Applications & Use Cases
The ABB ACS800-704LC-2150-7 drive supply unit is designed for deployment in the most power-intensive industrial automation systems where multiple large motors must be controlled from a common DC bus. Its primary applications span across several heavy industries:
Multi-Drive Industrial Systems
Large manufacturing complexes utilize common DC bus architectures where a single drive supply unit feeds multiple inverter modules. This approach reduces line-side harmonics, improves power factor, and enables energy sharing between motors in regenerative applications. The ACS800-704LC-2150-7 provides the central power conversion function for these sophisticated multi-drive configurations.
Marine and Offshore Power Systems
Electric propulsion systems, dynamic positioning vessels, and offshore drilling rigs require massive power conversion capacity to control propulsion motors, thrusters, and drilling equipment. The 1796A input capacity and robust Finnish construction make this drive supply unit an excellent choice for marine electric power systems where reliability is literally mission-critical.
Pulp, Paper and Board Mills
Paper machines, stock preparation systems, and finishing departments in pulp and paper mills utilize large multi-drive systems with dozens of coordinated motors. The ACS800 common DC bus architecture simplifies system design, reduces energy consumption through regenerative braking, and provides the precise speed control necessary for high-quality paper production.
Metal Processing and Mining
Rolling mills, mine hoists, conveyor systems, and crushers in the metals and mining industries demand high-power variable speed drives that can operate reliably in harsh environments with heavy dust, vibration, and temperature extremes. The IP00 construction allows custom enclosure designs tailored to these challenging conditions.
Oil, Gas and Petrochemical
Refineries, petrochemical plants, and pipeline pumping stations use large drive systems for process pumps, compressors, extruders, and fans. The ACS800-704LC-2150-7's high current capacity supports the large motors typical of these applications while the active front-end technology ensures compliance.
