EPowerSys

What EPowerSys does

EPowerSys is the commercial brand of NEUREUS TECHNOLOGIES, S.L., a privately held Spanish engineering company founded in 2006 and headquartered in Madrid with manufacturing in Sueca, Spain. The company designs and manufactures high-stability programmable DC power converters (RPSu series, 750W-12kW), high-precision DCCT current transducers, impulse winding testers (CDG 7000), current measuring and calibration systems, and custom-engineered power supplies. Its core technology is built on zero-flux DCCT-based closed-loop control, Vienna Rectifier PFC topology, Peltier-based active thermalization, zero-voltage switching, and optical-fiber-driven switching semiconductors, collectively delivering sub-2ppm long-term current stability for demanding magnet and current-measurement applications.

The company primarily serves particle accelerator and Big Science facilities (CERN, KEK, GSI, BARC, STFC, JINR, Princeton Plasma Physics Laboratory, IFMIF, ESS Bilbao, RIKEN), with the CDG 7000 documented as standard magnet-testing equipment at CERN. Secondary segments include industrial applications (semiconductor, ATE, data center), universities, and medical/fusion research laboratories. Its engineering team includes former CERN staff, providing domain specialization that anchors its credibility in the niche.

EPowerSys generates revenue through direct enterprise field sales of custom and semi-custom engineered hardware, with a quote-based pricing model (no public list pricing). It operates a two-segment sales structure (Big Science and Industry) and reaches international customers through a network of nine regional distributors covering the USA, Japan, India, China, France, the UK, the Netherlands, Italy, and Brazil. The company holds ISO 9001:2015 certification and is privately held with no disclosed external funding.
