The Fuji FRN450F1S-4DY is a FRENIC-ECO pump drive rated for 450 HP on 3-phase 460V input. It's built specifically for pump and fan applications where variable torque loads are the norm — think centrifugal pumps, cooling tower fans, or condenser water loops. The F1-DY firmware variant includes pump-specific features like PID sleep/wake and flow compensation that a standard VFD doesn't carry.
This drive is rated for 450 HP at 460V three-phase. The pump-specific firmware handles the PID loop internally.
Deployment context
This is a panel-mount drive, sized for a dedicated enclosure with adequate cooling. At 450 HP, the heat sink needs clear airflow.
