The ABB ACH580-01-02A1-4 is a 3-phase, 480 VAC variable frequency drive (VFD) rated for 2.1 Amps continuous output (0.75 HP to 1 HP) from ABB’s dedicated ACH580 HVAC drive series. Housed in a compact R1 frame wall-mountable enclosure (UL Type 1 / IP21), this drive delivers precise motor speed control, energy savings, and high operational reliability for HVAC air handling fans, small pumps, and industrial blowers. Equipped with an intuitive Hand-Off-Auto (HOA) assistant control panel, an integrated variable swing choke for harmonic mitigation, dual-channel Safe Torque Off (STO), and embedded building automation protocols (BACnet MS/TP, Modbus RTU, JCI N2), the ACH580-01-02A1-4 seamlessly integrates into modern facility automation networks.
