The Green Cell Power Proof UPS with a nominal power rating of 480W is an offline line-interactive model - this means that it is equipped with a fully automatic voltage regulator, which has a primary function as a voltage dropout protection, it also has ró protection against mains interference. The ró allows the device to switch to battery power at a level of 2-6 ms in an instant, thus protecting our work and unsaved files from loss.
Due to its simple design, relatively low price and the use of a modified sine wave, the device is ideal as a protection of sensitive devices against damage caused by fluctuations in the mains or in case when the mains power failure makes it impossible to record the effects of our work. It is often used to power both cash registers and alarm systems, i.e. devices that provide safety and possibility to continue work. It is one of the most popular models used for office computers, treated as a protection against sudden voltage loss, which can cause the computer to shut down. Thanks to the Green Cell emergency power supply, you will avoid the situation in which it will be impossible to save your work on your computer. It is important to note that the UPS not only provides backup power in the event of a power outage, but also guarantees safety for often expensive electronics against voltage fluctuations.

Lack of stability of the power grid may have a negative impact on the operation of, among others, computers. In addition to an additional power source, the UPS guarantees stability and deprives the power source of interference. This is due to current regulation and filtration, while protecting the equipment from damage caused by lightning.
Laser printers are characterized by a power surge when switched on and during printing. Therefore, it is important to choose the correct power supply. Most often it oscillates within a few kVa.
In order to correctly select the power of the UPS, the power of all the loads that we would like to protect should be added together. An important parameter of apparent power, expressed in VA. The values are given on the equipment nameplates, otherwise multiply the voltage [V] and current [A].
The units often have the power in watts [W]. To obtain the value in VA, multiply the total power of the units in Watts by a factor of 1.4. Make sure that the power of the power supply unit is approx. 20-30% higher than the total power of the protected units.
