Product Description

 

DEM-7M3D series din rail energy meter is designed for DIN-RAIL mounting, suitable for residential energy metering and smart energy project. The Modbus-RTU and pulse output communication of the 3-phase smart energy meter allows seamless integration with data acquisition systems. Various sub-models are available, and prepaid (IC card) is optional. 19D series can transmit data by wireless (4G/5G, Rolar, etc.). Moreover, extension modules are available in built-in and external two versions.

 

The DEM-7M3D three-phase rail energy meter is an intelligent device for medium and low voltage systems (6-35KV and 0.4KV). The 3 phase power meters integrate data acquisition and control functions, adopt segment code LCD screens, and have functions including three-phase AC power measurement and calculation, Electricity accumulation, and RS485 communication. In addition, the energy meter systems can also be equipped with functions such as multi-rate energy metering, maximum demand metering, and 1 channel relay alarm output. The device also provides a communication interface to connect with the computer monitoring system and supports the RS485 interface MODBUS-RTU or DL/T645-2007 communication protocol.
