Supplier's note

  1. Three Technical Breakthroughs:

    • LoRa Integration: Enables 2x longer communication range than traditional RS485, ideal for rural or large industrial sites.
    • High-Precision Impulse Output: The Pro model’s 8000imp/kWh allows 8x finer energy granularity for precise billing.
    • Extreme Temperature Tolerance: Withstands -25℃ to 70℃, outperforming industry-standard -10℃ to 60℃.

  2. Optimal Version Selection:

    • Residential/Small Businesses: Base Model suffices for basic metering needs with RS485 connectivity.
    • Medium-Sized Facilities: Advanced Model adds LoRa for remote monitoring, reducing on-site visits.
    • Industrial/Utilities: Pro Model’s CL0.2S accuracy and infrared interface meet regulatory demands for high-stakes energy auditing.

*CL0.2S: ±0.2% accuracy at 5% load. **8000imp/kWh enables sub-metering for granular energy analysis.
