The ABB ACS800-704LC-2150-7 IP00 Drive Supply Unit is a heavy-duty, open-chassis power supply module engineered for integration into custom-built multidrive cabinets and industrial control enclosures. Manufactured in Finland to ABB's exacting ACS800 series standards, this used unit (SKU: 73326) delivers a formidable 2200A DC output at 513-932Vdc  making it the backbone power conversion stage for large industrial drive systems, marine propulsion controls, and high-power processing machinery.

Unlike enclosed standalone drives, the IP00 open chassis design of the ACS800-704LC is intentionally engineered for cabinet-integration applications. The absence of an external enclosure allows OEM switchboard builders, systems integrators, and plant engineers to mount this 195 kg drive supply within a custom IP-rated cabinet tailored to the specific environmental conditions, cooling architecture, and spatial constraints of the target installation. This design philosophy provides maximum flexibility for applications where standard enclosed drives cannot meet the dimensional, thermal, or ingress protection requirements of the end-use environment.

At Auto2mation, we have thoroughly inspected and tested this used ACS800-704LC-2150-7 drive supply, confirming all power semiconductor stages, the DSMB-03C Rev.F control board, and the DC output bus are operating within ABB specifications. This unit offers substantial savings compared to new replacement costs, making it a cost-effective solution for system retrofits, emergency spares programs, or budget-conscious multidrive projects.

Product Overview: ABB ACS800-704LC-2150-7 IP00 Drive Supply

The ABB ACS800 series stands as one of the most successful and widely deployed industrial AC drive platforms in history. Introduced in the late 1990s and refined through two decades of continuous production, the ACS800 family powers everything from steel mill roller tables to offshore drilling top drives, cement kiln rotation systems to cruise ship propulsion.

The ACS800-704LC-2150-7 occupies a specialized niche within this product family as a drive supply unit (DSU) rather than a complete motor drive. In ABB's multidrive architecture, the DSU performs the critical AC-to-DC conversion function, taking three-phase AC mains power and converting it to a regulated DC bus voltage. This DC bus then feeds multiple inverter modules (such as ACS800-104 or -704 inverter units) that control individual motors throughout the machine or process. This centralized power architecture reduces component count, improves energy efficiency through common DC bus regeneration, and simplifies maintenance in multi-motor installations.

The model number encodes the product configuration precisely: ACS800 identifies the drive family; 704 designates the drive supply unit type for multidrive systems; LC indicates liquid-cooled construction (the preferred cooling method for high-power drives where ambient temperatures are elevated or space is constrained); 2150 specifies the nominal DC current rating of 2150A; and 7 denotes the 690V AC voltage class.

This unit carries the DSMB-03C Rev.F control board, the main processor and interface board responsible for PWM control of the IGBT power modules, communication with the drive control network, protection monitoring, and status feedback. The DSMB-03C is compatible with ABB's DriveWindow and DriveWindow Light commissioning software, enabling comprehensive parameter configuration, fault diagnostics, and performance monitoring through a PC interface.

Industrial Applications for the ACS800-704LC-2150-7

The ABB ACS800-704LC multidrive supply unit serves as the power conversion backbone in some of the most demanding industrial environments on earth. Its combination of ultra-high current capacity, liquid cooling, and cabinet-integration design makes it indispensable in:

Metal Processing & Steel Industry

In hot and cold rolling mills, galvanizing lines, and continuous casting machines, the ACS800-704LC powers multiple large motors simultaneously. The common DC bus captures regenerative energy from decelerating rollers and feeds it back to accelerating sections, reducing net energy consumption by 15-30% compared to single-drive configurations. The IP00 chassis allows mounting in sealed, air-conditioned electrical rooms where steel dust and high ambient temperatures would compromise standard enclosed drives.

Marine Propulsion & Thruster Systems

Dynamic positioning (DP) vessels, cruise ships, and offshore supply vessels rely on ACS800 multidrive systems for azimuth thruster and main propulsion control. The 690V rating matches marine medium-voltage distribution standards, while liquid cooling enables reliable operation in compact engine rooms where air-cooled equipment would overheat. The open chassis design accommodates custom marine-rated enclosures with vibration isolation and salt-air corrosion protection.

Mining & Material Handling

Large conveyor systems, crushers, grinding mills, and hoists in open-pit and underground mining operations require rugged, high-power drive systems. The ACS800-704LC's robust Finnish construction withstands the shock, vibration, and contaminated atmospheres typical of mining installations. Custom IP65 cabinets protect the open chassis from coal dust, ore particles, and moisture.

Pulp & Paper Processing

Paper machines, wood chippers, digesters, and calendar stacks utilize ACS800 multidrives for coordinated multi-section speed control. The 2200A DC bus capacity supports the largest paper machine configurations with 20+ motor sections. The liquid cooling system integrates with the mill's existing process water infrastructure.

Oil & Gas & Petrochemical

Onshore and offshore drilling rigs, pump jacks, gas compressors, and refinery process equipment employ ACS800 drives for motor control in hazardous and non-hazardous areas. The open chassis can be installed in purged or pressurized cabinets meeting ATEX and IECEx certification requirements for Zone 1/2 hazardous locations.

Cabinet Integration Best Practices

Integrating an IP00 drive supply into a custom cabinet requires careful attention to several engineering factors:

• Cabinet Sizing & Clearances: The D4 frame requires adequate clearance for airflow (if auxiliary air cooling is used), cable entry/exit, and maintenance access. Follow ABB's dimensional drawings for minimum side, top, and bottom clearances.
• Liquid Cooling Circuit: The LC cooling system requires connection to a facility cooling water loop or dedicated chiller. Use corrosion-inhibited coolant, maintain flow rates per ABB specifications, and install temperature and flow sensors for interlock protection.
• IP Rating Selection: Choose the cabinet IP rating based on the installation environment: IP20 for clean electrical rooms, IP54 for dusty industrial floors, IP65 for outdoor or washdown environments.
• Input Protection: Install appropriately rated fuses or circuit breakers on the AC input side. Size conductors per IEC 60364 or NEC Article 430 based on the 1796A input current.
• DC Bus Connections: The DC output bus must be properly rated for 2200A continuous current. Use laminated bus bars with adequate cross-section and bolted connections torqued to specification.
• Grounding & Shielding: Follow ABB's EMC guidelines for cable shielding, grounding practices, and segregation of power/control wiring to prevent electromagnetic interference.
• Commissioning: Use ABB DriveWindow software to configure parameters, run self-tests, and verify operation before connecting production loads. Verify cooling system operation before applying power.
