DTSF669/DSSF6699 Three-phase Electronic & Multi-rate Electric Energy Meter (wireless and carrier wave meter reading function is optional
General Information
DTSF669/DSSF669 three-phase electronic multi-rate active electric energy meter adopts electric energy metering chip with good performance to measure three-phase and four-wire active electric energy in 50Hz/60Hz AC circuit, and can accurately meter without any one phase or two phases, and accurately meter negative connection of each incoming and outgoing wire. In addition to metering the electric energy, the electric energy meter can also measure voltage, current, maximal demand, average power factor, load curve and other parameters. It can set 4 kinds of rates, 12 time areas and 12 time periods. It is particularly designed with power theft detection circuit to make meter can detect reliably and record negative phase of current, short circuit of transformer, load grounding and other power theft events, and the meter can be read and set conveniently with infrared light interface. And part of its performance conforms to requirements of standard IEC62052-11, IEC62053-21 and IEC62054-21.
