● It has forward and reverse active power and combined active energy measurement functions. The combined active power characteristic can be set
● It has time-of-use metering function, which can accumulate and store the total, peak, peak, flat, and off-peak electric energy according to the corresponding time period. It can store the total electric energy and the electric energy of each rate in the last 12 settlement periods.
● Time period rate function: It has two sets of rate time zones and time period tables, which can be automatically converted at the agreed time.
● It has timing, instantaneous, scheduled, hourly and daily freezing functions. The freezing data mode word can be set
● With real-time parameter measurement functions such as voltage, current, power, power factor, grid frequency, etc.
● It has event records such as power outage, event clearing, meter clearing, time calibration, programming, cover opening, etc.
● It has infrared communication and RS485 communication interfaces, and can also customize power line carrier or micro-power wireless communication interfaces to facilitate data exchange with the outside world.
● Electricity bill calculation is completed in the remote electricity sales management system. The electric energy meter can receive the shutdown, permission closing, and ESAM data reading instructions issued by the remote electricity sales management system through virtual media such as RS485, power line carrier, or micro-power wireless. Requires strict password verification and security certification
● Using fully automatic software calibration technology, the calibration is simple, fast and highly accurate.
● It adopts the integrated design of cover and cover plate, which is novel in shape, beautiful and practical.
