What Is A UPS (Uninterruptible Power Supply)?
Uninterruptible power supply systems, or UPS for short, provide a backup source of electricity to buildings in the event of a blackout. A UPS system will continue to power equipment even if there is an outage and can also help keep your data safe from being corrupted by sudden voltage fluctuations. In this article, we’ll explore some different types of uninterruptible power supplies and how they work.
Types of UPS
UPS systems are designed to keep your equipment running if there is a power outage for whatever reason. The three types of UPS systems, Standby, Double Conversion, and Line-interactive can be used in different settings depending on the power requirements but both serve an important function when it comes to keeping you up and running during a crisis.
It’s especially critical for businesses with expensive computer hardware because they need that electricity 24/7 without interruption which means as soon as one goes down, everything else stops too (unless there was another backup system like a battery). That being said, all these devices have their own limitations so make sure you understand them before deciding where or how much investment will go into this type of device.
1. Standby UPS
The standby UPS is the simplest of three options for power protection. It acts as a backup battery when the main power source exceeds permissible limitations or fails, and it will also convert that to DC current in an instant so you can keep your devices running long after any outage—just make sure they’re plugged into the converter!
Most standby UPS feature a switch that allows them to run on either the main power supply or the battery. Because this is an inverter, it has two modes: AC and Battery. When in AC mode, electricity coming from your wall outlet goes through what’s called an “AC/DC rectifier” which converts it into DC current before being fed into a large storage unit known as a “battery.” This then travels via another converter system (known as DC/AC) so you can use any of those fancy electronics while working off of batteries instead! Advantages of using a standby UPS:
- The Standby UPS is easy and affordable
- Instantly convert AC to DC power for devices during blackouts
- Battery backup will protect your electronics from power surges or outages when the main source fails
- Allows you to work off of your batteries even when using AC
- IC protects it from power surges which can lead to appliances being damaged and costly repairs
- Provides up to 10 minutes of backup time in the event of a blackout/surge
2. Double Conversion UPS
The DC/AC inverter automatically switches to the battery when there is a power outage, eliminating any transfer time. This increased efficiency and protection makes it ideal for industrial use or where emergency backup power is required.
The double-conversion UPS’s constant connection with both primary source of electricity as well as the rechargeable batteries means that switching over will not be interrupted by waiting on an offline period before connecting back up again – leading to better performance against spikes, sags, electrical noise, and total power loss in case of emergencies requiring a continuous supply of electricity. Benefits of using a Double Conversion UPS:
- Save time and money by eliminating transfer time in power outages
- Reduce the need for costly battery maintenance
- Twice the power means energy savings
- A safe and reliable product that is built to last
- Less downtime during periods of storms or emergencies
3. Line-interactive UPS
The line-interactive Uninterruptible Power Supply (LIUPS) is a more advanced version of the standby UPS that has an additional component called a “transfer switch.” The transfer switch pulls power from the electrical grid and uses it as backup, but if there’s no connection to the main source or voltage dips below permissible limits, this device will take over by using its batteries until everything returns to normal. It works in conjunction with other devices like generators to help avoid any need for manual switching during these events including having the benefits of having the following:
- More power supply reliability
- Increased runtime for generator
- Protects electronics from surges and spiking voltage levels
- Provides safety against unforeseen events
The UPS you choose should be based on the applications your equipment needs to run. If you need a reliable, efficient, and cost-effective UPS for light sag or surges that is also suitable for data centers, intensive care units, or motor applications, then line-interactive would be best. However, if you want protection from larger sags and longer outages with minimal transfer time like at-home computers, printers, or scanners—then standby is perfect!
