Description
DC power distribution cabinet for TP483000D AC-DC indoor separated communications power system
Rated output voltage: -48 V DC
Maximum output current: 3000 A (load current ≤ 2500 A; battery charge current ≤ 500 A)
Include one power distribution detection module
The TP483000D is a new-generation AC-DC indoor separated communications power system with large capacity, high reliability, and optimal performance. It consists of the AC power distribution cabinet, DC power distribution cabinet, and rectifier cabinet. One rectifier cabinet delivers a maximum current of 3000 A. By being configured with different AC power distribution cabinets, rectifier cabinets, and DC power distribution cabinets, the TP483000D can deliver a current of 2000 A to 6000 A.
