Product Description：
The Hexcell single-phase STS prepaid energy meter is a high-accuracy active energy metering device designed for modern electricity utilities and end-users. It uses digital media for secure information exchange, enabling users to purchase electricity in advance and settle usage via a 20-digit STS TOKEN. Customers obtain the TOKEN through a power vending system and enter it on the external CIU keypad, instantly loading prepaid credit into the meter for reliable active power metering and prepaid control.
This versatile meter supports seamless switching between prepaid and postpaid modes. Depending on the installation environment, it offers flexible communication options—including LoRa, PLC, 2G/4G, LoRaWAN for uplink to AMI systems, and PLC, LoRa, M-Bus or RS485 for downlink communication with the Customer Interface Unit (CIU). Built for residential communities, apartments, factories, shopping malls, office buildings, hotels and photovoltaic power stations, the Hexcell STS prepaid meter delivers accurate metering, anti-tamper protection, multi-tariff capability and long-term reliability under IEC and STS standards.
Key advantages for utilities and users include:
- Secure STS token-based prepayment that reduces revenue loss
- Easy prepaid/postpaid mode switching
- Multiple remote and local communication choices for AMI/AMR integration
- Wide voltage and current ranges suitable for global markets
- Robust design with IP51/IP54 protection and >10-year lifetime
Ideal for utilities seeking to modernize billing, reduce non-technical losses and enable remote management, the Hexcell single-phase STS prepaid energy meter combines proven STS technology with flexible connectivity to support both traditional and smart-grid deployments.
