ABB 3AXD50000050476 ACQ580-07-0505A-4 ACQ580 ABB Drive

Description: The ACQ580-07-0505A-4 is a cabinet-built ultra-low harmonic inverter designed for HVAC applications. It has a rated power of 250.0 kW (IEC) or 335 Hp (UL) and provides an output current of 505.0 A at 400 V. The inverter operates within a voltage range of 380–480 V AC and features an IP21 enclosure, offering protection against dust and moisture in indoor environments. Its compact design makes it suitable for space-constrained utility rooms or mechanical rooms. By incorporating ABB's active front end (AFE) technology, the inverter reduces harmonic distortion to less than 3% THDi, eliminating the need for external filters. This ensures stable operation and protects sensitive instruments and equipment in HVAC systems. Additionally, the conformal coating on internal PCBs enhances its resistance to harsh environmental conditions such as humidity and corrosive gases, thereby extending its service life in challenging environments.

Features: The inverter is equipped with intelligent pump-specific functions such as dry-run protection, which automatically stops pump operation when fluid loss is detected, preventing pump damage and ensuring system reliability. The soft pipe fill function allows for gradual pressure build-up, effectively preventing water hammer effects that can damage pipes and cause system failures. The sensorless flow calculation capability eliminates the need for external flow meters, simplifying system configuration and reducing maintenance requirements while accurately controlling and monitoring flow rates. It offers dual hardware interfaces that support multiple communication protocols, including CAN, Modbus RTU, PROFIBUS, Ethernet/IP, and USB, enabling seamless integration with various PLC systems and automation networks. The Drive Composer PC tool further enhances its configurability and diagnostic capabilities, making it easy to clone parameters and monitor inverter performance in real-time. This simplifies system setup, commissioning, and troubleshooting processes. The ECO mode dynamically adjusts motor torque based on actual load conditions during partial load operation, resulting in significant energy savings of 15–25% and reduced operational costs while maintaining efficient system performance. The integrated kWh/CO₂ calculator allows users to track energy consumption and carbon emissions in real-time, helping them evaluate and optimize the energy efficiency and environmental impact of their operations. Safety is a top priority for this inverter, featuring Safe Torque Off (STO) and motor thermistor monitoring functions that ensure SIL3/PLd-certified fail-safe shutdowns in the event of faults or emergencies, effectively protecting personnel and equipment and minimizing potential risks in industrial environments.
