DTS1531J/DSS1531J type three-phase electronic active watt-hour meter (also called watt-hour meter with LCD and RS485 interface) is designed and developed for electric power department or user to monitor the power grid quality, with high accuracy and reliability. The watt-hour meter adopts the advanced international large-scale integrated circuit of ultra-low power consumption and SMT process. It accurately measures the active energy of three-phase power grid with the reference 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/T 6451997 Multi-function Watt-hour Meter Communication Protocol.
