In this video Mike Elms, Technical Manager for UPS Ltd, discusses the uninterruptible power system modules that make setting up and engineering UPSs much more easy for engineers. The solution is a unique, modular, scalable and flexible UPS which has parallel redundant UPS modules. The advantages of these are that they are built in a vertical rack so that the modules can be removed easily and no rear access is required. Mike explains that if an engineer comes to identify a problem they can then see which module is defected and replace it with another hot-swappable module. He continues to explain if additional uninterrupted power system capacity is needed then more modules can easily be slotted in.
