Product Description Negative 48V DC Telecom Power
The ETP48300 005 combines DC load distribution battery branch protection surge protection and intelligent monitoring in one compact power shelf. The front panel layout is clearly divided into AC input AC SPD LLVD BLVD battery monitoring and signal terminal areas which helps engineers identify each function quickly during installation inspection and maintenance.
With separated LLVD and BLVD output branches the system can assign different backup priorities to critical and non critical telecom equipment. This design helps extend battery backup time protect the battery from deep discharge and improve power continuity for base stations transmission rooms and outdoor communication cabinets.
