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 decentra-
lized 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 complete product
program please reference the back cover.
