A UPS system is a battery backup power, a UPS system
also provides surge protection against power problems, like surges or abnormal
voltages, which can damage, reduce lifespan, or affect the performance of
connected devices.
In
case of power loss, the UPS system immediately activates to provide a
continuous power source.
When choosing a UPS system:
Power Source: Single-phase or Three-phase
Topology: Standby, Line-Interactive, or Online
Waveform: Sinewave or Simulated sine wave
Size: Capacity in terms of wattage
Runtime: Duration of power bridge
Monitoring: The status of your UPS
Form Factor: Desktop/Compact, Tower, Rack/Tower, or
Rackmount
Other considerations: Connections and Equipment

Single-conversion systems
In normal operation, these feed incoming utility AC power to IT
equipment.
Double-conversion systems
As the name suggests, these devices convert power twice. First, an
input rectifier converts AC power into DC and feeds it to an output inverter.
The output inverter then processes the power back to AC before sending it on to
IT equipment.
Multi-mode systems
These combine features of both single- and double-conversion
technologies while providing substantial improvements in both efficiency and
reliability:
