Introd uction 2 1.0 I NTRODUCTION 1.1 System Description The role of the parallel-redundan t multi-module UPS system is to supply uni nterruptible, clean power to the critical load. The UPS main tains a full-vol tage, low-distortion output, even if the u tility source power sags, becomes distorted or fails. If there is an outage of the so urce powe[...]

Introd uction 3 In the unlikely event of a fault wi thin the UPS, the SCC control logic, which continuously monitors all critical circuits within the UPS system, transfers the load to bypa ss without interruption and simul- taneously activates local and remote al arms. If a fault is d etected in an indivi dual UPS module, tha t module is automatica[...]
