Ericsson 09021000461D08202005 RBS radio base station Power Supply

The Ericsson MCM02/A (09021000461D08202005) is a power supply module used within Ericsson’s RBS (Radio Base Station) family of GSM/WCDMA base station cabinets. As part of the RBS power distribution subsystem, the MCM02/A converts and regulates the site’s incoming DC supply for use by the cabinet’s radio, baseband and control subracks.

This helps protect sensitive electronics from variations in the site’s main power feed and provides the module-level power management that Ericsson’s modular RBS cabinets rely on. Power modules of this type are field-replaceable, allowing a faulty unit to be swapped without disturbing the wider cabinet.

Ericsson’s RBS platform was deployed extensively across 2G and 3G mobile networks from the late 1990s through the 2000s and remains in service at many legacy and refurbished sites today, with power modules such as the MCM02/A being one of the most commonly replaced field spares. Tech-Star supplies this power supply module as a tested, like-for-like spare for operators and maintenance contractors supporting existing Ericsson RBS deployments.
