Sistema de alimentación ininterrumpida Qoltec 53043

The Qoltec Uninterruptible Power Supply (model 53043) is an on-line, double-conversion UPS delivering 3 kVA (2.4 kW) of output power with pure sine wave output. Designed for sensitive equipment, it supplies a constant voltage and frequency, features zero switching time and an LCD for status monitoring. The unit includes a USB Type-B port, two Type F AC outlets, RJ45 surge protection for LAN, and an internal set of batteries to maintain operation during mains interruptions.

Advantages

This on-line UPS provides high-quality, disturbance-free power through double conversion, ensuring stable sinusoidal output and protection against voltage drops, surges and outages. It offers zero switchover time so connected devices experience no interruption, built-in overload, short circuit and overheating protection, cold-start capability for powering equipment during a blackout, and the option to add an SNMP module for remote monitoring. The clear LCD simplifies real-time monitoring and configuration.

How to use

Install the UPS on a stable, ventilated surface and connect the UPS to mains power to charge internal batteries before first use. Plug your devices into the Type F outlets and connect the USB Type-B port to a monitoring computer if required. Configure settings via the LCD panel or an optional SNMP module for network management. In case of mains failure the UPS will automatically switch to battery mode with zero interruption; use the LCD to monitor runtime and status and perform a controlled shutdown of connected equipment within the available battery runtime.

Recommendations

For reliable operation, allow the UPS batteries to fully charge after initial setup and perform periodic battery tests. Avoid placing the unit in confined spaces without airflow; ensure firmware or monitoring software is kept up to date when using a connected management interface.
