Power electronics engineering design team at Premium PSU

1. We Design

We design, assemble, and verify functional prototypes inside our dedicated Research and Development Center. Our experienced engineering team tailors standard topologies or creates ground-up solutions to match your exact electrical, mechanical, and thermal specifications.

  • Custom planar magnetic integration & resonant topologies
  • Optimized cost-to-performance ratio for series production
  • Compliance with EN 50155, IEC 61010, and IEC 62368 standards
  • Thermal modeling, electrical stress analysis & 3D CAD design
In-house climatic and EMC laboratory testing at Premium PSU

2. We Test

We maintain an extensive in-house laboratory equipped to perform rigorous electrical, climatic, and electromagnetic qualification tests. Flexible testing protocols allow us to validate prototype units quickly and prepare complete compliance dossiers.

  • Electrical & Functional: Programmable AC/DC loads, high-bandwidth oscilloscopes & power analyzers
  • Climatic Stress: Environmental chamber cycling (-70°C to +150°C) and accelerated life thermal stress
  • Dielectric Safety: High-voltage insulation testing up to 15 kV for compliance with international safety directives
  • EMC Semi-Anechoic Chamber: In-house radiated & conducted emissions testing to EN 50121-3-2 and IEC 61000
Advanced power supply manufacturing line in Barcelona

3. We Manufacture

Every unit is manufactured at our Barcelona facility under strict quality standards. Our entire production path—from component intake and SMT/THD assembly to final packaging—operates within an integrated anti-static ESD circuit.

  • Automated optical and electrical verification to eliminate human error
  • 100% thermal burn-in under extreme temperature and full load conditions
  • Full component traceability and continuous quality tracking
  • Serialized verification test report included with every shipped supply
Controlled Environment Assembly

ISO 14644 Certified Cleanroom Facilities

To serve high-tech industrial sectors such as semiconductor manufacturing, optical metrology, and medical diagnostics, we operate state-of-the-art cleanroom environments designed to eliminate particulate contamination during final assembly and testing.

Our cleanroom installation is certified under ISO 14644 standards, giving international equipment manufacturers complete confidence when integrating power units into ultra-clean application environments.

  • Three Cleanliness Classes: Dedicated zones rated for ISO Class 8, ISO Class 7, and ISO Class 6 operational requirements.
  • Strict Environmental Control: Positive pressure, HEPA air filtration, temperature regulation, and relative humidity monitoring.
  • Decontamination Protocols: Specialized multi-stage cleaning process for components entering controlled rooms.
  • High-Precision Assembly: Ideal for power supplies mounted near sensitive optics, laser systems, or wafer processing lines.
