This is a compact highly capable -48V DC power system developed for telecom operators, system integrators, and infrastructure providers that need stable DC supply in limited installation space. It is particularly suitable for outdoor communication cabinets, FTTx nodes, compact BTS sites, wireless backhaul equipment, and industrial networking enclosures where footprint, front-access maintenance, and system reliability are critical.
Its modular design allows flexible expansion as site load grows. Operators can start with fewer rectifier modules and add capacity later without replacing the entire system, which helps control initial investment and simplifies network expansion.
Space Efficiency Without Sacrificing Function
The 4U profile is designed for locations where rack space is limited but dependable DC power is still required. It fits neatly into 19-inch racks, compact communication cabinets, roadside telecom boxes, and edge enclosures.
Stable Operation in Unstable Power Environments
With a wide AC input range, the system can continue operating under fluctuating mains conditions often found in rural, remote, or mixed-grid environments. This makes it suitable for distributed telecom deployments where incoming power quality may not always be ideal.
Battery Backup Management Built In
The controller supports battery charging, float management, equalization control, low-voltage disconnect, and alarm supervision, improving backup power reliability and extending battery service life.
