## Long description

The Qoltec Line Interactive UPS 53771 (2 kVA, 1200 W) provides uninterrupted power to connected computers and electronic equipment during mains voltage drops or outages. Equipped with automatic voltage regulation (AVR), a maintenance-free 12 V 9 Ah battery, an LCD display and USB Type-B communication, it monitors and stabilizes supply voltage while supplying backup power from two AC outlets. The unit supports cold-start and includes surge protection for LAN (RJ45) and audible alarms.
Advantages
The UPS uses a modified sine wave output suitable for computers and most data-processing devices, offering a simpler design and lower failure rates compared with pure-sine solutions. The Line-Interactive topology with AVR corrects undervoltages and overvoltages automatically, reducing battery wear and extending run reliability. The built-in LCD provides real-time status and parameters, while the USB port enables power-management software monitoring. The unit also protects against overload, overcharge and deep discharge, and features cold-start capability for starting equipment when mains power is absent.
Suitable for
Home and office desktop computers
Workstations and peripherals that do not require a pure sine wave
Network devices protected via RJ45 surge suppression
Data-saving and graceful shutdown during short outages

How to use
Connect the UPS to mains power and allow the battery to charge; charging to approximately 90% takes up to 6 hours. Plug the computer or other supported devices into the two AC outlets and connect the USB Type-B port to a PC if you require software monitoring of power events. In normal conditions the AVR maintains stable output; in case of mains failure the UPS switches to battery backup automatically. Use the cold-start function to start equipment from the UPS when mains power is unavailable. Monitor status on the LCD and respond to audio alarms as needed.
Usage recommendations
Install the UPS in a well-ventilated, dry location away from direct heat sources. Fully charge the battery before first use, test graceful shutdown procedures with your critical equipment, and periodically check the LCD status and battery health. Do not connect devices that explicitly require a pure sine wave output.
