Uninterruptible Power Supply QOLTEC 52284 10kVA 10000W LCD EPO USB On-line

The QOLTEC 52284 On-line Uninterruptible Power Supply delivers continuous, regulated power with a rated output of 10 kVA / 10000 W. Designed for use in server rooms, network closets and other environments requiring high-availability power, this UPS provides on-line double-conversion topology to isolate connected equipment from mains disturbances. The unit features an LCD panel for operational status and configuration, an Emergency Power Off (EPO) interface for rapid shutdown in critical situations, and a USB port for monitoring and basic management from a connected computer.

Advantages

The on-line double-conversion design ensures continuous, clean sine-wave output regardless of input voltage anomalies, protecting sensitive electronics from surges, sags and frequency variations. The integrated LCD offers clear, real-time information on load, battery status and input/output parameters to simplify monitoring and configuration. EPO capability allows safe remote shutdown where required by facility protocols, and the USB connectivity supports event logging and controlled shutdown through compatible software.

Suitable for

• Server rooms and racks hosting critical IT systems
• Network switches, routers and telecommunication equipment
• Industrial controllers and automation systems requiring stable power
• Storage arrays and backup devices that need uninterrupted operation

How to use

Install the UPS on a stable surface or mounting location appropriate for its size and ventilation requirements. Connect the input power according to local electrical codes and ensure the grounding connection is correct. Plug equipment into the UPS output sockets and configure basic settings through the LCD menu, including output sensitivity and alarm thresholds. If remote shutdown is required, connect the EPO interface to the facility’s emergency system. For monitoring, connect the USB port to a host computer and install compatible monitoring software to enable event logging and automated safe shutdown procedures.

Usage recommendations

Place the UPS in a temperature-controlled, dust-free environment with adequate airflow, and schedule regular battery tests and maintenance checks. Avoid connecting loads that exceed the rated output and group high-inrush devices separately to prevent unwanted shutdowns. Use the LCD and monitoring software to verify load and battery capacity before critical operations.
