Advantages of IC card prepaid energy meters
Shandong Keda Zhongtian Electronics Co., Ltd. specializes in the production and sales of prepaid energy meters, DF multi-user smart meters, multi-user energy meters, electronic meters, apartment ** meters, high-current centralized meters, and multi-user smart meters . The IC card pre-paid energy meter is a kind of pre-paid energy meter. The following will be explained by Shandong Science and Technology University Zhongtian Xiaobian to its advantages in practical applications.
All electronic design, built-in imported special chip, accuracy is not affected by frequency, temperature, voltage and high harmonic
Adopt SMT technology, optimized circuit design, no need to adjust the circuit after the whole machine leaves the factory.
Low power consumption
Low power consumption design is adopted to reduce grid line loss.
The IC card transmits data to realize data readback, including: reading back the total power, remaining power, accumulated power purchase in the table, total number of power purchases and other information.
Store table constants, initial values, user address, name and other information.
Overload alarm, power failure, remaining power alarm, remind users to purchase power in time.
Technical parameters: Long-life base table is used to extend the service life
Accuracy level is 2
Current range: (1.5 (6) A, 10 (40A), 15 (60A), 20 (80A)
