The Green Cell UPS with 1800W is an online model. It has an under-acute conversion, which is based on the fact that the voltage from the socket is first converted from AC to DC, supplying the battery charger. In the next step, the battery is the power source for the inverter, which already supplies the connected devices with alternating current. The technology used guarantees an uninterrupted power supply, without having to switch to battery power, because the inverter constantly draws current from the energy storage. The power supply is equipped with a cold start function, i.e. forcing the battery operation to start without connecting to the mains. This function is useful e.g. when it is necessary to start up a desktop computer with a current power outage.
The appropriate daily ór power supply of the UPS provides security for the connected devices and power supply until e.g. saving the edited fileów. The power supply is equipped with AGM Green Cell batteries with a life span of more than 5 years. The back-up time depends mainly on the power of the connected device and the appropriately selected UPS model, so it is worth remembering that when choosing a UPS, the power of the connected devices should not exceed 80% of its nominal value.
The Green Cell UPS has the same voltage shape at its output as the current in the electrical outlet. This is due to the pure sine wave. Thanks to the power supply being equipped with additional elements, the device is widely used. Due to the online operation of the UPS, it is mainly used to power and protect servers. It is ideal as a protection of sensitive devices against damage due to fluctuations in the network or in the event that the mains power outage makes it impossible to record the effects of our work. The pure sinusoidal design of the UPS protects the capacitive or inductive devices connected to it, such as CO pumps or refrigerators. It is often used to power both cash registers and alarm systems - devices that provide safety and the possibility of continued operation. 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 should be emphasized that a UPS is not only a backup power supply in the event of a power outage, but also a guarantee of safety for often expensive equipment 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].
Devices often have the power given in Watts [W]. To obtain the value in VA, the total power of the devices in Watts should be multiplied by a factor of 1.4. It should be remembered that the power of the PSU is about 20-30% higher than the total power of the protected devices.
