| High Light | 2U 9kW telecom power shelf ，Compact -48V DC power system ，Telecom power shelf for edge communication | ||
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.
2U low-profile structure for limited cabinet space and compact telecom racks.
3–9kW modular power capacity with up to three 3kW rectifiers.
150A maximum output current for small and medium DC load systems.
Front In / Front Out cabling for easier wiring and cleaner installation.
Hot-pluggable rectifier and controller for online replacement and reduced downtime.
Battery management function helps protect backup batteries and extend service life.
Integrated AC SPD and DC SPD for surge protection on both input and output sides.
LCD controller with LAN, RS485 and SNMP for local display and remote monitoring.
Dry-contact alarm outputs and AI/DI signals support integration with site alarm systems.
IP20 indoor protection level for rack or cabinet installation.
The ET48150-001 is suitable for wireless base stations, fiber access cabinets, microwave transmission points, enterprise communication networks, railway and expressway communication nodes, small telecom rooms, edge network cabinets and distributed -48V backup power sites.
