ABB ACH580 HVAC & ACQ580 Water/Wastewater Frequency Inverters
The ABB ACH580 and ACQ580 Drive Series (featured model: ACH580-01-045A-4 22 kW & ACQ580-01-045A-4 22 kW) represent ABB's industry-dedicated variable frequency drive platforms, engineered specifically for building infrastructure, HVAC systems, municipal water supply, and wastewater treatment plants. Featuring **native BACnet MS/TP, Modbus RTU, and N2** building automation protocols, the **ACH580** delivers effortless control over supply fans, return fans, cooling towers, and chillers with override fire mode and resonance frequency elimination. The **ACQ580** incorporates specialized water application algorithms, including multi-pump cascade control, sensorless flow calculation, soft pipe fill to prevent water hammer, and anti-ragging pump cleaning cycles. Covering power ratings from 0.75 kW to 500 kW across 3-phase 208V to 480V mains (R1 to R11 frame sizes), ACH580 and ACQ580 inverters feature integrated **chokes for low harmonics** and **Safe Torque Off (STO SIL3/PL e)**, serving as the direct 1-to-1 modernized replacement for legacy **ABB ACH550** and **ACS550** drives.
