ABB has introduced a range of power equipment designed to deliver electricity more efficiently to AI servers. Several main components are expected to enter production within 12 months, with the first data centers using the full range due in two to three years.
The Infinitus range uses 800-volt direct current, or DC, to carry power through a facility. ABB says it can serve data centers designed around DC as well as those combining it with conventional alternating-current systems.
A solid-state transformer converts incoming medium-voltage AC electricity into 800-volt DC. Moving that conversion outside the server area reduces the equipment needed near computing racks and the number of times electricity must be converted before reaching them.
The range also includes equipment for connecting to the grid or on-site generation, distributing electricity to rows of servers and protecting hardware from excessive currents. Motors and variable-speed drives control pumps and other cooling equipment to reduce their electricity use.
ABB’s product documentation includes battery storage and equipment that helps steady voltage and respond to changes in electricity demand. The company plans to configure installations around each customer’s power needs, building layout and energy supply.
The launch builds on ABB’s collaboration with NVIDIA, announced in October 2025, to develop 800-volt power systems. NVIDIA is preparing for server racks drawing a megawatt or more and has targeted 2027 for the start of the transition.
In its technical explanation, NVIDIA describes how the 54-volt systems used within existing racks become harder to accommodate as power demands grow. The power supplies and copper conductors needed at megawatt scale take up space that could otherwise hold servers. Higher-voltage distribution allows power conversion to move out of the rack.
Electricity still has to be converted to the lower DC voltages used by processors. NVIDIA also identifies safety standards, staff training, fault protection and maintenance as work needed to support the change.
ABB cites calculations from a study with Boston Consulting Group suggesting DC distribution could improve energy efficiency by more than five percent. Its example assumes a five-percent gain at a 500-megawatt data center, making 25 megawatts available for computing. These are projected benefits of the design.
ABB estimates that DC distribution could account for 25 to 40 percent of new data-center capacity installed in 2030. The company expects the first facilities using the complete Infinitus range to be operating two to three years after the September launch, following production of several key components over the coming year.
