The Three Major Types of UPS System

Types of UPS

Here are the three types of UPS systems that are available

The Offline UPS System: An Offline UPS System charges its battery while the primary power source is available and switches to battery power only during a blackout. These systems activate only after a power failure, resulting in a temporary shutdown of your equipment. Although less expensive and more energy-efficient than other options, Offline UPS Systems are not appropriate for critical loads and are not recommended for such purposes.

Line Interactive UPS Systems: Line Interactive UPS Systems sit between offline and online UPS systems. These systems rely mainly on the main power source and also have voltage stabilization filters to counteract spikes and transients. Unlike offline systems, line interactive UPSs offer a higher level of equipment protection.

Transformers enable a UPS to maintain a steady output voltage to critical systems – without switching to and from battery power – whilst the mains voltage is within the range of approximately +20% to -30%, resulting in far fewer load breaks and reduced battery wear.

Online UPS Systems: Online UPS Systems have a continuous connection between their batteries and inverter, eliminating the need for a power transfer switch. During a power loss, the rectifier disconnects, and the batteries maintain a consistent and uninterrupted power flow. If the primary power source deviates from the preset parameters or fails, the battery begins to discharge while keeping the load unaffected. The critical aspect of online UPS systems is that power always flows through the UPS, with the only change in the event of a primary power failure being the discharge of the battery, ensuring no interruption in the load.
