Product Description：
Electricity utilities often face challenges with traditional postpaid metering, including delayed payment collection, manual meter reading, limited control over electricity consumption, and difficulty managing different tariff structures. These challenges can increase operational costs and make electricity revenue management more difficult.
The Hexcell DDSY1088/DDS1088 is a single-phase RF card prepaid/postpaid energy meter designed for residential and commercial electricity metering applications. It supports the “pay first, use electricity later” model, allowing utilities to collect electricity payments before energy consumption and helping reduce payment collection risks.
Users can recharge electricity through an RF card, while utilities can also use remote meter reading systems for data collection and management. The meter supports flexible tariff management, including multi-tariff and tiered electricity pricing, making it suitable for different electricity pricing policies.
The meter can communicate with an AMI system through interfaces and communication technologies such as RS485 and LoRa, while additional communication options include IR, PLC, 2G/4G and LoRaWAN. This enables remote energy data collection, meter management and electricity consumption monitoring.
The meter also provides configurable control and monitoring functions, including recharge management, arrears switch-off, automatic switch-off, freezing of electricity consumption data, fault/event recording and automatic meter reading.
The DDSY1088/DDS1088 supports:
- Prepaid and postpaid operating modes
- RF card electricity recharge
- Remote meter reading
- RS485 and LoRa communication with AMI systems
- Multi-tariff and tiered electricity pricing
- Forward/reverse active and reactive energy measurement
- 12-month energy data storage
- Event recording for recharge, switch-on/off, cover opening, power failure, reverse energy, overvoltage and undervoltage
- IEC 62056-21 Mode C / DLMS communication protocol
- IEC 62052-11, IEC 62053-21, IEC 62053-23, IEC 62055-31 and IEC 62055-41 standards
- STS, KEMA and DLMS-related certification information
- More than 10 years' expected service life
