An invaluable and uniquely comprehensive reference guide for all those who specify, purchase or work with Uninterruptible Power Supplies (UPS’s), the new UPS Handbook from Eaton.

With 35 information-packed A4 pages which are extensively illustrated with photographs and diagrams, the handbook covers every aspect of UPS selection and operation. It also provides a complete guide to power quality with useful additional information such as a basic introduction to electricity, a glossary of power terminology and even a table of worldwide supply voltages.

Special attention is given to reasons for using UPS’s to protect critical systems and an explanation of the nine most common power problems, which include power failure, power sag, under- and over-voltage, electrical noise and harmonic distortion. Also treated in detail are the major UPS topologies and the types of application for which each is most suitable, along with the factors that need to be considered when deciding between centralised and decentralised systems.

Other sections of the handbook deal with batteries, including factors that affect battery life; software for managing and monitoring UPS installations; and service, including details of popular types of service contract – a vital but frequently overlooked aspect of UPS system operation.

In addition to general information applicable to all types of UPS, the handbook also includes sections dealing specifically with Eaton products, which are available to handle loads from just 350VA up to 1MVA and more. Eaton proprietary technologies and their benefits are explained, including the environmentally friendly Energy Saver System (ESS) and Variable Module Management Systems (VMMS), as well as Advanced Battery Management (ABM) to optimise battery life, and the Hot Sync system for dependable load sharing.
