This is the HVAC-dedicated variant of the FRENIC family, tuned for fan and pump load profiles with built-in PID and energy-saving logic. Rated for 150 HP at 460 VAC three-phase input, the drive handles the constant-torque and variable-torque demands typical of HVAC centrifugal loads — fans, pumps, and compressors in commercial or industrial air-handling systems. Because the FRENIC-HVAC line is current, the FRN150AR1S-4U is sourced through standard Fuji distribution channels. The UL open-type enclosure means it is intended for integration into a customer panel, not as a standalone NEMA-rated unit — factor in the panel space and cooling when specifying. The 150 HP / 460 V rating sets the motor frame size and branch-circuit protection requirements. On a 460 V system, full-load amps for a 150 HP induction motor typically fall around 180–200 A; the drive's input/output current rating must match or exceed that figure. The UL open-type designation means the drive ships without an enclosure — it relies on the panel builder to provide the ambient temperature control and IP rating the installation requires. As an HVAC-specific drive, the FRN150AR1S-4U includes pre-loaded V/f patterns for variable-torque loads, plus a fire-mode override input for smoke-purge sequences. These are not generic VFD features — they save programming time on a chiller or cooling tower retrofit.","metaTitle":"Fuji FRN150AR1S-4U FRENIC-HVAC Drive, 150 HP 460 V 3-Phase","metaDescription":"Fuji FRN150AR1S-4U FRENIC-HVAC drive, 150 HP, 460 V, 3-phase, UL open type.
