High Reliability Outdoor Telecom Power Supply 48V 30kW DC System for 5G Communication Base Stations
Overview of 48V 30kW DC Power System
Designed for high-capacity outdoor communication base stations, central offices, and edge computing nodes, this 6U 30kW Outdoor DC Power System delivers exceptional power density and operational reliability in a compact, space-saving form factor. With a maximum output capacity of 30kW, the system is fully compatible with 48V DC telecom infrastructure, making it an ideal power backbone for 5G macro sites, BBU pooling, and transmission equipment.
Robust AC Input & Surge Protection of 48V 30kW DC Power System
The system accepts 380VAC three-phase input (3P+N), equipped with a 1×63A 3P+N MCB for safe and convenient circuit isolation. To withstand harsh outdoor electrical environments, an integrated 20kA 8/20μs surge protection device (SPD) is installed on the 3P+N line, providing robust defense against lightning-induced transients and grid voltage spikes, ensuring uninterrupted operation even in storm-prone regions.
Flexible and Reliable DC Distribution of 48V 30kW DC Power System
On the DC side, the system offers comprehensive battery and load management. Four 125A/1P battery breakers support parallel battery strings, enabling extended backup time and flexible capacity expansion. The load output is clearly divided into two categories: six 63A/1P LLVD (Load Low Voltage Disconnect) outputs for non-critical loads, and two 63A/1P plus two 32A/1P BLVD (Battery Low Voltage Disconnect) outputs for critical loads, ensuring that essential communication equipment retains power during deep battery discharge events.
High-Efficiency Rectifier & Intelligent Control of 48V 30kW DC Power System
The system houses plug-and-play 10 pcs of 3,000W rectifier modules with up to 96% peak efficiency, significantly reducing operational electricity costs and heat dissipation requirements. All modules are managed by the advanced MC2900 controller, featuring real-time voltage/current management, battery temperature compensation, remote monitoring via SNMP/Modbus, and smart charge/discharge algorithms that prolong battery service life.
Compact 6U Design of 48V 30kW DC Power System
Packaged in a rugged 6U rack-mount enclosure, this system minimizes floor space footprint while delivering industrial-grade durability. It is an ideal choice for operators seeking a high-power, energy-efficient, and intelligent outdoor power solution that meets the demanding requirements of next-generation telecom networks.
