DDZY2397 LoRaWAN Wireless Smart Energy Meter 220V 5-60A Class B Single-Phase Electricity Meter
The DDZY2397 single-phase smart energy meter is a fully digital intelligent electricity meter that combines advanced metering with wireless connectivity. Utilizing SOC high-integration chip technology, this meter provides comprehensive energy management capabilities including active energy measurement, online power display, anti-tampering protection, overload control, and remote centralized meter reading. Data transmission occurs via LoRaWAN/CAT1/Bluetooth wireless networks to corresponding platforms, offering high precision, low power consumption, and excellent stability for urban, rural, and industrial single-phase AC power measurement applications.
- Measures positive and negative active electric energy
- Accumulates and stores energy data for peak, flat, valley periods and total consumption
- Stores and displays various electric quantities from the last 12 months
- Measures and displays voltage, current, power, power factor, and frequency
- Two programmable rate sets (tip, peak, flat, valley)
- Automatic rate switching at preset time points
- Minimum 15-minute interval between periods with cross-midnight capability
- Remote power disconnect/connect via RS485 communication
- Comprehensive event recording for programming, timing, and power events

The electricity meter should be installed indoors whenever possible. For outdoor installations, use special instrument box protection. The mounting base plate must be fixed to walls with strong fire resistance and minimal vibration. Avoid locations with corrosive gases, dust, or salt spray in the surrounding air.
Wiring must be conducted strictly according to the diagram in the meter's tail cover. Use copper wire for terminal connections and ensure terminal screws are properly tightened to prevent overheating and meter damage.
18-month free repair or replacement warranty from delivery date when installation and operation specifications are followed. Comprehensive "three guarantees" service throughout the product lifecycle including technical documentation, wiring diagrams, maintenance training, and regular software updates with free upgrades. Service response within 12 hours of request.
