Even though UPS systems are used to regulate the changes occurring in circuits, they do not include any protection against instantaneous overvoltage. Indeed, there is only a tiny low conductive filter in UPS products, and this filter provides protection against radio-frequency interference only. Many companies consider uninterrupted power supplies (UPS) as overvoltage protection systems. However, UPS systems do not provide protection against instantaneous overvoltages that lead to damage.
