Product information

Description

QOLTEC 52282 is an online uninterruptible power supply with 3 kVA (3000 W) capacity designed to protect servers, network equipment and other critical electronics from mains disturbances. The unit provides continuous double‑conversion topology, delivering a stable pure sine‑wave single‑phase output regardless of input variations. It supports battery‑backed runtime for controlled shutdowns and uninterrupted operation during mains outages, and can be installed in rack or tower configurations to fit different IT environments.

Advantages

The UPS delivers continuous double‑conversion (VFI) operation to ensure consistent output voltage and frequency, eliminating transfer time during power events. A pure sine‑wave output provides compatibility with active PFC power supplies and sensitive equipment. The rack/tower convertible form factor allows flexible installation in server rooms or office cabinets. Built‑in battery management and automatic voltage regulation reduce battery stress and extend service life while maintaining full rated output for connected loads.

Suitable for

  • Small and medium server racks and standalone servers
  • Network switches, routers and communication equipment
  • Storage arrays and NAS devices
  • Workstations, point‑of‑sale systems and critical office electronics
  • Equipment requiring pure sine‑wave supply and uninterrupted operation

Key specifications

  • Output power: 3 kVA / 3000 W continuous
  • Topology: Online double‑conversion (VFI)
  • Output waveform: Pure sine wave
  • Output configuration: Single‑phase output suitable for typical IT equipment
  • Form factor: Rack or tower convertible
  • Battery support: Internal battery system with managed charging
  • Typical applications: Server rooms, network closets, critical electronics protection

How to use

Install the UPS in a suitable rack bay or place it on a stable surface in tower orientation following the manufacturer’s mounting instructions. Connect the UPS input to a dedicated mains supply and plug critical equipment into the UPS output receptacles or output distribution module. Configure runtime and shutdown settings through the unit’s management interface or connected monitoring software where available, and register the UPS into your power management routine. Perform an initial battery charge cycle and a controlled load test to verify correct operation before relying on the unit for mission‑critical protection.

Usage recommendations

Place the UPS in a ventilated environment with ambient temperature within the specified operating range and avoid locations with excessive dust or humidity. Schedule regular battery health checks and firmware or configuration reviews as part of preventive maintenance. For extended runtime needs, consult compatible external battery options and ensure that connected loads do not exceed the continuous power rating to maintain effective protection.
