DT/SZ666 three-phase intelligent electric energy meter (0.2S level, 0.5S level)

● It has the function of measuring positive and negative active power, four quadrant reactive power, and can set the combination of active and reactive power based on this

● It has a time-sharing metering function, which can accumulate and store total, peak, off peak, and valley active and reactive energy according to corresponding time periods

● Equipped with phase separated active energy metering function

Measure the maximum demand in both directions, the maximum demand in different time periods, and their dates and times of occurrence, and store data with time stamps

● It has two sets of rate time zones, time slot tables, and 254 public holidays, which can be automatically converted at agreed upon times

● Measure fundamental and harmonic electrical energy separately

● It has the function of calculating the active power compensation for copper and iron losses in phase and phase separation

● It has real-time parameter measurement functions such as voltage, current, power, power factor, and current demand

● It has functions of timed, instantaneous, agreed, hourly, and daily freezing, and the freezing data mode can be set

● Equipped with infrared communication port and RS485 for convenient data exchange with the outside world

● It has event recording functions such as voltage abnormality, current abnormality, power failure, reset, timing, programming, opening the meter cover, and starting button cover

● Equipped with load curve recording function, it can scroll record the selected six types of data content according to the user's set time interval, and the interval time can be set arbitrarily from 1 minute to 60 minutes

● Equipped with auxiliary power supply

● It has the function of recording magnetic field interference events
