The CyberPower PR1500ERTXL2U provides high-quality power protection for IT devices such as computers, workstations, servers, NAS/storage devices, network devices, or telecommunications equipment, as well as for home theater systems, multimedia devices, and video surveillance systems. The UPS can be installed as a rackmount or in tower design. It uses line-interactive topology with automatic voltage regulation (AVR) and offers a stabilized sine wave output in both line and battery operation to ensure high power supply quality. The output power factor of the UPS is 1, meaning that more devices/loads can be connected to the UPS than to those with lower power factors. It features intelligent battery management technology that helps batteries achieve a longer optimized lifespan by balancing the battery voltages of individual batteries. A two-phase controlled charging technology charges the batteries quickly and safely. The hot-swappable battery packs allow for easy maintenance without interruption of operation. The rotatable multifunctional matrix LCD supports intuitive operation and allows configuration of UPS options. Through the USB interface or the optionally available network card, the free downloadable management software PowerPanel Business automatically communicates with the computer and safely shuts down the system in the event of a power failure. It also enables users to perform scheduled shutdowns and self-diagnoses, monitors energy consumption values, and displays the approximate runtime. For the XL versions, external battery extensions can be connected to the UPS to extend runtimes during emergency operation.
