Source-to-rack direct current portfolio for Ai data centres.

Helps maximise energy efficiency and reduce physical footprint, alongside DC power distribution and protection technologies to enhance overall system performance.

Infinitus is a portfolio of direct current (DC) solutions designed to manage the increasing power demands of Ai data centres from ABB. The portfolio accelerates the adoption of DC architectures in data centers improving energy efficiency and reducing power infrastructure footprint, while increasing available computing capacity. ABB expects other energy-intensive industries to make the same transition.

The International Energy Agency (IEA) expects global data center electricity demand to more than double by 2030 and ABB estimates that approximately 25-40% of new capacity installed in 2030 could be using DC distribution. Next-generation Ai chips are expected to draw 1 MW per rack and beyond, an increase from today’s almost 200 kW, requiring a shift to DC architecture that can support performance while driving energy efficiency. With 800 VDC distribution, the footprint is more compact while eliminating redundant conversion steps and cutting heat losses of conventional alternating current (AC) systems. A recent BCG / ABB report calculated that DC distribution delivers energy efficiency gains of more than 5% and increases available space for compute racks. For a 500MW data center, a 5% efficiency gain can mean 25 MW more power for revenue-generating IT loads and more than US $300 million (€232m) in potential additional revenue per year. With 5% efficiency gains for a 500 MW data center campus, the energy savings over one year would be equivalent to powering Washington D.C. for almost a full week.

Giampiero Frisio, President of ABB’s Electrification business area, said: “ABB has pioneered DC technology for more than 25 years across several segments. We are working closely with chipmakers, hyperscale customers, supply partners and industry bodies to set the standards and the pace for the roll-out of high-efficiency DC architectures. Infinitus is the first portfolio providing the building blocks for any data center architecture - either DC native or hybrid AC/ DC - to power next-generation Ai chips efficiently. This technology will bring similar energy efficiency gains to other energy-intensive industries such as large scale manufacturing, renewables and marine operations.”

Infinitus is the industry's first integrated source-to-rack DC portfolio. At its core is ABB’s breakthrough Infinitus solid-state transformer technology, enabling sites to operate with a smaller footprint and greater energy efficiency. As the only major electrification supplier with both the world's first fully IEC-certified solid-state circuit breaker and an industry-first static medium-voltage UPS in production, ABB delivers a breadth of technology unmatched in the market. 

ABB’s Infinitus DC portfolio includes five key building blocks:

• Medium Voltage Powertrains deliver stable resilient power from the grid or on-site generation;
• DC Sources and Power Quality converts AC to DC removing conversion from white space;
• DC Power Distribution delivers power safely and reliably, enabling higher power density in a smaller footprint;
• DC Power Protection provides protection for operators, iI servers and hardware from DC overcurrents;
• Cooling Optimisation reduces energy consumption across grey and white space with DC connected variable speed drives and motors.

ABB works with customers to design solutions tailored to their specific power demands, facility layout, and energy mix. This partnership approach ensures each deployment is optimised for maximum efficiency and reliability. The Infinitus portfolio complements traditional AC systems with DC flexibility that supports customers across all power architectures while also enabling unprecedented efficiency, reliability, and scalability for AI-era data centers.

For next-generation data centers, this integrated architecture enables the high-density, high-efficiency power delivery that future Ai chips demand. With a number of main components produced in the next twelve months, the first DC-native facilities using the complete Infinitus portfolio are expected to be installed and operational within two to three years.

The portfolio launch extends support for ABB's continued collaboration with NVIDIA, first announced in October 2025, to develop 800 VDC power architectures for gigawatt-scale Ai facilities. ABB brings more than 25 years of DC experience and over 700 patents spanning renewables, power generation, energy storage, motors and drives.

Multifunctional DC energy meter.

The trend towards efficient utilization of limited resources has led to the introduction of a host of activities for energy efficiency improvement. For DC systems especially, monitoring their performance and error-free operation is fundamental. Photovoltaic and battery storage systems are particularly relevant here and the focus is also evidently on the power supplies of emerging electromobility solutions.

SIRAX BM1450

In the case of photovoltaic systems, energy efficiency is normally monitored at string inverter or inverter level. To do this, each string of a PV module or the individual inverter is measured in order to capture operating data such as voltage, current and power in both DC as well as AC.

This data shows the productivity of the system and also provides the operator with early indications of possible problem areas.

Camille Bauer's  SIRAX BM1450 multifunctional DC energy meter was designed for the measurement and monitoring of DC systems. With four independent channels and multi channel support, it is ideal for bidirectional voltage and current measurement. The DC energy meter can be used to measure the energy consumption of four independent loads as well as charging and discharging currents. The measurement data can be parametrized directly on the device using two pushbuttons or via the RS485 Modbus RTU interface. Four integrated relay outputs allow the user to implement functions such as triggering a pulse output for additional external counters or for implementing time-delayed tasks.

The outputs can be activated by an external limit switch for example or other remote triggers. Measurement results can be displayed locally on the large 4-row LED display or sent via Modbus RTU to a higher-level system, (such as the SMARTCOLLECT data management system from Camille Bauer Metrawatt AG) for display and further processing.

Camille Bauer Metrawatt products are marketed in Ireland by Irish Power and Process.

High Power Regenerative DC Load.

The ELR9000 HP Series of regenerative, programmable electronic DC loads has been introduced by Intepro Systems. This latest version of their ELR Series is designed to accommodate three-phase mains between 360V – 528V AC. The increased power density of HP Series units provides load ratings of up to 15kW in a single 3U rack-mounted instrument. A master-slave bus can be used to connect as many as 16 units in parallel to test loads of up to 240 kW. A unique feature of the ELR 9000 HP Series is an integral, grid-synchronized inverter designed to return up to 94.5% of the load test energy back to the grid. 

“The wide input voltage of the new ELR 9000 HP Series of electronic DC loads is especially important to our customers who have manufacturing facilities in multiple global locations,” said Gerard Sheehan, Intepro's Chief Technical Officer. “In addition, the regenerative output is even more valuable in these higher power density units, eliminating the need for expensive cooling systems used by conventional air- and water-cooled loads to dissipate energy as heat.”

The ELR 9000 HP Series offers four common regulation modes: constant voltage, constant current, constant resistance and constant power. The FPGA-based operational controls include a function generator and a table-based regulation circuit for the simulation of non-linear internal resistances. Intepro’s PowerStar 6 software package enables the creation of test routines using a drag-and-drop menu where coding can be performed without programming.

3KW DC Power Source.

Intepro Systems has introduced the PSI 9000 2U programmable DC power source, providing a 1-3KW supply with a feature set typically found in higher power 3U systems. The PSI 9000 2U power source features an interactive system with touch panel menu navigation that simplifies set up and storing to test profiles.

The high-efficiency (up to 93%) unit includes an integrated true function generator. For user convenience, complex test sequences can be loaded from the system and saved to a standard USB flash drive.

A unique feature of the PSI 9000 2U power source is its auto-ranging output. Unlike competitive DC sources that provide rated power only when maximum voltage is applied to the load, the auto-ranging output stage is capable of delivering a three-times higher output current at reduced voltages. This feature is especially useful when testing products that require varied input voltages while maintaining regulated output power. With auto-ranging, a single system provides a complete test solution, compared to buying multiple sources to address low- and high-voltage/current requirements.

“The new PSI 9000 2U power source includes all of the features and functions of its higher-power ‘3U’ cousin,” said Gerard Sheehan, Intepro's Chief Technical Officer. “This easy-to-use unit has front panel controls that include an intuitive LCD display and control knobs for setting voltage, current, power or internal resistance simulation values.”

Additional features of the RoHS-compliant PSI 9000 2U power source includes a galvanically isolated analog interface for voltage, current and power programming and monitoring; digital plug-and-play modules supporting RS232, Ethernet, CANopen, Modbus TCP, Profibus, Devicenet; and IEEE/GPIB and SCPI command language support.
