IC card single-phase electricity meter (card insertion type)

DDSY1831 type

Single phase electronic prepaid energy meter (card type)

● Product Overview

The DDSY1831 single-phase electronic prepaid energy meter adopts an advanced microcontroller processing system for data acquisition, processing, and storage. It has good resistance to electromagnetic interference, low power consumption, and long service life. Its biggest feature is to pay before using electricity, completely solving the problem of electricity bill arrears. It is widely used in residential areas, schools, shopping malls, coal mines, underground garages, and new rural construction. All technical indicators comply with GB/T17215.321-2008 and GB/T18460.3-2001 standards.

● Technical indicators

● Functions and features

★ The five digit digital tube displays internal parameters of the electricity meter, such as remaining power, total electricity consumption, and meter number, in a cyclic manner.
★ Prepaid function: The electricity meter adopts the function of buying electricity first, using electricity later, and automatically cutting off power when the electricity is used up.

★ Overload control function: When the load exceeds the internal set value of the meter, the meter will automatically cut off power; When it is less than the set value, it will automatically restore power in about 5 minutes.

★ Power outage alarm function: When the remaining power of the meter reaches the set value, the meter will automatically power off, reminding the user to purchase electricity. After inserting the user card, the meter will automatically power on.
★ One meter, one card, with the function of writing back meter parameters when inserting the card. The design is rigorous and will not cause electricity disputes.
The electricity meter adopts encryption cards and DES dynamic encryption algorithm, ensuring the security and reliability of system data.
The electric meter adopts a magnetic holding relay as the on/off switch, which has strong overload capacity, sensitive and reliable action.
★ The electric meter has high accuracy, strong overload capacity, stable performance, and low self power consumption.
