The STE38-M is a high-performance STS-compliant prepaid three-phase electricity meter, specifically designed to address dual-power supply management needs in residential, commercial, and industrial scenarios. Its standout dual-source metering capability enables automatic switching between grid power and generator power, with independent measurement and separate billing for each source—eliminating the hassle of manual tracking for areas with unstable grid supply or reliance on backup generators. Additionally, the meter can automatically decrypt recharge codes from different sources and credit funds to corresponding separate balances, ensuring flexible and transparent payment management.
Equipped with international high-end metering chips, the meter achieves Class 1.0 measurement accuracy, reliably monitoring three-phase voltage, current, active/reactive power, four-quadrant energy, and neutral current. The integrated keypad allows users to input recharge TOKENs and query critical data (residual credit, total purchased credit, total consumption) via short codes, while the clear LCD display and LED indicators ensure intuitive operation. For centralized management, an optional RF communication module supports remote reading, real-time consumption monitoring, and remote on/off control, significantly enhancing operational efficiency for utilities and facility managers.
Built with a thickened flame-retardant shell and IP54 dustproof/waterproof rating, the meter delivers exceptional durability and safety in harsh environments. It boasts an 8-year battery life for long-term reliable operation, paired with comprehensive protection features including tamper detection, cover opening detection, low-voltage operation adaptability, and credit alarming. Fully compatible with the StronPay vending system and third-party platforms (M-PESA, Alipay, MTN, Airtel) via APIs, it supports multiple recharge channels (on-site, mobile top-up, door-to-door service) and robust data management. Ideal for industrial parks, commercial complexes, factories, apartments, and supermarkets, this meter serves as a trusted solution for accurate energy measurement, revenue protection, and intelligent consumer management.
