Distributed Power System
Introduction
Distributed Power System (DPS) is a new generation power solution,
specialized for compact site. It consists of DC module, AC module &
battery module. It supports pole-mounted and wall-mounted. DPS can
be widely used for macro site, small cell and remote RRU.
DPU30D : DC module, converts AC/HVDC to -48Vdc, supplies 3
branches of DC output and 1 branch for battery
DPU30A : AC module, supplies constant 3 branches of AC output and a
branch of DC output for battery unit or DC load
DOU-DCD01
