Product Description
Frdm series network multi-functional power meter is an intelligent meter designed for the power monitoring needs of power system, industrial and mining enterprises, public facilities and intelligent buildings. It integrates the measurement of all power parameters (such as single-phase or three-phase current, voltage, active power, reactive power, apparent power, frequency, power factor) and comprehensive power monitoring and assessment management. At the same time, it has a variety of peripheral interface functions for users to choose: with RS485 communication interface, MODBUS-RTU protocol can meet the needs of communication network management; with high brightness LED display interface, through the panel buttons to achieve parameter setting and control, it is very suitable for real-time electric monitoring system. It can directly replace conventional power transmitter and measuring instrument. As an advanced intelligent and digital front-end acquisition component, the power meter is suitable for various control systems and energy management systems.
