EPW30-48A Emerson Emerson EPW Series Power Supply

The Emerson EPW30-48A is a rectifier power supply module designed to convert AC mains input to regulated -48VDC output for telecommunications and network equipment. This unit is part of Emerson’s EPW series of modular rectifiers, engineered to provide reliable DC power in mission-critical environments.

The EPW30-48A is typically deployed within Emerson NetSure or similar modular power systems, providing scalable power capacity for central office equipment, data centres, and telecommunications facilities. The modular hot-swap design allows for N+1 redundancy configurations and simplified maintenance without service interruption.

Emerson’s network power division, now operating under Vertiv following the 2016 spin-off, produced these rectifier modules for widespread deployment in telecom infrastructure. The EPW30-48A remains in active use across many legacy and current installations where -48VDC power distribution is standard.
