Power - DC/DC Converters, Inverters, Battery Chargers and UPS Systems

Most power supplies are bought from a catalog, and most of the time that is fine. The projects that get expensive are the ones where the spec does not quite fit: a non-standard bus voltage, a 400 Hz load, a peak-to-average ratio the catalog unit cannot carry, an enclosure that will not take the standard footprint. That is usually where the compromises start, an oversized unit, an extra conversion stage, efficiency given away.

Three things worth knowing before you settle for the compromise, none of which show up on a datasheet comparison:
1. Custom is not a special order here. It is the operating model. Roughly 50 of Premium's 130 people are R&D engineers, and the company has delivered more than 900 custom designs in its history, from 50 W to 60 kVA. When your spec falls outside a catalog envelope, the practical question is not which unit comes closest. It is whether custom engineering pays at your production volume. With a team that does this daily, it does more often than most engineers expect.
2. A rail certification stack is a ruggedness proxy. Most of Premium's families carry EN 50155 (rail electronics), EN 45545-2 (rail fire safety), and EN 61373 (shock and vibration). If your platform is a mobile robot, a marine autonomous vehicle, or an outdoor enclosure in a storage yard, equipment qualified for rolling stock has already been engineered for a harsher life than most industrial power supplies ever see. Documented MTBF figures run 100,000 to 1,000,000 hours, with operating ranges to -40 / +70 C and IP66/IP67 options.
3. Verification speed lives in the factory, not the datasheet. Premium tests in-house in Barcelona: a semi anechoic EMC chamber, climatic and accelerated-aging chambers, dielectric strength to 15 kV, and an ISO certified cleanroom that ships lithography-grade product directly into customer cleanrooms. Full test documentation is available on request. In practice that means the qualification loop on a custom or modified design runs through one building instead of a chain of third-party labs.

One honest note: Premium product is built to order out of Barcelona. We plan the delivery schedule with you honestly at quote time, and we will tell you plainly when a project timeline calls for an off-the-shelf unit instead.

Rail and transit. Premium's deepest pedigree: onboard inverters, catenary DC/DC, chargers, and drives certified to EN 50155, EN 45545-2, and EN 61373, plus substation power for the wayside.
Semiconductor and high-tech equipment. Custom DC bus supplies for motor drives and process tools at production volume, cleanroom-direct delivery, and the EMC discipline tool builders qualify against.
Energy, storage, and microgrids. Substation chargers and rectifiers, DC UPS for protection relays, fuel cell conversion architectures, and grid-tied conversion for storage systems.
Robotics and autonomous platforms. Battery-to-AC inversion for onboard loads, custom DC/DC for non-standard rails, and ruggedization that started life in rolling stock.
Mission-critical facilities. DC UPS for controls and network layers, and sub-2 ms static transfer switching where a dropped AC source is not an acceptable failure mode.

Bring us a one-line diagram, a spec that will not fit a catalog, or just the application. We will talk through:

What the input really is: voltage window, transients, and where it sags or spikes
What the load really needs: continuous versus peak, and for how long
Whether a catalog unit covers it, a modified standard closes the gap, or the spec justifies a custom design at your volumes
The certification set the application actually requires, stated honestly per family
Footprint, cooling, and mounting, since power density only matters inside your enclosure

You walk away knowing whether Premium fits, what the right architecture looks like, and what the honest schedule is. If a catalog unit from someone else is the better answer for your timeline, we will say so.
