Also known as an uninterruptible power source, this is an electrical apparatus that provides emergency power to a load when the input power source, typically the mains power, fails. Due to Eskom’s regular load shedding, this happens a lot. The primary role of any UPS is to provide short-term power when the input power source fails, but they can also help with other problems like power surges, which seems to be common before or after a load shedding series. Why do you need a UPS? Power problems are the second leading and most preventable cause of computer downtime. Power problems are the leading cause of data loss, 15 times more frequent than computer viruses. Power disturbances account for about one-third of all server failures.
