  • About the Edition

    An important part of any communication system is its power supply system. The smooth operation of all communications depends on the quality of the power supply and on the operational reliability of the increasingly complex equipment and devices used for this purpose. This book describes current power supply technologies, it explains the circuit techniques using easy-to-understand examples and illustrations. Also covered are automatic control, grounding and protection techniques as well as the design of battery and grounding installations. The book is conceived as a practical guide for those involved in planning installing, comissioning and servicing telecommunication systems, but it is also useful as an introduction to the subject.

    Delta’s telecom power systems are designed for wireless broadband access, fixed-line applications, Internet backbone and datacenters. Our reliable, energy-efficient telecom power solutions protect against grid power interruptions and fluctuations and help . 5G technology requires powering hundreds of small antennas. in cities, malls and buildings.. We have solutions for you, whether the antennas are powered: directly from the grid,; using an existing infrastructure,; or by an innovative “micro-grid” topology. Metro Grid is our micro-grid solution based on a DC distribution. Developed with a major telecom OEM, it secures antennas saving money.

The power supply lab designs all power-related subsystems incorporated in INTRACOM TELECOM products according to international safety and electromagnetic compatibility specifications. The lab has accumulated considerable know-how in the design and testing of power supplies, telecommunications power supplies and defense application power supplies.

    In October , the company signed a supply agreement to deliver up to 30, units to provide backup power for wireless communications towers in India. The agreement called for IdaTech to supply 5 kW fuel cell systems (minimum order of 10,) to the ACME Group, a leading supplier of passive infrastructure to the telecommunications. go to our circuits - one for positive power supply and one for negative (ground, or GND). Please also read chapters 2 and 3 in our course book “Physical Computing” (pp. 9 ) in addition to following the following examples, descriptions and experiments: We take our power supply and cut off its plug - we want to replace it with a header.

Beyond telecommunications, optical fibers can also transport optical energy to powering electric or electronic devices remotely. This technique is called power over fiber (PoF). Besides the advantages of optical fiber (immunity to electromagnetic interferences and electrical insulation), the employment of a PoF scheme can eliminate the energy supplied by metallic cable and batteries.
