STRON STE38-A STS Three-Phase Prepaid Keypad Smart Electricity Meter: Precision & Intelligence for Commercial/Industrial Energy Management

Core Features & Selling Points

• 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 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.

• 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.

• 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.

• Meets STS standards and strict electromagnetic compatibility (EMC) requirements (8kV impulse voltage, 16kV electrostatic discharge), ensuring stable performance in complex electrical environments.
• 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.
