This UPS Training course begins with a discussion of the need for UPS systems. It then covers the relative comparisons between various UPS topologies and their modes of operation. The batteries used for UPS systems are also covered How a battery works, their maintenance, safety and testing is throughly discussed.
A solid working knowledge of the typical electrical and electronic components found within a UPS system is explained, as well as how AC is converted to DC and then inverting DC back to AC. When all of the above elements of a UPS are understood, a theoretical rectifier and inverter feedback loop are throughly discussed. This will be followed by a testing and troubleshooting section. Students will be given failure scenarios where they will learn how to determine which circuit component has opened, shorted or significantly changed in value to produce the alarm condition described. The course finishes with a general discussion on UPS system testing and maintenance procedures.
Some working knowledge of basic electrical engineering principles is required, although this will be revised at the beginning of the course. Real-life experience in working with batteries and UPS systems will enable the course to be placed in context.
After completion of the course the delegate will be able to:
