Single-Phase Electronic Meter

1. Summary: DDS3699 series single-phase electronic energy meter is a new generation energy measuring instruments, which adopt special integrated circuit and SMT technology. It is used for the measurement of Single-phase 220V, rated frequency 50Hz or 60Hz active energy in AC grid and can directly replace the induction type single phase watt-hour meter. With low power consumption, high accuracy and strong overload, good electromagnetic compatibility, and long life etc. Features. The technology meets GB/T17215-2002, JJG596-1999, and GB/T17442-2000 standard. 2.
