Distributed power systems (telecommunication power supply)

Abstract

The author examines the application of distributed power supplies for telephone exchange loads in the range of 200-4800 A. The traditional central supply (locally termed the Integrated Power Suite or IPS) by comparison is seen to be deficient in areas of floor area requirements and flexibility. A cost comparison further shows the deficiency of IPS. The application of very small (combination rectifier/battery units) and medium-sized power modules for large telephone loads is examined for cost and flexibility.<>
