The new Atlas online series provides true double-conversion technology and the highest level of protection suitable for critical equipment. This series combine an optimized level of performance with rich functionality, resulting in a highly efficient system that is easy to maintain and operate. Designed to prevent unexpected service interruptions due to overloads, internal fault conditions or during blackouts, the UPS ensures reliable and continuous operation through its internal battery pack and an optional external battery module. Ideal for high density power protection demands, the Atlas features a versatile rack/tower form factor to fit diverse environments. Despite its compact footprint, this UPS incorporates internal battery packs which can be accessed via the front panel for maintenance checks and replacement without removing the UPS from its mounting rack. The LCD display panel can be easily shifted by pressing buttons to suit the installation format, vertically when mounted on a stand or horizontally if installed in a rack. Besides, IT personnel can manage equipment well from learning remaining backup time information via LCD display.
