| High Light | 10U telecom DC power system ，modular rectifier power system ，industrial DC power supply | ||
A new high-capacity -48V DC power system developed for medium-to-large telecom power applications that demand higher output current, stronger distribution capability, and greater redundancy. Designed for central offices, regional aggregation sites, large wireless hubs, edge data centers, industrial control networks, and utility communication rooms, this system provides stable DC supply for critical network equipment under demanding operating conditions.
Built on a robust 10U rack-mount platform, the system integrates high-efficiency rectifier modules, intelligent monitoring, battery management, AC/DC distribution, and fault protection into one centralized power architecture. It is intended for customers who need not just power conversion, but a complete telecom energy platform that supports long-term growth, easier maintenance, and centralized supervision.
What Makes This Model Different
Higher Capacity for Larger Network Loads
This system is designed for installations where conventional small DC shelves are no longer sufficient. With up to 24 kW output, it can support a larger number of telecom, transmission, routing, switching, and industrial communication devices from one centralized platform.
Redundancy for Mission-Critical Sites
The rectifier section can be configured with N+1 redundancy, which means the system can continue operating even if one power module fails. This feature is especially important for telecom backbone, transport networks, and critical control environments where downtime is costly.
Distribution and Protection in One Platform
Instead of relying on multiple external distribution boxes, the system can integrate battery access, DC branch protection, AC input management, and alarm signaling in one rack unit, helping simplify the entire site power architecture.
Intelligent Visibility for O&M Teams
The controller continuously supervises voltage, current, battery condition, temperature, fan operation, module status, and active alarms. Combined with remote communication interfaces, the system helps operators improve troubleshooting speed and reduce maintenance workload.
