The ECBD005 panel-mounted digital multifunction power meter is designed for intelligent power monitoring and energy metering in power systems, industrial facilities, public infrastructure, and smart buildings.
It can accurately measure key electrical parameters in three-phase power networks, including voltage, current, active power, reactive power, apparent power, frequency, and power factor. The meter also supports RS485 communication and energy pulse output.
With its high cost-performance ratio, the meter can replace conventional indicating instruments, energy meters, and auxiliary devices. As an intelligent digital data acquisition device, it is widely used in SCADA systems, energy management systems, substation automation, distribution network automation, industrial automation, smart buildings, and intelligent switchgear systems.
The meter features easy installation, simple wiring, and convenient maintenance. It supports on-site programmable parameter configuration and can be easily integrated with PLCs and industrial control computers through standard communication software.
• Complies with GB/T 22264 standard.
• Supports both MODBUS and DL/T 645-2007 communication protocols with automatic adaptation.
• The current terminals use stud-type connections to prevent loosening, reducing the risk of overheating and damage caused by poor contact.
