The CyberPower Smart App Online OL6KRTHD high-density design offers more power in less space. In fact, it can be configured into 2U of rack space or as a tower, compared to 3U and 4U for similar competitive UPS models – giving you more room to grow. The OL6KRTHD features double-conversion topology for seamless power protection and a pre-installed RMCARD205. For monitoring, this UPS offers a new state-of-the-art, multi-function, color matrix LCD screen that is simple to set up and easy to use. The color-coded alerts provide clear status of the UPS and the screen orientation rotates automatically when placed into a tower configuration. The OL6KRTHD ensures maximum efficiency and capacity output with a Power Factor rating (PF) of 1. The energy-saving GreenPower UPS ECO Mode enables up to 96% efficiency while reducing power consumption and thermal dissipation. The variable 7-speed fan provides automatic thermal management, based on power load, to reduce noise. The optional BP144VL2U01 Extended Battery Module (EBM) expands runtime and up to ten EBMs can be connected in a daisy-chain to the UPS for more backup power.
