## Long description

The Qoltec 53044 double-conversion online UPS delivers stable, clean power with a pure sine wave output, rated 10 kVA (8000 W). Designed as a tower unit with active cooling and a built-in battery string (192 V, 7 Ah cells, 16 batteries), it maintains constant output voltage and frequency to protect sensitive equipment during mains interruptions. The unit features an LCD for status monitoring, a USB port for communication, RJ45 surge protection, RS-232 interface compatibility, and supports optional SNMP management (SNMP module code 50389). The UPS also includes an EPO (Emergency Power Off) interface for remote shutdown.
Advantages
The on-line double-conversion design continuously conditions incoming AC by converting it to DC and back to AC, providing zero transfer time to battery power and full isolation from mains disturbances such as outages, surges and voltage sags. The pure sine wave output is suitable for sensitive servers and electronics. Additional features include overload, short-circuit and overtemperature protection, cold-start capability to power equipment without mains present, and an LCD for convenient real-time monitoring and configuration.
Suitable for
Servers and data centers requiring continuous clean power
Network and telecommunication equipment
