Electricity meter,Electricity meter parts,electricity meter kwh General DDS160E single-phase electronic static watt-hour meter is serves as a remote unit in the AMR(Automatic Meter Reading)System, which adopts advanced microelectronics and PLC(Power Line Communication) technology. It can measure active energy of single-phase AC@50Hz. Receiving and transmitting data over the power lines to a central unit-Concentrator, The performance is comfort to IEC 61036:1996 standard. Key Featuresl Measuring AC single-phase bi-directional active energy in wide measurement range, low power consumption and high reliability. l 8 digits 0.01kWh LCD Display. l LED indicator light during power off. l Soft Spread Spectrum Technology is chosen to guarantee the accuracy and reliability of transmitted data over the full distance of the power line. l Automatic relay between meters. l Remote disconnection and reconnection controlled (with the switch accessory). l Power theft detection. l Small physical dimensions. Simple and fast installation. Working PrincipleAs shown in Figure 1, an energy metering IC is adopted (the area inside the broken line). Input Sensor sampling load current and line voltage signal and input to the energy metering IC, which includes a multiplier and a V/F converter. Then output energy pulse signal to IC group for energy consumption counts, LCD display and testing output. The data is transmitted over the power line. The status of the switch is detected by the IC group to realize the remote power disconnection and reconnection.
