1 year warranty
The ABB ACS320-03U-23A1-4 is a three-phase variable frequency drive designed specifically for HVAC applications, particularly pumps and fans with variable torque loads. This microdrive operates at 380-480V AC input voltage with a maximum continuous output current of 23.1 A and is rated for 15 HP motor loads. The drive features embedded building management system integration with four built-in communication protocols including BACnet, Modbus RTU, FLN, and N2, eliminating the need for external fieldbus adapters. It includes preprogrammed HVAC application macros for simplified commissioning, an energy optimizer for efficiency tuning, and comprehensive PID control features. The unit is supplied in an IP20/UL Open enclosure configuration (frame size R3) suitable for cabinet or wall mounting, with forced air cooling. The ACS320 series is engineered to reduce energy consumption, minimize maintenance costs, and ensure reliable operation in demanding HVAC environments.
