Question 1

What power range do Premium PSU power conversion systems cover?

Accepted Answer

Our standard and custom platforms cover 50 W to 72 kW in single units, and higher power through parallel or modular rack architectures with redundancy and current sharing.

Question 2

Which railway and industrial standards are your power supplies designed to?

Accepted Answer

Rolling stock and wayside equipment is engineered against EN 50155, EN 50121-3-2, EN 45545-2 fire and smoke, EN 61373 shock and vibration and EN 50124 insulation coordination. Industrial and energy units follow IEC 61010, IEC 61000 EMC and IEC 62368 requirements. Certification scope is defined per project with our Quality department.

Question 3

How long does a custom power supply development take?

Accepted Answer

A typical custom program runs from specification review to qualified samples in 16 to 28 weeks depending on approval scope, magnetics complexity and test campaign. Re-use of qualified building blocks such as planar transformers and resonant power stages shortens NRE and schedule significantly.

Question 4

Do you support obsolescence management and long-term supply?

Accepted Answer

Yes. Railway and defense programs run for decades, so we manage component life cycle monitoring, last-time-buy planning, form-fit-function redesigns and repair or retrofit services for installed fleets.
