Choose safe and clean energy

If you've ever had to deal with power cuts resulting in equipment failure or the need to restart your computer and, to make matters worse, you've lost important data not saved on disk, we have a solution for you. With a Qoltec UPS, you'll have a constant supply of energy for the stable operation of your computer or server, and you won't have to worry about power outages or voltage drops.

Pure sine wave - highest quality and security of power supply for your devices

Qoltec's online UPS provide stable interference-free pure sine wave power. It's complete protection for your devices, thanks to the double conversion that first converts the AC of the mains supply to DC and then to AC, ensuring the highest level of power quality and protecting against potential mains disturbances such as voltage drops, power outages, surges and failures.

How does UPS Online work?

An Online UPS has a voltage that is continuously recycled, in the event of an unexpected drop in the mains voltage, the UPS maintains the operation of the connected device, thanks to the built-in batteries, which are continuously charged. Thus, mains power is only needed to charge the batteries. Permanently connected devices always receive clean energy, without interference from the battery, so the output voltage of the online UPS will always be constant, regardless of the input voltage. The back-up time of the equipment is a few minutes to several minutes, this is the time to save data and safely shut down the equipment.
