Abstract :
Considering the reliable operation of 48 V telecommunications power supply systems, it is essential for appropriate dimensioning. The basic elements of the power supply systems, i.e. batteries, rectifiers, DC/AC cabling, fuses, etc., should be defined by exact calculation. The presentation reviews the main questions and problems of dimensioning. It lays a special emphasis on the optimized planning procedure, further it also deals with the economical impacts of the dimensioning parameters
