STRON STE38-A STS Three-Phase Prepaid Keypad Smart Electricity Meter: Precision & Intelligence for Commercial/Industrial Energy Management
Introducing the STRON STE38-A—an advanced three-phase keypad-type prepaid electricity meter engineered for three-phase four-wire systems, delivering reliable measurement and intelligent energy management for commercial, industrial, and utility-scale applications. Compliant with global standards and packed with user-centric features, this meter combines precision, durability, and flexibility to optimize power distribution and consumption monitoring.
Core Features & Selling Points
✅ Class-Leading Measurement Precision
Class 1.0 accuracy rating paired with high-end international metering chips, ensuring precise measurement of three-phase voltage, current, active/reactive power, and four-quadrant energy.
Supports neutral current measurement and bidirectional metering, capturing granular energy data with minimal error (≤±2% for normal flow) for fair billing and efficient energy analysis.
Low starting current (30mA) and stable performance across a wide voltage range (70%~120%Un), guaranteeing accuracy even in low-load or fluctuating power conditions.
Compliant with STS standards for secure prepaid management, supporting 20-digit token recharge via multiple convenient methods: on-site recharge points, third-party platforms (M-Pesa, Alipay, MTN, Airtel), and door-to-door mobile vending units.
Integrated keypad + LCD display for intuitive local operation—users can easily enter recharge tokens, check balance, and view consumption data without additional devices.
Multi-tariff flexibility (up to 8 tiers) and credit alarming function, enabling demand-based pricing and helping users avoid unexpected service interruptions.
✅ Optional RF Module for Remote Intelligence
Optional RF communication module unlocks remote capabilities: real-time consumption monitoring, data collection, remote reading, and remote on/off control.
Seamlessly integrates with STRON’s AMI solution and data concentrators (DCU), covering up to 900m radius for centralized energy management in residential areas, industrial parks, and commercial complexes.
✅ Robust Durability & Long-Term Reliability
IP54 protection rating: Dustproof and water-splash resistant, built to withstand harsh operating environments (-25℃~70℃ working temperature, -40℃~85℃ storage temperature).
Thickened flame-retardant shell (Class II insulation) and tamper detection (cover opening + magnetic interference protection): Ensures safety, prevents theft, and maintains data integrity.
8-year long-life battery and replaceable components: Reduces maintenance frequency and long-term operational costs.
✅ User-Friendly Design & Wide Application
Back-mounted hanging hole + fixed triangular positions: Enables quick and easy installation for various scenarios.
Comprehensive event logging: Tracks tamper events, recharge records, and consumption data (with real-time clock timestamping) for audit trails and transparency.
Ideal for industrial parks, commercial complexes, large public facilities, factories, office buildings, supermarkets, and apartment rentals—adapts to both balanced load and diverse energy management needs.
✅ International Compliance & Secure Vending System
Integrates with StronPay vending system (backed by Microsoft SQL Server) for secure data management, report generation, and account control—supports API integration for personalized business needs.
