  "textContent": "A power control system may include an uninterruptible power supply (UPS), a display device, load measurement circuitry to determine a load percentage of the UPS, and a controller. The controller may receive the load percentage of the UPS from the load measurement circuitry; monitor the load percentage of the UPS to determine whether the UPS is operating in a nominal load state or an overload state; generate an input overload countdown timer when the UPS is operating in the overload state, where the input overload countdown timer provides an estimated time remaining in the overload state; generate an output overload countdown timer by applying a minimum envelope filter to the input overload countdown timer; and direct the display device to display the output overload countdown timer. Additionally, the minimum envelope filter may be operated in an open-loop or a closed-loop configuration.",
