A UPS System, also known as an uninterruptible power supply system, is widely acknowledged as a necessary product in the tech industry for its power protection services. These power systems keep the power going long enough for electronic equipment to be shut down properly, in order for data to not be lost or compromised by utility failure or a black-out, and to reduce the stress of a sudden shutdown on equipment.

There are three basic types of UPS systems, and each type of this crucial technology has its own advantages and disadvantages to consider. Here are the different types of UPS systems to be knowledgeable about.

Double-Conversion: Online

A double-conversion system offers the highest protection available, but remains a bit more complex. The incoming voltage is mainly what keeps the battery charged. An online UPS converts a stable input of AC, or alternating current, to DC, or direct current, and then converts it directly back to AC. This specific design of double-conversion (AC-DC-AC) creates a power source outside of the main power supply for security. To explain further, an online UPS takes incoming AC and converts it to DC to feed the battery and convert back to AC, which ensures no further power switches are necessary. By this online process, a double-conversion system protects from essentially all possible power disturbances.

Stand-By: Offline & Battery Back-Up

Out of the variety of different types of UPS systems, this UPS system is the most basic and cost-effective. It’s also the most common UPS system for smaller offices and personal computers at home. The system passes utility power onto your computer while it monitors any inward voltage levels. If these incoming electrical levels reach below a certain level, the UPS automatically changes its power source to the internal battery to protect data and your equipment. This battery-backup aids as a safeguard from most power surges and blackouts, but it is not the most effective out of all the systems.


This UPS system is similar to an offline system but goes a step above in protection due to its inner-workings. The extra advantage lies in improved filtering and better control over power fluctuations. As it monitors the incoming voltage, it utilizes the internal battery in order to supplement voltage that falls below predetermined levels and prevent voltage that’s above what it should be. Line-interactive UPS systems thus rely on the battery to condition the power source, meaning its battery could drain out sooner than a double-conversion process and system would.

Anything is better than nothing to provide protection service to your hardware. Each of the above UPS systems can be beneficial, but finding the UPS system that’s right for your needs may require asking an expert. No matter your choice in a UPS system, keep the system and other electronic equipment monitored as the best protection strategy.
