Chint DDSU/DTSU666 Single & Three-Phase DIN Rail Smart Energy Meter with RS485 Modbus Communication, Direct/CT Connected

🔹 产品概述 (Overview)

The Chint DDSU666 (Single-Phase) / DTSU666 (Three-Phase) series is a DIN-rail mounted smart energy meter designed for accurate electricity metering in residential, rental, commercial, factory and construction site applications. It supports both direct connection and current transformer (CT) connection, featuring RS485 Modbus communication for remote monitoring and multi-rate energy management (optional).

🔹 核心特性 (Key Features)

  • DIN Rail Mount: Standard 35mm DIN rail design, easy installation and removal inside distribution boxes.
  • Clear LCD Display: Segment-code LCD screen with 5-second rolling display for energy consumption, voltage, current, power, power factor and frequency.
  • High Accuracy & Low Power Consumption: Class 1/Class B accuracy for active energy metering, with ultra-low power consumption to save energy.
  • Smart Communication: Built-in RS485 port supporting Modbus-RTU and DL/T645-2007 protocols for remote data reading and monitoring.
  • Flexible Specifications: Multiple voltage/current ratings available (220V single-phase / 3×220/380V three-phase; up to 100A direct / 6A CT-connected).
  • Optional Functions: Multi-rate metering, built-in relay for remote on/off control (for select models).

🔹 应用场景 (Applications)

  • Residential homes & rental properties
  • Small commercial buildings, factories and workshops
  • Construction sites, temporary power distribution
  • Energy management systems, solar PV monitoring, smart grid project
