UPS Solutions can assist is finding the rights Smart UPS product to suit your application from the range below.
Smart UPS SC
Entry Level Smart UPS for Home Office and Small Business. The SC series has line conditioning, battery back-up and offers basic shutdown communications to a single device via Powerchute software.
The Smart UPS SC ranges from 420 VA to 1500 VA.
Smart UPS
The standard smart UPS series is for small to medium size businesses and is ideal for both desktop and server environments. The Smart UPS offers line conditioning and a pure sine-wave output to ensure a high level of protection to the load in all modes. The Smart UPS is a line interactive device.
All Smart-UPS units come with a Smart Slot, so an optional Network Management Card can be installed. This enables the UPS to be given an IP address and allow for alerting and alarming via the network and safe shutdown of multiple devices in the event of power failure.
The Smart UPS comes in both tower and rack mountable form factors from 750 VA to 5000 VA.
Smart UPS – Extended Run
Smart UPS extended run has the same technical properties as the standard Smart UPS except with the added benefit of scalable run-time. The Extended run series has the ability to add additional battery packs to increase the run-time of the system in the event of power failure. His is an ideal range for companies that have the need for very long runtimes and need to maintain business continuity through extended power failures.
Please refer to our UPS Runtime chart to find the right amount of XR battery packs you require.
Smart-UPS extended run models can take up to 9 additional battery packs, taking your run-time to multiple hours.
Smart-UPS Online
The Smart-UPS Online is the top of the Smart UPS range. It offers an online design, meaning there is no transfer time to battery if power is lost. It's double conversion design ensure the highest level of protection to extremely critical IT loads as well as other delicate equipment that cannot handle a switchover delay.
All of the Smart-UPS Online units are designed to be extended run. And can take up to 9 additional battery packs.

UPS Topology – Why is an Online UPS Different to a Standard UPS?
Online UPS
An online UPS offers double-conversion topology: The inverter is connected in series between the ac input and the load. Power for the load flows continuously through the inverter. An online UPS has some of the same components as an off-line UPS with a few differences — most notably, a rectifier. An online UPS has input surge protection, batteries, inverter components and a rectifier. The rectifier takes the input voltage and changes it from ac voltage (alternating current coming from the utility power) to dc voltage to charge the battery and provide dc power to the inverter. In most online UPSs, the rectifier or filtering is used to make sure that the load, as well as the UPS, does not allow unnecessary noise and harmonics to be fed back into a building's power. Because an online UPS is always creating its own power from the rectifier and inverter, it never has transfer interruptions and can provide a higher level of power quality.

Line-Interactive UPS
With the line-interactive topology, the inverter is connected in parallel and acts to backup utility power. It also charges the battery. Through its reversible operation, it interacts with utility power to stabilize the voltage.
The line-interactive UPS requires a transfer time for the inverter to turn on and to supply power to the load. This is the main difference between an On-Line UPS and a line-interactive UPS.
