The most-ordered product is not in the catalog. Premium's catalog runs about 260 standard products. Its history runs more than 900 custom designs, from 50 W to 60 kVA, engineered by a Barcelona R&D team of roughly 50 engineers. When a spec falls outside every catalog envelope, custom design at production volume is Premium's normal business, not an exception.
What the datasheet will not tell you: there is no datasheet. A worked example: a 27.5 kW peak custom DC bus supply engineered for the stage motor drives of a semiconductor lithography tool, delivered cleanroom-direct. If your spec reads like that, the right first step is a conversation, not a catalog search.




Not every application needs a custom design. Premium's roughly 260 standard products cover the conventional envelopes: DC/DC, inverters, chargers, rectifiers, DC UPS, and drives, with industrial communications across the line (Modbus, CAN, Ethernet, PMBus, SNMP, RS-485/232, and IEC 61850 on the substation families) and the Premium Vision gateway when telemetry needs to reach a cloud or SCADA layer. We will tell you honestly when the standard unit is the right answer.
