Soft cover. Zustand: New. 2nd Edition. From the back cover: dc Power System Design for Telecommunications is a must-have resource for anyone responsible for designing, installing and maintaining telecommunications systems or systems that require very high reliability. The text explains how to design direct current (dc) power sys…tems that operate at nominal voltages of 48 and 24 volts dc, use lead-acid batteries, and are installed in telecommunications systems and other exclusive use environments. Readers acquire the skills and knowledge to perform systematic analyses to make the best choices based on several economic, operational, electrical and physical considerations. Written in a straightforward style that avoids unnecessary jargon and complex mathematics, the text covers: Detailed descriptions of the seven major system components: Rectifier/charger system, Battery system, Charge bus, Discharge bus, Primary distribution system, Secondary distribution system, and Voltage conversion system Detailed descriptions, design equations, reference tables, block diagrams and schematics Design procedures to select the most appropriate power system elements, such as buses, wiring, overcurrent protection, rectifiers, and batteries Application of American National Standards Institute's telecommunications industry standards and other relevant standards, practices and codes Strategies for dealing with voltage drop in distribution and battery circuits as well as guidance for sizing circuit wiring to meet voltage drop and current rating requirements In-depth discussions that focus on the types of lead-acid batteries used in telecommunications and their applications Throughout the text, examples demonstrate how theory is applied to real-world telecommunications systems. Some 330 illustrations and more than 100 tables are also provided to help readers visualize and better understand complex systems. Design and application examples and accompanying solutions help readers understand the design process and use their new skills.
