Product details

Integration notes

The FRN900F1S-4DY: This is a panel-mount core drive, not a standalone enclosed unit — it lands on a backplate or sub-panel inside the motor control center. The 900 HP rating means it occupies a large frame size; verify the mounting footprint and gland plate access against the enclosure layout before committing the panel design. The F1-DY pump variant typically includes built-in PID control for pressure or flow regulation, so an external controller may not be needed for closed-loop pump applications.

Frequently asked questions

What is the closest alternative to the FRN900F1S-4DY in the FRENIC-ECO family?

The FRENIC-ECO Pump series includes lower horsepower variants (e.g., FRNxxxF1S-4DY) that share the same pump firmware and form factor. The deciding factor is the motor load: step down to the next available rating if your load is under 900 HP, but verify the output current matches your motor FLA. There is no pin-compatible drop-in; the frame size changes with horsepower.

What compliance documentation does Fuji provide for this drive?

Fuji typically provides a Declaration of Conformity for CE marking, UL listing documentation for the US market, and RoHS/REACH compliance statements on request. Specific cert numbers are not listed in this entry; request them with your RFQ to satisfy your quality documentation gate.
