Ericsson ROF1377857/1 POU68V5V5V multi-rail power output unit for the MD110 / MX-ONE PBX.

The Ericsson ROF1377857/1 is a POU68V5V5V power output unit board within the Ericsson MD110 / MX-ONE digital switching platform. As its designation states, it is a multi-rail DC/DC power converter delivering regulated 6.8V and 5V outputs, converting the exchange’s central battery supply into the low-voltage rails needed by the logic circuitry on boards fitted in the same LIM (Line Interface Module) or power magazine.

Stable low-voltage power is essential in a digital exchange, feeding processor, memory and interface boards that keep calls connected, and converter faults are a common cause of localised board problems. This is a legacy component from Ericsson’s MD110 / MX-ONE family, still running at many enterprise and campus sites worldwide.
