DINGSHUO Single-Phase 1P/2P/4P DIN Rail Smart KWh Meter with RS485 Remote Control

DINGSHUO Three-Phase 4P/7P DIN Rail Multi-Function Energy Meter with Modbus Communication

🔹 Overview 产品概述

The DINGSHUO DDSU (Single-Phase) / DTSU (Three-Phase) series is a compact DIN-rail mounted smart energy meter designed for accurate electricity metering in residential, rental, commercial, factory and construction site applications. It features RS485 communication with dual-protocol support (Modbus-RTU & DL/T645-2007), enabling remote meter reading and control. Available in multiple module sizes (1P/2P/4P/7P) to fit different distribution box requirements.

🔹 Key Features 核心特性

DIN Rail Mount: Standard 35mm DIN rail design, easy installation and removal inside distribution boxes.
Dual-Protocol Communication: Built-in RS485 port supporting both Modbus-RTU and DL/T645-2007 protocols for seamless integration with smart energy systems.
Rolling LCD Display: Segment-code LCD screen with 5-second cyclic display for 8 key parameters (total/resetable energy, voltage, current, power, frequency, meter IDs).
Remote Control & Metering: Supports remote data reading, multi-rate (TOU) metering, and optional remote on/off switching (pull-in/out) via the built-in relay.
High Accuracy & Low Power Consumption: Class 1/Class B accuracy for active energy metering, with ultra-low power consumption to reduce operational costs.
Durable & Safe Construction: Flame-retardant housing and high-quality copper terminals, with explosion-proof LCD design for long-term reliability.
