DDSI6789 Carrier
electronic energy meter

DDS16789
Model Single-phase Electronic Carrier Energy Meter is used to measure the
single-phase AC active power at 50Hz or 60Hz. It is a full electronic energy
meter with the function of power wire carrier wave communication. This series
power meter conforms to GB/T 17215.321-2008, GB/T 15284-2002 and DL/T645-1997
standard.

Features:

1.
Measuring function: accurately measure the two-way energy.(The reverse is
measured positively).

2.
Carrier wave communication function: It can upload the meter information (including
electric quantity, parameter, state ect.) and receive the command and carry out
the controlling action ( it can switch on and out, when it is with the relay
device) through the low-voltage power wire carrier wave and the centralized
controller communication in the count. In this way, it realize the function of
centralized meter recording with centralized controller and upper computer.

3.Carrier
wave communication parameter: 4 digits BCD code (the last 4 digits of the meter
number) address. Single-rate procotol reading system. Direct sequence spread
specrum 15 digits, PSK modulation, Central Frequency 120Khz, bandwidth 15kHz;

4.Carrier
wave communicaiton capability: Communication distance 1000m(between every two
knotting points). Function of 4 level relay to expand the communication
distance.

5.Convenient
to install. It can realize the function of centralized recording without any
assisted wire.

6.Control
function (with internal magnetic keeping relay) can be made to order, according
to cutomersrequirement.
