The DTSF666/DSSF666 three-phase electronic multi rate energy meter (hereinafter referred to as the energy meter) is a modern and advanced energy metering product designed and manufactured according to the electricity management needs of three-phase industrial users. It is mainly used in three-phase power grids with a reference frequency of 50Hz (or 60Hz) for time-sharing energy metering and power quality monitoring of three-phase residential users and small and medium-sized industrial and commercial users.
Accurately measure positive and negative active energy, and accumulate negative active energy separately; Equipped with time-sharing metering function, it can accumulate and store total, peak, off peak, flat, and valley active energy according to corresponding time periods. Positive active energy can store data for up to 12 settlement cycles
Accurately measure the maximum demand for total, peak, flat, and valley active power, and store it for 12 months
● Equipped with 2 sets of time zone tables, 8 daily time period tables, and 4 rates
