CyberPower OLS6KERT5U is a high-efficiency UPS featuring online double-conversion topology, which provides seamless Pure Sine Wave power for mission-critical devices such as NAS, servers, DVRs/surveillance systems, transportation, infrastructure, and emergency systems. It’s typically integrated into the back office, server room, and data center environment.

With high output power factor, the UPS in a smaller footprint can provide more usable power and save rack space. The product allows multiple UPS units to be connected in parallel, achieving higher capacity and power redundancy. The pre-installed Maintenance Bypass PDU (MBP) offers quick and safe maintenance without power interruption. Moreover, the UPS is equipped with Remote Cloud Card to support remote monitoring via a web portal and the mobile app. The tiltable color LCD comes with an intuitive and graphical interface, allowing users to monitor and configure settings with ease. Besides, the battery charging current is adjustable via LCD setting to shorten charging time. It is also designed with relay-type dry contact port to support specific UPS event notifications for easy management.
