Descriptions
DDS54-J single phase electronic energy meter is equipped with specialized large scale IC and SMT technology, mechanical counter, no data loss after power off, it is one of the most advanced measure meters in domestic market. The rated voltage of the meter is 220V, rated frequency is 50Hz, The meter can measure AC active single phase energy. The capability is conformed to IEC1036<< grade1.0 and 2.0 static AC active energy meter>> and GB/T17215-2002<< grade 1.0 and 2.0 static AC active energy meter>>
Main functions and characteristic
1. The meter is small in volume, light weight, high precision, low power consumption, wide load, fix convenient.
2. The meter has the function of bi-direction measurement, which can measure accurately bi-direction power, and calculated as one direction, with electricity pilfer indication function.
3.The meter is adopting photoelectric coupler output test signal, LBD indicate energy consumption

Work principal
The power consumption of user is sampled through voltage transformer and current transformer, then send to amplify and multiplication circuit, the signal is through integral and V/F transfer, through frequency and power drive circuit output pulse signal, drive the counter to calculate the power consumption
Installation and connection
1. After the meter is check out and seal in factory, the meter can be installed and operated. The meter should be installed in the room, the meter should be fix on solid and fire proof wall, the suggested height should be 1.8 meter, the temperature is -10℃——+45℃, relative humidity is not more than 85%, no caustic substance is in the air.
2. Figure dimension: length x width x height = 100mm x 148mm x 55mm
3. The meter should be connected according to the connection diagram on the terminal cover, 1,2.3,4 terminal is better be introduced by bronze line or bronze tie-in, 5(+),6(-) is output port for pulse signal, there are for error test or interface for pulse signal.

Transportation and storage
1、The meter should be avoid to strike violently during transport and open , and transportation and storage should conform to GB/T15464-1995<>
2. Keep the meter in original package, the temperature should be -25℃~+70℃, and relative humidity should be not more than 85%, no caustic substance is in the air.
3.When the meter place on shelf, the height should be not more than five cartons, and after open the carton, the height of meter placed should be not more than ten pieces.
