Product overviewThe PFNE6-FH509-110 EXA F NET D6 H is an energy analyzer and Web Data Manager designed for integration in industrial Modbus subnets. Accuracy class 0.5S with single-harmonic measurement up to the 51st order. Compatible only with FCTS series flexible split current transformers (CTs not included). Acts as a network bridge between the RJ45 port and the RS485 port for Modbus communication with other Electrex instruments and for local data storage. Includes PFSU940-01 (Log 8) and PFSU940-05 (Web) upgrades. Perennial battery-backed clock and non-volatile memory ensure data retention. Remote firmware update capability and LCD graphic display for local visualization.
