DDS-1Y Type Septuple Anti-Tamper Electronic Energy Meter, It has
septuple anti-tamper function which the common anti-tamper energy
meter doesn’t have.
I.Technical Target:a. Working temperature: -20℃~70℃
b. Working Current: 10(40)A
c. Working Frequency: 50Hz
d. Constant: 1600imp/kWh
II. Function
a. RC power supply, anti-tamper in the magnetic field
b. Anti-tamper when the current is unbalanced (If the differences
between two element current is greater than 12.5%, it has tamper
display)
c. Anti-tamper when the meter wires connect reversed
d. It can measure the energy without Neutral wire
e. It can measure the energy without Neutral wire(Anti-tamper when
connect the diode)
f. It can measure the energy without Neutral wire(Anti-tamper when
connect the resistor)
g. It can measure the energy without Neutral wire(Anti-tamper when
connect the capacitor)
III. Features
a. Under tamper status, it has LED display(Alarm sign)
b. When there is 12.5% tamper, it has LED display(Left LED)
c. Reverse tamper, LCD display (Black converse triangle)
d. It also can work normally without voltage, only 1A current exist
IV. Other Features
a. It can roll display active energy one week after cutting off the
power, while one week later, it can not display any
information.When turn on the energy supply, it can display again.
b. When turn on the energy meter, the ID and energy can roll
display
