An Uninterruptible Power Supply, or UPS, is an electronic device that provides an alternative electric power supply to connected electronic equipment when the primary power source is not available.
Unlike auxiliary power, a UPS can provide instant power to connected equipment, which can protect sensitive electronic devices by allowing them to shut down properly and preventing extensive physical damage. However, a UPS can only supply energy for a limited amount of time, typically 15 to 20 minutes.
Although its use can extend to a virtually unlimited list of applications, in past years the UPS has...
