Dual Source Three-phase Electricity Meter automatically switches measurement between Grid and Generator sources

• Dual-Source Prepaid Design: A three-phase prepaid electricity meter that automatically switches measurement between Grid and Generator sources, supporting separate billing and independent balance top-ups via auto-decrypted recharge codes from different sources.
• STS Compliance & High Precision: Adheres to STS standards for multi-phase prepaid management, equipped with metering chips from international high-end brands to ensure Class 1.0 measurement accuracy.
• User-Friendly Operation: Integrated keypad for entering recharge tokens and querying key data (Residual Credit, Total Purchased Credit, Total Consumption) via short codes; featured with an LCD display for clear information reading.
• Remote Functionality Support: Optional RF communication module enables real-time consumption monitoring, data collection, and remote on/off control of the meter.
• Durability & Protection: IP54 rating for dust and water splash resistance; thickened flame-retardant casing ensures safety and stability; 8-year long battery life for reliable operation.
• Comprehensive Functionalities: Includes STS token recharge, event logging, real-time clock, cover opening detection, neutral current measurement, automatic switch-off, tamper detection, low-voltage operation, multi-tariff support (max 8 tariffs), remote reading, and credit alarming.
• Robust Technical Performance: Operates within a wide voltage range (70%~120%Un) and frequency range (50-60Hz); supports basic current (Ib) of 10A and maximum current (Imax) of 100A; excellent electromagnetic compatibility (EMC) with strong resistance to static discharge, RF fields, and transient bursts; wide operating (-25°C~70°C) and storage (-40°C~85°C) temperature ranges.
• Easy Installation: Features fixed triangular positions and hanging hole design on the back for convenient mounting.

Selling Points

1. Convenient Recharge Options: Supports multiple top-up methods, including on-site recharge at nearby points, mobile payment via third-party platforms (e.g., M-PESA, Alipay, MTN, Airtel) with API integration, and door-to-door recharge by mobile vending units—allowing users to top up electricity remotely without leaving home.
2. Powerful Supporting System: Equipped with the StronPay vending system, which offers comprehensive data management (covering meters, prices, customers, etc.), flexible recharge services (by amount/unit), detailed report generation (receipts, monthly summaries, etc.), and secure account management (password modification, sub-account creation). The system uses Microsoft SQL Server for data security and supports API expansion for personalized needs.
3. Wide Application Scope: Suitable for households, apartment rentals, supermarkets, convenience stores, factories, office buildings, industrial parks, commercial complexes, and large-scale public facilities—serving as a core terminal for intelligent power distribution, energy management, and revenue protection for utilities.
4. Smart Ecosystem Compatibility: Integrates with STRON AMI solutions, compatible with electric, water, and gas meters; DCU deployment is optimized for signal coverage (considering building density and elevation), ensuring stable data transmission within 900m radius in residential areas.
5. User-Centric Convenience: Enables users to check electricity information via mobile phones; the vending system generates 20-digit recharge tokens with receipts, simplifying transaction tracking.
6. Reliable Safety & Security: Class II protection, 4kV AC insulation strength, and tamper detection (cover opening/tampering records) prevent revenue loss; flame-retardant materials and EMC compliance ensure long-term safe operation in harsh environments.
