## Long description

The Qoltec Line Interactive UPS 1.5 kVA (model 53770) provides stable power to connected equipment during voltage fluctuations and power outages. With 900 W output, two AC outlets, USB Type-B communication and an LCD display, it is designed for users who need controlled and continuous operation of computers and other data processing devices. The unit uses a modified sine output and includes a maintenance-free battery (9 Ah, 12 V) that recharges to 90% in up to 6 hours.
Advantages
This Line Interactive UPS features Automatic Voltage Regulation (AVR) that corrects under- and over-voltage to near-nominal levels, reducing battery use and protecting connected devices. The modified sine output is suitable for computers and similar equipment and contributes to a simpler design and lower failure rates. Additional benefits include cold-start capability, overload/discharge/overcharge protection, surge protection over LAN via an RJ45 port, an audible alarm, and two built-in batteries for reliable backup power. The front LCD provides real-time status and parameter information for easy monitoring.
Suitable for
Desktop computers and workstations
Home office equipment and small office setups
Network devices requiring surge protection via LAN
Situations needing short-term battery backup for saving work or orderly shutdown

How to use
Connect your computer or other compatible equipment to the two AC outlets and plug the UPS into mains power to charge the internal battery. Use the USB Type-B connection and the supplied power management software to monitor status and configure shutdown or alarm settings. In the event of mains voltage abnormalities, the AVR will automatically correct minor deviations; if mains power fails, the UPS will switch to battery power and supply modified sine output until mains return or the battery is depleted. Use the cold-start function to power the unit from battery when mains are absent.
Usage recommendations
Place the UPS in a dry, well-ventilated location away from direct heat sources. Regularly save important work and perform orderly shutdowns when battery runtime is low. Replace the battery according to the manufacturer’s guidance and avoid connecting devices that require a pure sine wave if precise waveform is critical.
