Zhongyi's Single-Phase STS Prepaid Meter

Key Features of the DDSZY06 STS Prepaid Meter

1. Prepaid Functionality

The meter operates on a prepaid model, allowing users to purchase electricity credits via 20-digit encrypted tokens (TOKEN). This "pay-as-you-use" approach empowers consumers to manage their energy budgets effectively while minimizing the risk of unpaid bills for utility providers.

2. High-Accuracy Measurement

Equipped with a high-precision metering chip, the DDSZY06 ensures Class 1 accuracy in measuring active energy. It supports bidirectional energy tracking, including total positive/negative active energy and tiered tariff calculations, making it suitable for residential and commercial applications.

3. Robust Data Security

Leveraging advanced encryption algorithms like TDEA, the meter generates secure tokens with unique serial numbers and timestamps. This prevents token replay attacks and ensures tamper-proof transactions, aligning with the IEC62055-31 STS standard.

4. Intuitive LCD Display

A high-definition LCD screen provides real-time information, including:

◦ Remaining credit balance

◦ Cumulative energy consumption

◦ Voltage, current, and power factor

◦ Historical data and event logs

Users can easily monitor their usage and receive alerts for low credit or abnormal events.

5. Anti-Tampering Mechanisms

The meter detects and records unauthorized access, magnetic interference, and cover-opening events. With an IP54 protection rating, it operates reliably in diverse environments, from humid climates to dusty installations.

6. Flexible Communication Options

Support for infrared and RS485 interfaces enables seamless integration with energy management systems. The meter also complies with the DLMS/COSEM protocol (IEC62056-21), ensuring interoperability with global utility infrastructures.
