## Long description

UPS QOLTEC Pure Sine Wave 3kVA 2400W with AVR and LCD display is an offline/line-interactive uninterruptible power supply designed to deliver clean sine-wave output, short-term backup power and voltage stabilization for sensitive electronics. The unit provides automatic voltage regulation (AVR) to correct under- and over-voltage conditions and an integrated LCD status display to monitor input/output voltage, load level and battery status. With a rated output power of 2400W and a 3kVA apparent power rating, this UPS supports a variety of IT and home-office equipment to reduce the risk of data loss and hardware damage during power disturbances.
Advantages
The UPS produces a pure sine wave output that is compatible with active power supplies and sensitive devices, ensuring stable operation without waveform-related interference. The line-interactive design with AVR compensates for voltage fluctuations without switching to battery for minor disturbances, which extends battery life and maintains equipment uptime. The front-panel LCD display provides real-time information about system status, allowing quick assessment of input voltage, output load and remaining backup time. Compact dimensions and professional protection features make the model practical for small server rooms, network closets and workstations.
Suitable for
Small business servers and network equipment
Workstations and desktop computers used for office or creative work
Home-office setups including routers, NAS devices and VoIP equipment
Point-of-sale terminals and small-scale control systems

How to use
Install the UPS on a stable, level surface in a well-ventilated area away from direct heat and moisture. Connect the UPS input to a grounded AC supply and plug protected devices into the output sockets. Use the LCD to verify correct input voltage and confirm that the UPS is supplying power correctly; test the system under load to estimate backup runtime. For battery maintenance, follow manufacturer guidelines for periodic self-tests and replace batteries according to the recommended service interval. For network-integrated monitoring, connect any supported communication port and configure the monitoring software as required.
Usage recommendations
Place the UPS in a location that allows airflow around the chassis and keep the ambient temperature within the specified operating range. Prioritize critical equipment on the UPS output and avoid overloading beyond the rated 2400W capacity. Schedule regular battery self-tests and replace aging batteries to ensure reliable backup performance.
