DDZY666C - □ single-phase local cost control intelligent energy meter (module CPU card switch internal/external)

● It has the function of measuring positive and negative active power and combined active power, and the characteristic words of combined active power can be set

● It has a time-sharing metering function, which can accumulate and store the total, peak, off peak, flat, and valley electricity energy according to the corresponding time period. It can store the total electricity energy of the previous 12 settlement cycles and the electricity energy of each rate

● Equipped with local cost control function

● 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, 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 communication, RS485 communication interfaces, and customizable power line carrier or low-power wireless communication interfaces for easy data exchange with the outside world

● It has local cost control functions such as decreasing remaining amount, insufficient remaining amount alarm, overdraft, and anti hoarding

The electricity bill calculation is carried out in real-time in the energy meter, and data exchange can be carried out with the electricity sales management system through solid-state media such as CPU cards. The CPU card adopts the SM1 national encryption algorithm

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

● Adopting an integrated design of cover and cover plate, the shape is novel, beautiful and practical
