BML351013/7 Ericsson Ericsson Power Systems Power Supply

The Ericsson BML351013/7 is an EFORE-manufactured rectifier module designed to deliver regulated DC power at 54.5V with a 5A output capacity. Rectifier modules of this type are essential components within telecommunications power systems, converting AC mains input to the stable DC voltage required by network and switching equipment.

This rectifier is intended for use within Ericsson power shelves and cabinets, typically found in mobile network base stations, fixed-line exchanges, and data transmission sites. The 54.5V output aligns with the standard -48V DC nominal range used across telecom infrastructure, accounting for charging voltage requirements.

The BML351013/7 is a legacy component from Ericsson’s earlier power system portfolio. While no longer in active production, these rectifiers remain in widespread deployment and are sought after for maintenance, repair, and capacity expansion of existing installations.
