Technical Comparison Between Line-interactive and Online UPS Systems

Technical Comparison Between Line-interactive and Online UPS Systems - Prostar UPS

Two types of UPS systems used in server and Network are classified as Online UPS and Line-interactive UPS. These systems are basically known as UPS system’s topology. Line-interactive UPS systems are less expensive than online UPS at the most basic level but they are also less protective than the Online UPS systems. Thus, you need to understand the technical differences between these two UPS systems first. How about we consider four key UPS elements and how line-interactive and online UPS systems convey every element to associated gear:

Pure Sine Wave Output:

At the point when working from battery control, a line-interactive UPS system produces the waveform of its AC output. An online UPS does this constantly. All online and numerous line-interactive UPS systems have pure sine wave output. Pure sine wave output gives most extreme strength and predominant similarity with delicate gear. Pure sine wave power is needed by some devices power supplies and keeps others from overheating, breaking down, or falling flat rashly.

Regulation of Voltage:

Automatic voltage regulation (AVR) is used by Line-interactive UPS systems to remedy irregular voltages without changing to battery. (Switching so as to manage voltage to battery depletes your backup power and can make batteries wear out rashly.) The UPS recognizes when voltage crosses a preset low or high edge esteem and uses transformers to help or lower the voltage by a set add up to return it to the worthy extent. Online UPS systems utilize a more exact system for voltage regulation: they persistently change over approaching AC energy to DC force and after that change over the DC energy to perfect AC output power. This persistent twofold transformation operation separates associated gear from issues on the AC line, including power outages, brownouts, over voltages, surges, line commotion, consonant mutilation, electrical driving forces, and recurrence varieties. In “line” mode (i.e. at the point when not working from battery), line-interactive UPS systems ordinarily manage yield inside ±8-15% of the ostensible voltage (e.g. 120, 208, 230 or 240 volts). Online UPS systems regularly control voltage inside ±2-3.

Exchange Time to Battery:

Amid a blackout, line-interactive UPS frameworks commonly exchange from line energy to battery-inferred power inside of two to four milliseconds, which is more than sufficiently quick to keep everything except a little rate of the most power-touchy devices working without interference. Online UPS frameworks don’t have an exchange time in light of the fact that the inverter is as of now supplying the joined devices load when a blackout happens.

Surge Protection:

All Online UPS Systems incorporate surge concealment and line commotion sifting segments to shield your gear from harm brought about by lightning, surges, and electromagnetic (EMI/RFI) line clamor. Online UPS frameworks offer predominant protection in light of the fact that the twofold transformation operation secludes gear from issues on the AC line.
