The Fuji Electric FRN500F1S-4U is a FRENIC-Eco (F1) series variable frequency drive rated 500 HP (650 A rated output current) for 460 VAC three-phase input. The FRENIC-Eco platform is Fuji Electric's energy-saving drive family purpose-built for variable-torque HVAC, pump, and fan applications, with an optimized V/f control algorithm, a built-in PID controller for pressure or flow control, RS-485 Modbus RTU communication, and comprehensive motor and drive protective functions.
This model has been discontinued by Fuji Electric; availability is limited to remaining stock. For new installations, Fuji Electric recommends the FRENIC-MEGA (G2) series, with model FRN0610G2W-4GU as the suggested current-generation replacement.
