The Qoltec Line Interactive UPS power supply is a modern device that ensures stable operation of the connected computer even in the event of a power outage.It meets the requirements of anyone who wants to have control over the stable operation of their device regardless of fluctuations in the power supply.DISCOVER SECURE ENERGYEach of us has often dealt with voltage drops at home or at work. Sometimes. their only consequence is the need to restart the computer. But how many times have you lost important data due to such an event. data that wasnt saved on the disk. or encountered a device failure? If the above situations are familiar to you. we have a solution that will address problems caused by power outages or voltage drops. The UPS Qoltec 850VA 480W uninterruptible power supply is the solution that ensures a constant flow of energy necessary for the stable operation of your computer.MODIFIED SINE - SIMPLE DESIGN. REDUCED FAILURE RATESDevices that do not require a pure sine wave. such as computers. laptops. or other data processing devices. will work without any issues with a UPS with a modified sine wave. It produces an output sine wave with an alternating voltage of an approximated (modified) waveform. whose effective value is the same as the value of the sinusoidal waveform present in the power grid. This type of power supply is primarily characterized by lower failure rates and a simple design.HOW DOES A LINE INTERACTIVE UPS WORK?The UPS Line Interactive power supply operates based on a built-in AVR system (Automatic Voltage Regulation). This means that the supplying voltage is automatically regulated. If there's a decrease or increase in voltage. the AVR system corrects it to a level close to the nominal one. The presence of such a solution in the UPS positively affects the durability of the built-in battery. Additionally. the UPS is equipped with a maintenance-free battery. ensuring stable operation during computer power outages. During this time. you can save important data on the disk or finish another level of your game. The battery charging process up to 90% efficiency takes up to 6 hours.DISCOVER A BETTER WORK FORMATThe 650VA UPS power supply offers:- Automatic Voltage Regulation (AVR) this ensures not only stable power supply and lower battery consumption. but above all. protection of the device from excessively high/low voltage.- cold start a very useful feature - in case of a power outage. you can start. for example. a computer by connecting it directly to the UPS. This allows you to quickly. at any time. copy important files to a USB memory or send an important email.- protection against overload. discharge. and overcharge.- 1 built-in battery.SIMPLY AND CLEARLY - FOR YOUR COMFORThe inclusion of LED indicators in the uninterruptible power supply is intended to provide efficient information about the current status of the device. This ensures that handling the power supply is easy. quick. and reliable.
