Lucent CSKPCBAA Cajun/CBX500/Stinger networking and access Switch / Carrier Ethernet Line Card

The Lucent CSKPCBAA is an LW015A84 board-mounted DC-DC power module, taking a 36 to 75 V input and delivering a regulated 5 V at up to 3 A, so roughly 15 W.

That input range is the standard telecom -48 V battery window with its normal tolerance, which is what this class of module exists for. Telecom and networking equipment is fed from a battery-backed -48 V DC plant rather than from mains, and each card then converts that feed locally to the low voltages its own logic needs. An isolated brick like this one is the component that does it, mounted directly on the circuit board.

Lucent Technologies made these through its power systems and microelectronics operations, and the line changed hands more than once as that business was sold on, so equivalents appear under later badges with the same LW module coding. We have removed the platform claim previously carried here: a general purpose DC-DC brick is not tied to a particular Lucent system, and the board it came from is what determines the fit. Tech-Star is UK-based and ships worldwide. Contact our sales team with the pinout or the host board and we will confirm the match.
