Ericsson BMR91120/1 GSM / RBS Power System Power Supply Image 1

Ericsson BMR91120/1 DC/DC 200W converter module for the Ericsson RBS power subrack. Tested and in stock at Tech-Star.

The Ericsson BMR91120/1 is a DC/DC 200W, a 200-watt DC-to-DC converter module for the Ericsson RBS radio base station platform, used to step the RBS’s main -48V DC supply up or down to the secondary voltage rail required by specific radio, baseband or auxiliary cards. DC/DC converters of this type sit within the RBS power subrack alongside the main PSU and battery protection units, providing localised, regulated power conversion for equipment that cannot run directly from the -48V bus.

Tech-Star (UK-based, shipped worldwide) supplies this BMR91120/1 DC/DC 200W converter as a tested, working pull from decommissioned Ericsson RBS equipment, suitable for operators and telecom resellers maintaining or repairing existing Ericsson RBS installations.
