What is a UPS system?
An uninterruptible power supply allows a computer to keep running for a short period when power goes out.
When the power goes out unexpectedly, the UPS switches to battery power and inverts DC power to AC power in order to power equipment.
Most entry-level UPS systems are designed to power security systems, computers, WiFi routers, IT-related infrastructure and basic electronic equipment.
Three types of UPS
Online double conversion
These are preferred when safeguarding IT loads to protect against power outages.
It’s called the double conversion because incoming power is converted to direct current (DC) and then converted back to AC.
Line-Interactive
These provide better control over power fluctuations.
These allow higher voltage inputs, while they come with a voltage boost circuitry and a range of input voltage that the UPS accepts.
Offline/Standby/Battery backup
The standby UPS or battery backup is the most cost effective.
This choice is fast in switching to battery in order to prevent a power trip.
It can run for an effective period.
