Understanding Uninterruptible Power Supplies: Guide to Choosing Between UPS Line Interactive and Online

An uninterruptible power supply ( UPS ) is vital for maintaining power in the event of an interruption in the normal flow of power. In this article we explained the general characteristics for choosing a UPS, today we explain the main differences between line interactive UPS and online UPS. While both protect electronic devices from blackouts or voltage spikes, they have significant differences.

Line Interactive UPS: Accessible and Reliable

The most common line interactive UPS units work via an internal battery which is charged by the normal flow of current. In the event of a blackout, they provide energy for a limited period. Their technology compensates for voltage variations, ensuring a stable current. They are economical, simple to install and ideal for protecting appliances from damage due to short outages.

Online UPS: Complete and Continuous Protection

Online UPSs, more expensive but efficient, provide energy constantly from the battery recharged by the current flow. This ensures uninterrupted protection, ideal for businesses that require absolute power continuity, such as data centers.

How to Choose the UPS Suitable for Your Needs

To choose the right UPS, evaluate the power needed, the available budget and the type of use. For personalized assistance, contact the Oniroivew team. We are ready to recommend the correct UPS based on the power absorbed by your devices and the autonomy time required in the event of a blackout.
