AC/DC modules can be adjusted over a ±20% range
The PFE-S series of AC/DC full-brick power modules, manufactured by TDK Corporation, has been updated. Now available in 12V, 28V and 48V nominal outputs, the PFE-SA series can be adjusted over a ±20% range. With the PFE300SA, full power can be delivered with a baseplate temperature of between -40 and +100°C. The 12V PFE500SA has a maximum base-plate temperature of 85°C, while the 28V and 48V models deliver the same output at temperatures up to 100°C.
Accepting a wide AC input from 85-265V at 47-63Hz, all versions of the PFE-SA series feature active PFC and an input to output isolation of 3kV for one minute. Over voltage, over current and over temperature protections are also provided, as are inverter operation good functions which enable greater flexibility in the diagnostics of the power.
The series conforms to EN/UL/CSA 60950-1 safety approvals for general purpose applications, and carries the CE mark according to the low voltage and RoHS Directives. Offering up to 4% improvement in efficiency (series maximum efficiency 91%) and a 5-year warranty, the PFE-SA series is suitable for outdoor applications and equipment requiring water-cooling, hermetic sealing, fanless operation and compact design.
