IC card single-phase electricity meter (tiered pricing type)

DDSY1831 type

Single phase electronic prepaid energy meter (tiered pricing type)

● Product Overview

The DDSY1831 single-phase stepped electricity meter adopts an advanced microcontroller processing system for data acquisition, processing, and storage. It has the characteristics of good resistance to electromagnetic interference, low power consumption, and long service life. Its feature is to pay first and then use electricity. It adopts multiple stepped electricity prices, with different electricity consumption rates, 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:

● Functional features:

1. LCD Chinese display, with clear and intuitive display content.

2. 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.

3. 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, 5

Automatically restore power in about minutes.

4. Power off alarm function: When the remaining power of the meter reaches the set value, the meter automatically shuts off, reminding the user to purchase electricity and plug in

After entering the user card, the electricity meter will automatically power on.

5. Ladder pricing function: According to the requirements of the local electricity management department, a ladder can be set arbitrarily to achieve tiered usage

Charges.

6. Each meter has its own card, and when inserting the card, it can write back the meter parameters. The design is rigorous and will not cause any electricity disputes.
7. The electricity meter adopts encryption cards and DES dynamic encryption algorithm, ensuring the security and reliability of system data.
8. The electric meter adopts a magnetic holding relay as the on/off switch, which has strong overload capacity, sensitive and reliable action.
9. The electric meter has high accuracy, strong overload capacity, stable performance, and low self power consumption.

10. Network meter reading function: With a 485 interface, it can read the electricity consumption of each meter at any time, making it easy for management departments to calculate monthly data

Electricity consumption per kilowatt hour (optional).

11. Control power on/off function: Through the 485 network, the property management department can control the on/off of users' electricity meters without leaving their homes

Electricity. (Optional).
