🔋 What is a UPS
-
Uninterruptible Power Supply (UPS) is a device that provides backup power when the main electricity supply fails.
- In normal operation, the UPS supplies power from the mains to your equipment. If the mains electricity is cut off or becomes unstable, the UPS automatically switches to its internal battery, ensuring uninterrupted power to connected devices.
- Many UPS units also help stabilize voltage and protect against surges, dips, and other power fluctuations — not just full outages.
- It helps prevent data loss or hardware damage when power suddenly cuts or fluctuates (important for computers, servers, networking gear, or sensitive electronics).
