Ruggedized, high-efficiency DC/DC, DC/AC, AC/DC and AC/AC platforms from 50 W to 72 kW — designed, qualified and manufactured in Europe.
Proven railway and industrial platforms with documented EN 50155 test evidence, wide input ranges and fast availability for retrofit or series production.
From magnetics and resonant topology selection to environmental qualification and 20-year obsolescence management for critical fleets and plants.
Most projects start with a catalogue platform and evolve into a tailored build. Both routes share the same design rules, qualification methods and traceability, so you keep reliability while controlling NRE and schedule.
More than 260 qualified products, the majority held in stock for immediate shipment. Selected topologies, conformal coating options and documented type tests let engineering teams de-risk a design in days rather than months.
Over 40 years and 1,000 designs of accumulated know-how. We convert a demanding specification — thermal envelope, isolation, EMC profile, footprint, redundancy — into a manufacturable, certifiable and supportable product.
Every family is dimensioned for real duty cycles: catenary transients, battery cranking, regenerative loads, altitude derating and unattended operation in extreme temperature.
Isolated railway and industrial converters with wide 2:1 and 4:1 inputs, high peak-power capability and galvanic isolation up to several kV.

Every market carries its own normative framework and failure cost. Our RDI and Quality departments define the certification path project by project, from rolling stock fire safety to substation EMC and data-center availability targets.
On-board and wayside converters engineered to EN 50155, EN 45545-2 and EN 61373.

Explore high-tech → Rectifiers, chargers and auxiliary supplies for substations, wind and storage plants.
Explore energy → Ruggedized units for shock, salt mist, wide temperature and long-life programs.
Explore defense → Redundant DC architectures and monitored power paths for continuous availability.
Explore data centers →Reliability is designed in, not tested in. Our process makes thermal, magnetic and electrical margins explicit before the first prototype is built, which is why our units survive decades in rolling stock and unattended installations.
Rolling-stock builders, utilities, semiconductor equipment makers and energy groups rely on our converters in mission-critical assets.
