Descriptions
DDS54 single phase electronic energy meter adopting specialized large scale IC and SMT technology, mechanical drive counter, no data loss after power off, it is one of updated energy meters . The mete is single phase and active with rated voltage 220V, rated frequency 50Hz. It’s capability is completely conform to IEC1036<> and GB/T17215-2002<>
Main functions and characteristic
1.The meter is small in size, light weight, high precision, low consumption, wide load, fix convenient etc.
2. The meter has bi-direction functions, can measure accurately bi-direction power, calculate the energy in one direction, so the meter has the function of anti electricity-stealing.
3. The meter is adopting photoelectric coupler output test signal, LBD indicate power consumption.
4. The mete have the feature of function expand, for example can add prepayment function, power line carrier function, are convenient for automatic management for power supply department.

Work principal
The energy consumed by user is pass through voltage transformer and current transformer, sampled signal , then the signal send to amplify and multiplication circuit and integral and V/F transfer, output signal from detach frequency and power drive circuit, drive the counter to cumulate the energy.
Installation and connection
1.After the meter is test eligibility, sealed, the meter can be installed. The meter should be installed inside room, the soleplate for meter installation should be fix on solid and fire proof wall, the advised height is 1.8 meter, the temperature should be -10℃——+45℃, relative humidity should be not more than 85%, no caustic substance is in the air.
2. Figure dimension: length x width x height = 110mm x 148mm 55mm
3. The meter should be connected according to the diagram on the terminal comer, 1. 2. 3 .4 terminals should be better introduced by bronze line or bonze tie-in, 5(+),6(-) terminal is output for pulse signal, it is a port for error test or pulse signal.
4．Diagram of connection as follow:
Transportation and storage
1. The meter should be avoided to strike violently during transportation and open, and transported and stored according to ZBY03-82184<>.
2. The meter should be kept on original packing , temperature should be 25℃~+70℃，relative humidity should be not more than 85%, no caustic substance is in the air.
3. When the meter is stored on the shelf in the carton , the placed height should be not more than five cartons, after opened, the meter placed height should be not more than ten pieces.
