120-W power modules suit telecom applications

The PKB5000W series of open-frame isolated 120-W eighth-brick dc/dc power modules offer nominal outputs of 3.3-, 5- or 12-Vdc with maximum outputs of up to 30 A and efficiency of typically 91.5% at 12-V full load. They feature an 18 to 75-Vdc input range and are suitable for 24- or 48-V telecom systems.

The power modules come in the industry-standard through-hole eighth-brick format, measuring 2.3 x 0.9 x 0.39-in. In addition to the open-frame version of the module, an optional baseplate version is also available for applications that require conduction cooling. They operate from –40° to +110°C and provide 2,250-Vdc input/output isolation.
