Uninterruptible Power Supply UPS Qoltec 53775 1.2 kVA 720 W 4 AC outlets

The Qoltec Line Interactive UPS 53775 (1.2 kVA / 720 W) is a compact uninterruptible power supply designed to maintain stable operation of connected computers and other data-processing devices during power interruptions and voltage fluctuations. It includes Automatic Voltage Regulation (AVR), a maintenance-free battery, LED status indicators and four AC outlets to provide short-term backup power and protection against over/under voltage.

Advantages

This UPS uses a modified sine output suitable for computers, laptops and most office equipment that do not require a pure sine wave, offering a simpler design and lower failure rates. The built-in AVR corrects voltage drops and spikes to near-nominal levels, which reduces battery wear. Additional features include cold-start capability, overload and battery protection, dual built-in batteries and clear LED indicators for alarm, battery level and power status. The battery reaches approximately 90% charge within about 6 hours.

Suitable for

• Backup power for desktop computers and workstations
• Protection of network peripherals and small home office equipment
• Short-term power for saving work, graceful shutdowns or finishing tasks
• Environments with frequent voltage fluctuations

• Battery: maintenance-free, built-in (7 Ah indicated in product data)
• Recharge time: up to 6 hours to ~90%
• Device type: Line-Interactive UPS with AVR
• Colour: Black
• Weight: 9.4 kg

How to use

Connect your devices to the UPS AC outlets and plug the UPS into a mains socket to charge the internal battery. During normal operation the AVR will regulate minor voltage variations; in the event of a power outage the UPS will switch to battery power and supply connected equipment with a modified sine output. Use the LED indicators to monitor alarm status, battery level and mains/power condition. The cold-start function allows the UPS to power connected equipment directly from the battery when mains power is absent.

Recommendations

To maximize battery life and ensure reliable backup, allow the UPS battery to fully charge after initial installation (up to 6 hours), avoid connecting devices that demand a pure sine wave, and periodically test the unit under load. Place the UPS in a ventilated, dry location away from heat sources and heavy dust.
