Product information

Description

Qoltec Monolith uninterruptible power supply provides backup power and voltage regulation to protect connected equipment during mains disturbances. The unit includes automatic voltage regulation (AVR), cold start capability and an LCD that displays operational status. It is intended for users who need to maintain stable operation of computers and similar devices when mains voltage fluctuates or fails.

Advantages

The UPS offers AVR to stabilise input voltage and reduce battery cycling, an LCD for clear status information, cold-start capability to power a connected device when mains power is absent, surge protection for network lines via an RJ45 interface, and audible alarms for low battery and fault conditions. It has a built-in maintenance-free battery and a USB port for power-management communication.

Suitable for

  • Home and small office desktop computers
  • Network devices that require surge protection over LAN
  • Peripherals and devices needing brief backup to save data or perform safe shutdown

Key specifications

  • Brand: Qoltec
  • Model: Monolith (MPN 53979, EAN 5901878539799)
  • Output power capacity: 0.85 kVA
  • Output power: 480 W
  • AC outlets: 2
  • USB ports: 1 (USB Type-B for management)
  • Battery: built-in maintenance-free battery
  • Product colour: Black
  • Weight: 3.544 kg

How to use

Connect the UPS to mains and allow the internal battery to charge. Plug the computer and other critical devices into the AC outlets. Use the LCD to monitor status and settings. If mains power fails, the UPS will supply power from its internal battery and the AVR will regulate voltage automatically. Connect the USB Type-B port to a computer and install available power-management software to monitor UPS events and configure automated shutdown if required.

Usage recommendations

Keep the UPS in a well-ventilated, dust-free location away from direct heat or moisture. Allow up to 6 hours for the battery to charge to approximately 90% after the initial setup. Regularly test the backup function and ensure connected equipment power draw does not exceed the rated 480 W output.
