Uninterrupted Power supply services popularly referred to as UPS, are considered one of the most important devices which work as emergency power in the case when the main power is not available. UPS comes as a relief device as it not only protects vital data of computers but it also provides protection to critical components of computers like processors and motherboards. In the absence of main utility power, the presence of UPS is mandatory for carrying out any domestic or commercial power-related task. UPS includes numerous components like input-output phases, battery packs, external, maintenance bypass switches, DC and AC adopt., etc. It is important to note, that the optimum performance of UPS can be achieved only if UPS‘s main performance and support services are carried out on a regular basis.
