ET48150001 2U 9kW Compact -48V DC Telecom Power Shelf for Access Networks and Edge Communication Sites

The ET48150-001 is a compact 2U -48V DC telecom power shelf designed for access-layer communication equipment, small base stations and edge network cabinets where installation depth, wiring convenience and fast maintenance are important. Compared with larger 5U power systems, this model focuses on a lighter structure and lower rack-space occupation while still providing rectification, battery connection, protected load outputs and intelligent monitoring in one integrated unit.

The system supports a capacity range of 3kW to 9kW, using up to three 3kW rectifier modules. With a maximum output current of 150A, it is suitable for powering transmission devices, microwave equipment, fiber access units, switches and compact telecom loads. The front-access design allows AC input, battery circuits, load breakers, controller interface and signal terminals to be handled from the same side, which is useful for wall cabinets, indoor racks and narrow maintenance spaces.
