There is no doubt that Uninterruptible Power Systems are integral to the con-tinuous supply of clean power for mis-sion critical infrastructure. In order to understand the UPS systems and their influence on reliability, an overview of UPS terminology, concepts of integrat-ing UPS systems, static systems, rotary systems, redundancy, configuration, batteries, and energy storage systems will be discussed.

Upon the successful completion of the course, participants will be able to:
• Describe the basic building blocks of UPS Systems
• List typical Power Quality Problems
• Detail the operation of the popular UPS Systems
• Maintain and test Lead Acid and Nickel Cadmium Batteries
• Apply Safe working practice for UPS’s and Batteries
