RRU 27V/54V Rectifier System

27/54V Rectifier System for RRU (Remote Radio Unit)

A natural cooling type controller-integrated rectifier for the supply of DC (27V or 54V) for the operation of RRU (Remote Radio Unit)
A rectifier system that can be installed on the closed case considering the RRU which is operated outside
Shares the rectifier system at the upper level controller and uses the own protection function
