## Long description

The Qoltec 53777 Line-Interactive UPS (2 kVA / 1200 W) provides stable power to connected computers and equipment during power outages and voltage fluctuations. Designed for users who need reliable control over device operation, this UPS includes AVR regulation, a maintenance-free battery system, four AC outlets and a USB Type-B port to ensure continuous operation and safe shutdown when mains supply is interrupted.
Advantages
The unit uses a modified sine output suitable for computers and most data-processing devices, offering a simpler design and lower failure rates compared with pure-sine solutions. Built-in AVR (Automatic Voltage Regulation) automatically corrects low or high input voltage to values close to nominal, which helps extend battery life. The UPS includes overload, overcharge and deep-discharge protection, cold-start capability and clear LED indicators for alarm, battery level and power status.
Suitable for
 Home and office desktop computers
 Workstations and small servers that tolerate modified sine output
 Network devices and peripherals needing short-term backup
 Safe shutdown and data protection during short power interruptions

How to use
Connect the UPS to mains power and plug required devices into the AC outlets. When mains voltage fluctuates, the AVR system will regulate supply automatically; if mains power fails, the UPS will switch to battery mode and supply modified sine output. Use the USB Type-B port if you need to connect management or shutdown software. To perform a cold start, power on the UPS without mains connected to start a connected device briefly from the battery.
Usage recommendations
Keep the UPS in a dry, ventilated location away from heat sources. Regularly check LED indicators and test battery backup periodically. Replace batteries according to the manufacturer's service guidance and avoid connecting devices that require a pure sine wave if precise waveform is critical.
