Double Circuit Single Phase Electric Meter Anti-Tamper KWH Meter
with CT & PT
DDS155 single phase smart anti-tamper electric meter(double circuit
with CT) 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
1. Product's Type—Register (5+1), LCD (5+1 or 6+2), LED (5+1).
2. Electric Power Measurement-- Positive active power, reverse
active power and power in A, B, C phase which can be measured.
3. Intelligent Design—Imported single-chip which controlled by
microcomputer, full digital metering, with advantages of high
accuracy, good linearity, wide range, low consumption and prevent
from electricity stolen.
4. Reliable Design-- Perfect power source and electromagnetism
compatible design, which are suitable to the strong
electromagnetism disturbance and big occasion of power source
5. Cover for Meter-- Fully sealed dustproof and waterproof design,
material of cover has excellent flame retardant and anti-corrosion,
6. On-Off Manner—Build in or external switch can be optional.
7. Communication Mode-- Infrared, RS485 interface or carrier
communication module (Optional).
8. Our products adopt SOC singlechip V9821, enhanced 8052MCU Core,
Double circuit electric measurement, AFE, LCD driver, Flash,
accurate measurement and active power display.
9. Can work at phase(major circuit)or neutral(minor
circuit)measurement. The major and minor circuit can switch.
(threshold value is 12.5%, and the current power is more than 40W).
10. Indicate the current work, power reversed, and anti-tamper.
11. It adopts the lower power display when power off, and display
the current accumulative electricity volume.
12. Anti-tamper function.
