## Long description

The Qoltec UPS 53776 Line-Interactive 1.5 kVA 900 W is an uninterruptible power supply designed to keep a connected computer and other sensitive electronics running during power disturbances. With a capacity of 1.5 kVA (900 W), four AC outlets and a built-in 7 Ah maintenance-free battery, it provides voltage regulation and temporary backup power while protecting equipment from fluctuations and outages.
Advantages
This Line-Interactive UPS features Automatic Voltage Regulation (AVR) to correct under- and over-voltage without using battery power, reducing battery wear. It uses a modified sine output suitable for computers, laptops and most data-processing devices, offering a simpler design and lower failure rates. The unit supports cold start, includes built-in overload, discharge and overcharge protection, and has LED indicators for clear status information. Recharge time to about 90% is approximately 6 hours.
Suitable for
Home and office desktop computers
Workstations and peripherals requiring short backup time
Small office network devices and modems/routers
Data-protection tasks such as saving files or orderly shutdowns

How to use
Connect the UPS to the mains and allow the unit to charge the internal battery for up to 6 hours before relying on full backup capability. Plug your computer and essential peripherals into the four AC outlets. The AVR will regulate minor voltage fluctuations automatically; in case of a power outage the UPS will switch to battery power to keep devices running. Use the cold start feature to power connected equipment from the UPS when mains power is absent. Monitor the front LED indicators for status and fault notifications.
Usage recommendations
Place the UPS on a stable, ventilated surface away from heat sources and liquids. For best battery life, avoid frequent deep discharges and perform orderly shutdowns of connected equipment when backup time is nearly exhausted. Ensure connected devices do not exceed the 900 W output limit and periodically test the UPS and battery functionality.
