steal protection and accumulated measurement of forward and backward active electric network with 200V voltage and 50Hz frequency.
Before delivery each of the products is subjected strictly to the 200VAC high voltage,70 °C high temperature energization and aging tests , there fore. ourproducts have reliable quality and can be used continuously to meter electrie energy accury for more than 110 years
2. Function and Features.
Measure active electric energy,do not need calibrate for long-term operation;
Adopt lasted electricity dedication integrated circuit including digital multiplier overseas,greatly improved dynamic working range of meter,making 10mutiple actual overload;
Have good mistake linearity in the range of 4%Ib-Imax;
Few periphery componenet,simple structure,low power consumption;
Adopt high reliability and long life electronic component,so the meter assume feature of high reliability and long life.
Way of display:register,LCD,digital tube;
Romote interruption of power supply function.
