Explanation
A UPS (Uninterruptible Power Supply) protects network equipment from voltage variations, such as surges, spikes, sags, and power outages. It provides battery backup and regulates power to ensure clean, stable electricity reaches the devices. MDF (Main Distribution Frame) is a wiring infrastructure, not a power protection device. Power strips may offer convenience but usually provide no protection from voltage issues unless they include surge suppression (even then, not regulation). PDU (Power Distribution Unit) distributes power but does not regulate or protect against voltage Only the UPS actively protects against voltage variations.
