The DDZY2397 single-phase smart energy meter is a fully digital intelligent electricity meter featuring LoRaWAN wireless communication. Utilizing SOC high-integration chip technology, this meter provides active energy metering along with advanced functions including 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. Designed for high precision, low power consumption, and excellent stability, it's suitable for single-phase AC power measurement in urban, rural, and industrial applications.

• Metering of positive and negative active electric energy with separate accumulation for peak, flat, valley periods and total energy
• 12-month historical data storage and display of various electrical quantities
• Real-time measurement of voltage, current, power, power factor, frequency and operating parameters
• Built-in overload protection function for enhanced safety
• Two programmable rate sets (tip, peak, flat, valley) with flexible time period scheduling
• Event recording for zero clearing, programming, timing, power failure, and switching operations
• Remote power control via RS485 communication interface for load circuit management

Terminal functions: 5-6 (reactive pulse output - empty), 7-8 (active pulse output), 9-10 (clock), 11-12 (RS485 communication).

158mm × 112mm × 58mm (L × W × H)

The electricity meter should be installed indoors whenever possible. For outdoor installation, use special instrument box protection. Mount the base plate on a sturdy, fire-resistant wall with minimal vibration. Avoid installation in areas with corrosive gases, excessive dust, or salt spray.

All wiring must strictly follow the diagram provided 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 from poor contact.
