Using a two-level PCB construction, the baseplate of the converter has all the key semiconductors attached, allowing direct cooling into the system chassis, heatsink or cold-wall. With efficiencies to 92% and the ability to remove heat to the outside world, minimal waste-heat is generated into the system and this keeps the internal ambient temperature rise to a minimum.

The PSUs have a 90-264VAC input range and six models are available with 12 to 58VDC output, plus a built-in 12V fan rail. Both industrial and medical versions meet EN55032level B; the industrial unit is also is certified to IEC/EN/UL/CSA60950-1, while the medical unit also meets medical 4th Edition EMC levels and is certified to IEC/EN/CSA60601-1 and ANSI/AAMI ES60601-1.

“Whether these units are conduction-cooled via a baseplate, convection or fan-cooled, they enable system designers to manage heat generated in the system effectively, thereby increasing product lifetime. Applications include broadcast, outdoor communications, medical devices, sealed enclosures and industrial,” said Mark Gibbons, Engineering Manager at Fidus Power. 

Free engineering samples are available on short lead-times and all models are backed by Fidus’ 5 year warranty.
