Single-phase Electronic Carrier Wave Energy Meter
Detailed Product Description
Brief Introduction
DDS1249 Model Single-phase Electronic Carrier Wave Energy Mete ris 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.
Function and 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;
(4Carrier 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.
