Online double-conversion – These UPS systems provide your facility the highest level of protection by isolating the equipment from raw utility power. The system works by converting power from AC to DC and then back to AC. This unit is the only UPS that provides power with zero transfer time to the battery, making it ideal for sensitive
Understanding Uninterruptible Power Supply (UPS): Offline, Online, and Line-Interactive Systems. An Uninterruptible Power Supply (UPS) is a critical piece of hardware that provides emergency power to a load when the input power source or mains power fails. This power protection system offers near-instantaneous protection from
All online and many line-interactive UPSs offer this capability. When choosing between line-interactive and online uninterruptible power supply, it often comes down to price. Line-interactive UPSs cost up to 40 percent less than online UPS systems. However, if you can''t afford even one millisecond of downtime, an online UPS may be
The Line-Interactive UPS is cheaper than the Online Double-Conversion UPS and requires less maintenance. It also consumes less power, reducing energy costs. However, the Line-Interactive UPS does not provide complete isolation between the input and output power sources. This makes it susceptible to certain power disturbances, such as harmonic
There are three topologies of UPS systems: offline vs line-interactive vs online. What are their differences and how to choose the right UPS system for your design? This article will make a comparison among these three designs in four aspects:

The line-interactive UPS operates similarly to the offline/standby UPS in that it typically supplies the critical load through the bypass line and then transfers it to the inverter in the event of a by-pass supply failure. The line-interactive system utilizes the battery, charger and inverter in the same
Because a standby UPS offers only the most basic level of protection, the majority of organizations choose to deploy either a line-interactive or a double-conversion online model. Before making this decision, it is important to understand the differences between the two topologies. Consider the following five key factors: 1. Your power
First lets examine three common types of UPS systems: Offline UPS, Line-interactive UPS, and Online double-conversion UPS Offline. Offline UPS units are often referred to as standby systems, as
While both UPSs provide full protection from major power problems, such as surges, spikes, sags, blackouts and brownouts, they differ in a few significant areas. Simply put, an on-line UPS offers a higher level of protection than a line interactive at a higher cost. More specific areas where the two types differ include sine wave output
A line interactive uninterruptible power supply is a hybrid device that adds some form of voltage regulation feature in the bypass line to conventional off-line UPS designs. Like off-line models, a line interactive UPS supplies the critical load through the bypass line and transfers it to the inverter in the event of a bypass supply failure.
Additionally, an online UPS can provide long periods of battery runtime by adding extra battery packs. Standby and Line-interactive. Standby and line-interactive UPSs turn on the inverter when the power fails and can only provide short periods of battery runtime (by design). This leads to an interruption (transfer time) when the inverter power
A: The main difference between line-interactive and online UPS is the way they regulate power supply. Line-interactive UPS regulates power supply and switches to battery backup during power outages, while online UPS continuously powers devices from the battery and regulates the power supply.
Line-interactive UPS is similar to offline UPS in its circuits but enhanced by the adding a transformer (voltage regulator) to condition the utility power. It slightly improves efficiency and reduces battery usage. Though Line-interactive UPS is not as reliable as Online-UPS, it is still prevalent among the consumer and IT professional markets.
A true online, double-conversion UPS provides 100% power conditioning, zero transfer time to battery, no change in output voltage and better transient suppression than line-interactive units. Online double conversion is Online systems also provide frequency regulation, essential for use with backup generator systems to protect from variations
Line-interactive UPS technology provides power conditioning with a 4-6 millisecond break in power when transferring to battery back-up and protects against the most common power problems experienced in a network. Here the UPS also monitors the voltage level and balances under and over voltages. This technology provides a good choice between
When not operating from the battery, line-interactive UPS systems typically regulate output within ±8-15% of the nominal voltage (e.g. 120, 208, 230, or 240 volts), whereas online UPS systems typically regulate voltage within ±2-3%. In fact, there are some common power issues that may occur in daily operations.
In one of our Newbie''s Nook segments, we briefly touched on the differences between the three types of single-phase UPSs: standby, line interactive, and online.That post focused on basics of each device handling a power issue; this post is focused, specifically, on the differences between line interactive and online UPSs in order to find the best fit for
The major point that differentiates between the online UPS and offline UPS is that the online UPS supplies power from the AC mains to the Load through the rectifier and inverter combination while the Offline UPS directly supplies power from AC mains to the load. Before going to the list of differences between Online UPS and Offline UPS, let''s
Line-interactive UPS technology possesses the ability to correct minor power fluctuations without switching to battery. This type of UPS is equipped with an autotransformer that regulates low and over voltages, enabling it to handle brownouts and swells. Line-interactive models are also suited for consumer electronics, gaming systems, PCs, and
And because they produce less heat than on-line models, they are well-suited for installations with limited cooling capacity. A line-interactive UPS typically regulates output within +6 to -14% of the nominal voltage, while an
ys on and connected to the output.Line interactive UPS systems are a cheaper option than online double conversion technology and will protect a critical load from power failures, power sags, power surg. s, under-voltage and over-voltage. Unlike the online double conversion topology, it will not protect against electrical line noise, frequency
There are three main types of UPS battery backup, categorized by how they work: standby, line-interactive and on-line. Standby models provide a basic level of protection from power problems. Line-interactive models provide a higher level of protection than standby models, and on-line models provide the highest level of protection available. Let
The main difference between Online UPS and Offline UPS is that the Online UPS provides the power with the help of rectifier and inverter combination. It simultaneously provides power to load as well as the battery so that battery can be charged to supply power in case of power failure. On the contrary, an Offline UPS supplies AC power directly
