Main functional features

■ It has the function of measuring positive and negative active power and combined active power, and the characteristic word of combined active power can be set.

■Equipped with time-sharing metering function, it can accumulate and store total, peak, off peak, flat, and valley electrical energy according to corresponding time periods,Can be stored on12The total electricity and electricity at various rates for each settlement cycle.

■ It has two sets of rate time zone and time period tables, which can be automatically converted at the agreed time.

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

■ It has real-time parameter measurement functions such as voltage, current, power, power factor, and grid frequency.

■ It has event records such as power failure, event reset, meter reset, timing, programming, and cover opening.

■ Equipped with infrared communicationRS485Power line carrier communication interface, convenient for exchanging data with the outside world.

■The electricity bill calculation is carried out in real-time in the energy meter and can be done throughCPUSolid state media such as cards and RF cards exchange data with the power sales management system.

■Adopting fully automatic software calibration technology, the calibration is simple, fast, and accurate.
