1、 Function Overview
The ELA194I-9K4 three-phase current three digit display intelligent meter is designed according to China's requirements for the operation and monitoring of power equipment. Users can adjust the CT parameters through panel buttons to intuitively display the system's operating current. The three rows of digital tubes simultaneously display the three-phase current value, which is clear and beautiful. It can replace traditional analog pointer meters. The communication adopts RS485 interface and exchanges data with microcomputers. It is a high-performance automation instrument most suitable for modern power supply and distribution systems such as industrial and mining enterprises, civil buildings, and building automation.
