Product Information
Extended Description
3AUA0000039665 ABB: The compact ACS320 will save energy throughout your pump and fan HVAC applications. From booster pumps, exhaust and condenser fans to supply and return fans, the drive=E2=80=99s built-in HVAC features such as embedded BACnet (MS/TP) ensure easy and complete integration into building management systems.
Feature → Business Impact → Application: The ACS320-03U-23A1-4 is a compact HVAC microdrive that enables precise motor control for pumps and fans while occupying minimal cabinet space, reducing installation complexity and enabling faster commissioning on new or retrofit projects. This directly translates to lower site labor costs and a smaller footprint in equipment rooms, making it ideal for space-constrained HVAC OEM installations and retrofits. Feature → Business Impact → Application: Built-in BACnet MS/TP communication streamlines building automation integration, allowing centralized monitoring, fault detection, and faster troubleshooting across multiple units. In practice, booster pumps, exhaust and condenser fans, and supply/return fans can be controlled from a single BMS, cutting wiring and integration risk. Feature → Business Impact → Application: Energy-efficient control algorithms and variable speed operation deliver measurable reductions in running costs and peak demand, extending motor life and lowering total cost of ownership. This is especially valuable for large-scale hospital, data center, or commercial building projects with continuous fan duty cycles. Feature → Business Impact → Application: 460 V 3-phase input with a 15 HP rating and 30.9 A current profile provides robust start-up torque and reliable performance for medium-size HVAC pumps and fans, increasing system reliability and reducing nuisance trips in variable-load scenarios. Feature → Business Impact → Application: Installer-friendly mounting and standard ABB interfaces streamline procurement, spare parts availability, and service support, ensuring compatibility with existing ABB drive ecosystems and simplifying ongoing maintenance across multiple facilities.
