DC Power Systems: modular −48 V up to 4000 A
High-efficiency modular −48 V DC power for telecom sites and data centers, from 1U embedded systems to the 4000 A dual-rack flagship, with hot-swap rectifiers, N+1 redundancy and integrated distribution and battery management.
One DC power platform, rack to 4000 A
FIBER OCEAN DC Power Systems package high-efficiency −48 V rectification, integrated distribution and battery management into embedded, rack and floor-standing formats, so you can power a single telecom cabinet or a full central office from the same engineered platform.
Modular hot-swap rectifiers
50 A and 75 A rectifier modules (RM4850 / RM4875) with N+1 redundancy, hot-swap replacement and ≥ 96% peak efficiency.
Integrated distribution
DC distribution panels, customized main distribution boards (MDBs), LLVD/BLVD battery contactors and field supervision built into the frame.
Smart monitoring
MCU-SM32Z controller with RS232 / RS485 and SNMP, dry-contact alarms, battery management and remote supervision.
Indoor, outdoor & hybrid
19″ subracks, floor-standing cabinets and weather-rated outdoor / hybrid variants rated for operation down to −40 °C.
DC Power Systems line-up
Modular DC power systems
FO-DC-48 series 19″ and embedded systems for telecom cabinets, BTS and edge sites, scaling in 50 A / 75 A module steps.
ExploreLarge-capacity DC plants
Floor-standing cabinets up to 3000 A (FO-DC-483000) and a 4000 A dual-rack flagship (2 × 2000 A, 224 kW, ≥ 96.6% efficiency) for central offices and hyperscale data centers.
ExploreOutdoor DC systems
Fanless, IP65 DC Lite systems (FO-ODCL-4802 / 4803 / 4806, 2–6 kW) with LiFePO4 backup for pole, rooftop and cabinet-free sites down to −40 °C.
ExploreHybrid DC systems
Multi-source hybrid cabinets with MPPT solar charging, blending grid / genset with renewable / solar and LiFePO4 backup for off-grid and poor-grid sites.
ExploreRectifier modules
RM4850 / RM4875 hot-swap rectifier modules, the shared building blocks across every FO-DC power system.
ExploreEngineered edge, rack to 4000 A
One DC power platform across telecom cabinets, central offices and off-grid sites, built for uptime, efficiency and low OPEX. Full specifications live on each category page.
One platform, 30 A to 4000 A
Embedded, 19″ rack, cabinet and dual-rack builds share the RM48xx module and MCU controller, so spares, training and expansion carry across the entire fleet.
Lower energy cost, PF ≥ 0.99
Up to ≥ 96.6% efficiency and near-unity power factor cut energy loss, cooling load and OPEX at every site and at hyperscale.
Rugged on any grid
A wide 85–300 Vac single- or three-phase input rides through unstable and poor-grid supply, keeping the DC bus stable where the mains is not.
Protected and dependable
Class C surge protection, input / output breakers and over- / under-voltage and over-temperature shutdown back a ~100,000 h module MTBF.
Compact, high power density
4000 A / 224 kW from two 600 × 600 mm racks, plus 1U embedded shelves for edge sites, pack maximum power into minimal floor and rack space.
Telecom-grade, standards-built
Engineered to IEC, ETSI and Telcordia, so one platform passes carrier and data-center acceptance across regions.
Which DC system fits?
Match the site to the right platform, then open its page for the full specifications. Every option shares the same RM48xx modules and controller, so you can standardize spares and expand capacity later.
- Single cabinet, BTS or edge site: Modular DC power systems
- Central office or hyperscale core: Large-capacity DC plants
