What Premium PSU does

Premium PSU (legal entity Premium, S.A.) is a privately held Spanish power conversion systems manufacturer founded in 1981 and headquartered in L'Hospitalet de Llobregat, Barcelona. The company designs and manufactures DC/DC converters, DC/AC inverters, AC/DC rectifiers, battery chargers, AC/AC variable frequency drives, and UPS systems — spanning 40W to 72kW — using Silicon Carbide (SiC) and Gallium Nitride (GaN) semiconductor technology to achieve efficiency up to 94.3% in compact, ruggedized form factors. Its portfolio of 260+ standard products and 900+ custom designs (since 1981) targets railway, energy, defense, high-tech industrial, and (via the Floox sub-brand) EV charging markets, with extensive certifications to EN 50155, EN 45545-2, EN 61373, ISO 9001, ISO 14001, CE, UKCA, and RoHS/REACH.

Revenue mechanics combine direct B2B enterprise sales (consultative, with engineering involvement for custom solutions), a direct e-commerce storefront for catalog items, and consultative custom-design engagements with 14-week prototype lead times. Customers include Alstom, ASML, Siemens, Vestas, Iberdrola, Endesa, CAF, and Naturgy across railway rolling stock, semiconductor manufacturing equipment, energy generation and distribution, and wind sectors. Distribution is global (5 continents), with active participation in InnoTrans, Middle East Energy, OCP EMEA Summit, and EDS Summit. The company has 130+ employees including a 50+ engineer R&D team, and engineering, test laboratory, and production are co-located at the Barcelona facility for tight design-to-manufacturing integration.

Strategic activity in 2025–2026 includes a CEO transition (Ezequiel Navarro succeeding founder-era CEO Jordi Gazo), entry into the Open Compute Project for 800 VDC data center power architectures, participation in the European ALL2GaN GaN technology consortium, and recent product launches covering modular SiC rectifiers (FlexStorm), railway catenary inverters (OVX-6400), and modular redundant DC/DC converters (CKR-3600). The new CEO has publicly articulated a goal of scaling the company into the €50–100M revenue range.
