Description
The ABB ACH180-04S-09A8-2 is a purpose-built variable frequency drive (VFD) engineered for HVAC applications including fans, pumps, and compressors. Rated at 208VAC three-phase input with 7.5 RO (rated output) amps, this drive delivers precise motor speed control to optimize energy consumption and extend equipment life in commercial and light-industrial HVAC systems.
The ACH180 series is ABB’s dedicated HVAC drive platform, combining a compact footprint with application-specific features that simplify installation and commissioning. Built-in HVAC-specific functions — including pre-programmed application macros for supply fans, return fans, exhaust fans, and pumps — reduce setup time and help technicians get systems running quickly.
