ABB (Cary, NC) has introduced the ACH580 4X variable frequency drive (VFD), a new addition to its all-compatible drive portfolio that is built for outdoor installation and extreme environments in the HVACR industry. Certification to UL Type 4X (NEMA 4X and IP66 rating) ensures protection against rain, cold, snow, salt spray and dust as well as corrosion due to caustic chemicals, gasses and damage from the formation of exterior ice, high levels of humidity or UV radiation.

Purpose-built for HVACR, the ACH580 4X drive incorporates features like flying start for seamless control of spinning motors, multi-pump control for enhanced system efficiency, freezestat response, resonance monitoring, and an override capability for fire emergencies. Convenient options include a built-in disconnect switch to streamline installation and eliminate the need for branch circuit fuses (while maintaining a 100 kA SCCR), as well as a sun shield to help maintain optimal performance when exposed to direct sunlight.

Equipped with HVACR-specific software features, the ACH580 4X drive ensures ease of commissioning and use. It features a standard Bluetooth control panel for seamless and secure connectivity, commissioning, and monitoring through ABB apps like Drivetune and Drive Composer. The Bluetooth panel not only enhances convenience but also improves safety by keeping staff out of the arc flash boundary.

It is available in multiple power ratings from 1 to 30 HP in 1-phase 240 V, 3-phase 208-240 V, 3-phase 380- 480 V, and 3-phase 500 - 600 V.
