The Fuji FRN025AR1M-5U is a FRENIC-HVAC series variable frequency drive rated for 3-phase 575V input, 25HP output, in a UL/NEMA Type 1 enclosure.
575V three-phase input and 25HP output target the North American 480/575V industrial HVAC segment — think rooftop units, large fan arrays, and pump banks in commercial buildings. The UL/NEMA Type 1 enclosure means it's intended for indoor installation where falling dirt and incidental contact are the only hazards; no hose-down or dust-tight protection. The FRENIC-HVAC series is Fuji's purpose-built line for fan and pump applications, with built-in PID, fire mode override, and sleep/wake functions. If the BOM calls for a general-purpose drive with HVAC-specific firmware, this is the direct match — no parameter rework needed compared to a standard FRENIC-Mini or FRENIC-Ace.
