DDS155 single phase smart anti-tamper electric meter(double circuit with CT and PT) is a kind of fully digitized intelligent energy meter. It adopts the SOC high-density V9821 chip. It has the function of major and minor circuit electric measurement, online power display, smart anti-tamper, outage display. It is high accuracy, low power consumption, and good stability. It can be widely used for the single phase alternating current in city, rural areas or factory enterprises, etc. 

Main function characteristics

(1) Our products adopt SOC single chip V9821, enhanced 8052MCU Core， Double circuit electric measurement, AFE, LCD driver, Flash, accurate measurement and active power display.

(2) Can work at live wire(major circuit)or neutral wire (minor circuit)measurement. The major and minor circuit can switch. (threshold value is 12.5%, and the current power is more than 40W).

(3) Indicate the current work, power reversed, and anti-tamper.

(4) It adopts the lower power display when power off, and display the current accumulative electricity volume.

(5) Anti-tamper function.
