DDS450 Three Phase Static Meter

DTS450/DSS450 three-phase static active watt-hour meter is designed for measuring active energy by connecting to industrial power supply system, which has firm structure, good appearance and wide practicability. It has high reliability for the adoption of large-scale integrating and SMT technology . We can design the meter with different functions according to user requirement, so it can be wildly utilized in transmission & distribution system and Automatic meter reading system. Basic functions Accumulative bi-directional active energy measurement; One register displays energy value; LED operation indicator; LED indicator for power failure;(for 4 wire meter) Passive pulse output with optical coupling isolation; Optional functions RS-485 and infrared interface; Store total energy of each last 12 months; Active total energy frozen by broadcasting frozen command; Transformer connected; LCD displays energy value.
