Product information

Description

Qoltec Monolith UPS Double-conversion 0.45 kVA 240 W is a compact uninterruptible power supply designed to protect computers and other sensitive electronic devices from power disturbances. The unit provides continuous power flow with double-conversion topology, two AC outlets and a USB Type-B port. Built-in LCD and passive cooling allow monitoring and quiet operation while the maintenance-free internal battery supplies emergency power during outages.

Advantages

This UPS features double-conversion topology for stable, continuous output regardless of input fluctuations, automatic voltage regulation to limit stress on the battery, and a modified-sine output suitable for typical computer and networking equipment. The device includes protection against overload, battery over-discharge and overcharge, RJ45 surge protection for network lines, audible alarms for low battery and faults, and a cold-start function. A built-in LCD provides clear status information and the compact black housing with passive cooling supports reliable, quiet operation.

How to use

Connect the UPS to mains power, attach your computers and peripherals to the two AC outlets and connect the USB Type-B port to a PC if you need power management software monitoring. When mains power is present the UPS charges the internal battery and supplies conditioned power; in case of mains failure the battery provides power so you can save work and shut down equipment. Use the LCD to check status, battery level and fault indicators. The cold-start function allows powering a device directly from the UPS when mains power is absent.

Usage recommendations

Place the UPS in a well-ventilated, dry location away from heat sources. Regularly check battery status via the LCD and test the shutdown sequence with connected equipment. Avoid connecting devices that require a pure sine wave inverter if specified by the device manufacturer.
