Powerbox introduces the POWERBOX Digital Interface (PDI), enabling digital monitoring, diagnostics, fault management and remote control of compatible power supplies via CAN or I²C.
Powerbox supports research into high-power-density power electronics and DC-DC converters through collaboration with STC Research Centre, Mid Sweden University and ENIT.
Powerbox is heading to electronica 2026.
Explore Powerbox’s custom engineering capabilities, standard and adapted power solutions, and developments in connected power management. Meet our team in Hall A5, Stand 312, November 10–13.
In the power electronics sector, efficiency upgrades are only valuable if they come with long-term reliability. For engineering teams deploying hardware in rugged industrial, defense, and mission-critical medical settings, understanding component-level validation data through JEDEC, EPSMA, and PSMA frameworks is the ultimate way to de-risk a project.
Powerbox announces an agreement to transfer ownership to Hypax, marking the next step in the company’s long-term growth while ensuring full continuity for customers and partners.
Reliable power systems for harsh environments require more than standard power conversion. Discover how PRBX ruggedized AC/DC and DC/DC power platforms support stable operation in defense, transportation and industrial applications exposed to vibration, thermal stress, unstable voltage and demanding operating conditions.
New higher‑voltage variants of COSEL’s HFA3500TF series extend output up to 300 VDC, giving designers greater flexibility to build compact, scalable high‑voltage systems with up to 1000 VDC using series configurations.
Powerbox is committed to powering a more sustainable future by reducing environmental impact across our entire value chain. Grounded in a five-pillar framework, we are engineering smarter, more compact power solutions to achieve a 20% reduction in emissions by 2030.
Discover how power decisions shape system success. Learn why a system-level approach to power architecture reduces risk and strengthens long-term performance.
Modern defense, industrial automation and transportation systems often operate where traditional power supplies fall short, requiring silent, reliable, fan-free solutions that withstand dust, shock, vibration, temperature swings and 24/7 operation.
Diamond is showing potential to outperform both silicon and wide band gap semiconductors in power electronics.
Wide band gap (WBG) semiconductors like gallium nitride (GaN) advance power electronics with higher efficiency, faster switching, and greater power density, though adoption faces challenges.
In a world increasingly shaped by the urgent need for climate action and social responsibility, PRBX (Powerbox) is a shining example of how industrial technology companies can lead with purpose. From the very beginning, PRBX has embedded sustainability into its core mission—not just as a corporate responsibility, but as a foundational pillar of its innovation and long-term strategy.
COSEL has just unveiled the full-brick DCS1400B, an incredibly robust, high-efficiency, high-voltage DC/DC converter (HVDC converter) delivering up to 1400W, that is perfect for harsh environments and rugged applications.
For over five decades, our company has specialized in designing power supplies for challenging applications, honing our expertise through this extensive experience.
On April 30, 2024, COSEL Co. (COSEL), Ltd. entered into a capital and business alliance agreement with LITE-ON TECHNOLOGY CORPORATION (LITEON) and has been promoting business collaboration under the joint vision of COSEL and LITEON to “Become a Worldwide Leading Brand in Standard Power Solution.”
For the power designer, any new technology that improves performance while making products smaller and more energy efficient is a very exciting concept — we’re talking holy grail territory.
