Ericsson BMR91120/1R4 200W DC/DC converter (24V to 48V) for base station power systems. Tested and in stock at Tech-Star.

The Ericsson BMR91120/1R4 is a 200W DC/DC converter module, converting a +24V input to a 48V output for use within Ericsson base station power distribution systems. DC/DC converters of this type are used where a site’s available power rail does not match the voltage required by the base station’s internal cards, allowing equipment designed around the standard telecom -48V/48V power convention to be powered from a 24V source without a separate mains-connected power plant. Rated at 200W, this module is sized for subrack or cabinet-level conversion duties rather than powering an entire site, and is designed as a modular, replaceable unit within Ericsson’s power system range.

Tech-Star (UK-based, shipped worldwide) supplies this BMR91120/1R4 200W DC/DC converter as a tested, working pull from decommissioned Ericsson base station equipment, suitable for operators and telecom resellers needing 24V-to-48V power conversion spares.
