Network power meterIt integrates power parameter measurement and energy metering, providing communication interfaces to connect with computer monitoring systems. The LCD network power instrument supports RS485 interface MODBUS communication protocol or multiple protocols, forming a network communication structure to achieve automated management of electrical equipment. Network power meters are widely used in medium and low voltage power distribution automation systems, industrial automation systems, intelligent switchgear, building automation systems, load control systems, energy management systems, factory power assessment management, etc.
