DTZY666- □ Three phase remote cost control intelligent energy meter (module remote switch internal/external)

● 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

● Time slot rate function: It has two sets of rate time zones, time slot tables, and 254 public holidays, which can be automatically converted at the agreed time

● 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, RS485, GPRS (CDMA, low-power wireless or carrier communication port module optional), convenient for exchanging data with the outside world

The electricity bill calculation is completed in the remote electricity sales management system, and the electric energy meter can receive the instructions for opening, closing, and ESAM data reading issued by the remote electricity sales management system through RS485, GPRS (CDMA, low-power wireless or carrier module optional) virtual media. The instructions need to pass strict password verification and security authentication

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

● It has a load curve recording function, which can scroll record the selected six types of data content at user set time intervals. The interval time can be set arbitrarily from 1 minute to 60 minutes

● It has the function of recording magnetic field interference events
