The ABB ACH580-01-034A-4 is a 3-phase, 480 VAC variable frequency drive (VFD) rated for 34 Amps continuous output (25 HP Normal Duty / 15–20 HP Heavy Duty) from ABB’s dedicated ACH580 HVAC drive series. Housed in a compact R3 frame wall-mountable enclosure (UL Type 1 / IP21), this drive provides precise motor speed control, energy efficiency, and reliable performance across HVAC air handling fans, pumps, and compressors. Equipped with an intuitive Hand-Off-Auto (HOA) assistant control panel, integrated swing choke for harmonic reduction, Safe Torque Off (STO), and native building automation protocols (BACnet MS/TP, Modbus RTU, N2), the ACH580-01-034A-4 simplifies installation and optimizes building control automation.
