Single Phase Two Wire Smart Energy Meter
Type: DDSD1311
This single-phase meter is mainly applicable to the European market and is an important part of the European smart grid. It can achieve external data transmission and interaction through the SML protocol, including two communication channels: INFO and MSB. It supports the import and export of active energy measurement, rate measurement, daily freeze, and PIN display protection functions. This instrument is suitable for residential and commercial users.
