The Fuji FRN075AR1S-2U is a FRENIC-HVAC series variable frequency drive rated for 75 HP on a 3-phase 230 V supply, in a UL open-type enclosure. It's sized for a 75 HP motor load — think a large HVAC fan, a chiller compressor, or a cooling-tower pump pulling that nameplate.
What the 75 HP rating means for fit
The 75 HP rating at 230 V three-phase tells you the drive's output current capability matches a 75 HP induction motor running on that voltage. In HVAC duty, that typically covers a 60–75 HP fan or pump with variable-torque load.
