Product information

Description

Qoltec 52281 is a double-conversion on-line UPS with 2 kVA (2000 W) output power and a power factor of 1.0. Designed to provide stable, clean pure sine wave power with zero switching time, this UPS protects sensitive equipment from mains disturbances such as outages, voltage drops and surges. The unit includes an integrated LCD for monitoring, an EPO interface, USB Type-B communication and three Type F AC outlets. It ships with a built-in set of 4 x 9 Ah batteries and supports SNMP module installation for network management. The device is supplied with a 24-month warranty.

Advantages

The Qoltec 2 kVA on-line UPS delivers continuous double-conversion power that keeps output voltage and frequency constant, ensuring full isolation from input disturbances. With a power factor of 1.0 and pure sine wave output, the UPS maximises usable power and maintains high power quality for sensitive IT equipment. Key features include zero transfer time to battery, overload/short-circuit/overheat protection, ECO mode to improve efficiency, built-in service bypass for maintenance, and active cooling via two fans. The unit also provides extended back-up time and supports remote emergency shutdown via the EPO interface.

Suitable for

  • Small server rooms and rack-mounted IT equipment
  • Network devices and switches requiring clean power and monitoring
  • Workstations and storage devices that need uninterrupted power during outages

How to use

Install the UPS in a well-ventilated location and connect the mains supply before powering connected equipment. Use the integrated LCD to monitor operational status and battery charge. For normal operation leave the UPS connected to mains so the batteries remain charged; in case of mains failure the unit automatically switches to battery with zero transfer time. For network monitoring or remote control, install an SNMP module in the available slot and connect via the USB or RS-232 port as required. Use the built-in service bypass when performing maintenance to avoid interruption to connected loads.

Usage recommendations

Place the UPS on a stable, level surface with adequate clearance for airflow. Periodically check the LCD for warnings, and test the battery backup under load after installation. Replace batteries according to the manufacturer’s guidance or when backup time noticeably decreases. Do not expose the unit to moisture, excessive dust or temperatures outside the recommended operating range.
