## Long description

UPS QOLTEC Pure Sine Wave 1kVA 800W with AVR and LCD display is a line-interactive uninterruptible power supply designed to deliver stable, pure sine wave output for sensitive electronics. With a rated output of 1 kVA (800 W), automatic voltage regulation (AVR) and an integrated LCD, this UPS maintains clean power, compensates for voltage fluctuations and provides short-term battery backup to allow safe shutdown or continued operation of critical devices during outages.
Advantages
The unit provides pure sine wave output suitable for active power supplies and audio/video equipment, reducing the risk of interference or damage. AVR stabilizes incoming voltage without switching to battery, extending battery life and improving efficiency. The built-in LCD offers clear, real-time status information including load level, battery status and operating mode. Compact form factor and multiple socket outputs simplify installation in home office or small business environments.
Suitable for
 Desktop workstations and small servers
 Networking equipment: routers, switches and modems
 Home office devices: PCs, monitors and VoIP phones
 Audio/visual equipment and streaming setups
 Safe shutdown of sensitive electronics during short outages
Key specifications
 Output capacity: 1 kVA (800 W)
 Output waveform: pure sine wave
 Topology: line-interactive with AVR
 Display: integrated LCD for status and settings
 Voltage regulation: automatic voltage regulation (AVR)
 Backup function: short-term battery backup for controlled shutdown
 Typical connectors: multiple AC outlets (socket types depend on regional model)

How to use
Place the UPS on a stable, ventilated surface away from direct heat and moisture. Connect the UPS to mains power and allow it to charge the internal battery before first use. Plug target devices such as a PC, monitor and network equipment into the battery-backed outlets and non-critical loads into surge-only outlets if available. Use the LCD interface to verify input/output voltage, load percentage and battery charge. During an outage the UPS will switch to battery power automatically; monitor the remaining runtime via the display and perform a controlled shutdown when necessary.
Usage recommendations
For reliable operation, perform periodic self-tests, replace batteries according to the manufacturer's recommended interval, and avoid loading the UPS beyond its rated output. Keep firmware and monitoring software updated when applicable, and ensure connected equipment supports pure sine wave input for best compatibility and performance.
