PKE4210PI

PKE 4000 I 25–40 W DC/DC Power Modules 48 V Input Series Single, dual and triple output 10.7 mm (0.42 in.), allows 0.8 in. board spacing 1,500 V dc isolation voltage MTBF > 2 million hours at +75 °C case temperature Complete, no extra filters or heatsinks required The 25–40 watts PKE 4000 series hybrid DC/DC power modules are especially designed for decentralized 48/60 VDC power distribution systems with distributed on-board DC/DC converters in applications with high temperature and isolation requirements. By using a thickfilm technology, which provides a high degree of integration as well as an efficient thermal management and by utilizing a 300 kHz switching frequency technology based on proprietary drive & control chips, the highly reliable products conform to the most stringent telecom and datacom requirements in harsh environment applications. Input to output isolation is as high as 1,500 Vdc and mechanical ruggedness in conformance to IEC 68-2 – is close to the requirements for discrete components. The converters can operate in free convection with full output power at ambient temperatures from –45 to +85°C, making the products ideal for the most de-manding temperature requirements in both indoor and outdoor tele/ datacom applications. These products are manufactured using highly automated manufacturing lines with a world-class quality commitment and a five-year warranty. Ericsson Microelectronics AB has been an ISO 9001 certified supplier since 1991. For a ...
