Product Description
DTS450J/ DSS450J type three-phase electronic active watt-hour meter (also called watt-hour meter with LCD and RS485 interface) is designed a ND dev eloped for electric power department or user to monitor the power grid qual ity, wi th high accuracy and reliability. The watthour meter adopts the advanced in ternat ional largescale integrated circuit of ultra-low power consumption and SMT process. It accurately measures the active energy of three-phase power grid wit h the re ference ratio of 50Hz. It is designed according to the national standard of GB/T172152002 Alternating Current Static Watt-hour Meters for Active Energy (Classes 1 and 2) and its communication protocol has conformed to DL/T6451997 Multi-function Watt-hour Meter Communication Protocol.

Main functions.
1. Energy measurement
It can measure the forward and reverse electric quantity, display the measurement and accu mulati on of re verse e nergy and forward energy, also can indicate the reverse energy amount. Meanwhile, it can prevent the electricity being theft by reversing the current.
2. Detection interface
There is a detection terminal of photoelectric isolation and pulse output, for checking the meter.
3. Communication interface
There is a RS485 communication interface, convenience for the centralized meter reading syste m.
4. Protection measures
The product internal design has the protection circuit of resisting the lightning strike and high-frequency electromagnetic interference.
5. Wide range of working voltage
In the state of working at 1.5Un over voltage, three luminotrons, representing phase A, phase Band phase C respectively, indicates whether the phase failure happens, if any phase is fail ure, the co rresponding indicator lamp goes out.
