DTZY2397 Three Phase Prepaid Energy Meter 220V 5-60A with LoRaWAN Communication and Class B Accuracy
The DTZY2397 Three Phase Intelligent Prepaid Energy Meter is a fully digital smart meter featuring SOC high-integration chip technology. This advanced meter provides comprehensive active energy measurement along with online power display, intelligent anti-theft protection, overload control, and remote centralized meter reading capabilities. Data transmission occurs via LoRaWAN/CAT1/Bluetooth wireless networks to corresponding platforms, offering high precision, low power consumption, and excellent stability for three-phase AC power measurement applications in urban, rural, and industrial settings.
- Bidirectional active energy metering with separate accumulation for peak, flat, valley, and total energy periods
- 12-month historical data storage and display of electricity consumption
- Real-time measurement of voltage, current, power, power factor, and frequency parameters
- Advanced overload protection and remote power control functionality
- Dual rate programming with flexible time period settings (minimum 15-minute intervals)
- Comprehensive event recording for zero clearing, programming, timing, and power status changes
