ABB ACH580-31-039A-4 ultra-low harmonic HVAC wall-mounted drive, an 18.5 kW, 38 A, 400 V three phase AC variable frequency drive designed for fans, pumps, compressors, air handling units and building services motor control.
The ABB ACH580-31-039A-4 (Product ID 3AXD50000047699) is a high-performance AC variable frequency drive (VFD) designed specifically for HVAC applications where energy efficiency, reliable motor control and improved power quality are essential. As part of the advanced ABB ACH580 HVAC drive series, it provides dependable speed control for fans, pumps, compressors and air handling systems.
This ultra-low harmonic wall-mounted drive is engineered to reduce harmonic distortion in electrical networks, helping support cleaner power quality in building services and industrial HVAC installations. Its integrated HVAC functionality, straightforward commissioning tools and robust ABB drive platform make it suitable for modern plant rooms, commercial buildings and facilities management systems.
With a rated output power of 18.5 kW, a rated output current of 38 A and a 400 V three-phase supply, the ACH580-31-039A-4 is ideal for medium-power HVAC motor applications requiring efficient control and reduced harmonic impact.
Variable frequency drives such as the ABB ACH580-31 regulate motor speed by adjusting output voltage and frequency. In HVAC systems, this allows fans, pumps and compressors to operate according to actual demand, helping reduce energy consumption while maintaining comfort and process stability.
The ultra-low harmonic design helps reduce distortion on the electrical supply, making the drive especially useful in buildings and installations where power quality is important. This can help minimise the need for additional harmonic mitigation equipment while supporting reliable HVAC operation.
