When it comes to keeping critical equipment protected from a power disruption, selecting the appropriate Uninterruptible Power Supply system is important. Two types of UPS systems found in residential and commercial applications are Line Interactive UPS and Double Conversion UPS. Recognizing the difference between these types of UPS systems will help ensure the protection of your sensitive equipment.
In this article, let’s take a look at line interactive UPS versus double conversion UPS.
What is a Line Interactive UPS?
A Line Interactive UPS is a style of UPS system designed to provide simple power interruption, dip and over voltage protection. It has a standard built-in automatic voltage regulator (AVR) to help reduce minor power related issues without switching to battery power. For small offices, networking equipment and home electronics, a line interactive UPS is a great option.
What are the Main Features of a Line Interactive UPS?
- Stabilizes voltage through AVR
- Uses the battery only when the power loss is significant
- More energy-efficient than some other types of UPS power supply
- Economical and easy to manage
Typically handles moderate power irregularities, but does not isolate any and all power problems. This makes Line Interactive less ideal for expensive, high-end, or mission critical equipment.
While Line Interactive UPS is capable of compensating for power fluctuations, it may not fully isolate your equipment from those issues. Therefore, it may not be the best option for higher end or critical equipment.
What is a Double Conversion UPS?
More commonly referred to as an Online Double Conversion UPS, this system provides the best level of protection. It takes the incoming AC power, turns it into DC power continuously and then converts it back to AC.
What are the Main Features of a Double Conversion UPS?
- Provide continuous power with zero transfer time
- It isolates connected equipment from all power problems
- This is ideal for data centers, medical equipment and mission critical infrastructure
- Can support longer runtimes, better reliability
Double Conversion systems are true online systems. They are used in many applications necessary to have zero downtime.
Final Thoughts
Looking for the right UPS maintenance option? It is important to consider whether a Line Interactive UPS versus an Online Double Conversion UPS is best for your situation. A Line Interactive UPS works well for most applications you will encounter on a day-to-day basis. However, if you are looking for truly clean and consistent power for sensitive applications, the Online Double Conversion is a better option.
