## Long description

The Qoltec Line Interactive UPS 53773 (0.85 kVA / 480 W) is an uninterruptible power supply designed to maintain stable operation of a connected computer or other electronic device during power disturbances and outages. It includes a built-in 7 Ah maintenance-free battery and a single AC outlet to provide temporary backup power and protect against data loss and unexpected shutdowns.
Advantages
This Line Interactive UPS features Automatic Voltage Regulation (AVR) to correct under- and over-voltage, a modified sine-wave output suitable for computers and laptops, and a cold-start function that allows the device to be powered from the UPS battery when mains power is absent. The unit is engineered with a simple design to reduce failure rates, offers protection against overload, over-discharge and overcharge of the battery, and provides LED indicators for clear status information. The battery charges to approximately 90% in up to 6 hours and delivers around 14 minutes of backup at full load.
Suitable for
Desktop computers and workstations
Laptops and peripheral devices
Home office equipment and network devices
Situations requiring short-term power backup to save work or perform safe shutdown

How to use
Connect the UPS to mains power and allow the internal battery to charge before first use. Plug your computer or other equipment into the UPS AC outlet. During normal operation the UPS will supply power from the mains while AVR corrects voltage fluctuations. If mains power fails, the UPS will switch to battery power automatically, providing time to save work and perform an orderly shutdown. Use the cold-start function to power connected equipment from the UPS battery when mains power is not available.
Usage recommendations
Place the UPS on a stable, ventilated surface away from heat sources and moisture. Periodically check the LED indicators to monitor battery status and charge level. Avoid connecting devices that require a pure sine wave output (such as some precision medical or audio equipment). For prolonged outages, shut down non-essential devices to extend backup time and replace the battery according to the manufacturer’s guidance to maintain optimal performance.
