Application

DTS450J/ DSS450J type three-phase electronic activewatt-hour meter (also called watt-hour meter with LCDand RS485 interface) is designed a nd dev eloped forelectric power department or user to monitor the powergrid qual ity, wi th high accuracy and reliability. The watthour meter adopts the advanced in ternat ional  largescaleintegrated circuit of ultra-low power consumptionand SMT process. It accurately measures the activeenergy of three-phase power grid wit h the re ferenceratio of 50Hz. It is designed according to the nationalstandard of GB/T172152002 Alternating Current StaticWatt-hour Meters for Active Energy (Classes 1 and 2)and its communication protocol has conformed toDL/T6451997 Multi-function Watt-hour Meter 

ommunication Protocol.
