What does UPS mean?

Uninterruptible Power Supply (UPS) or Uninterruptible Power Source (UPS), is an electrical equipment that provides emergency power to a load when the input power source fails or drops to an unacceptable voltage level. UPS contains mainly three basic components, a battery, a charger, and an inverter. The primary role of UPS is to provide short-term power during unexpected power outages and also react quickly to a power surge or fluctuations. The main three general categories of UPS are off-line (standby), online (no-break) and line-interactive.
