Know before you buy
The Lithium-ion battery offers a significantly longer lifespan of 8 to 10 years, which is two to three times longer than standard lead-acid batteries. This reduces the need for frequent replacements and maintenance, while also providing 80-120% more runtime at full load.
This topology provides the highest level of power protection by constantly converting incoming AC power to DC and then back to a clean, regulated AC output. This ensures your connected devices receive zero-transfer-time power that is free from surges, sags, or frequency fluctuations.
Yes, this is an all-inclusive warranty that covers both the electronic components and the battery for the full five-year period. Most standard UPS warranties offer much shorter coverage for batteries, making this a significant benefit for long-term reliability.
The onboard BMS actively monitors the health, temperature, and charge levels of the Lithium Iron Phosphate (LFP) cells. This constant oversight ensures the battery operates within safe parameters, preventing potential failures and optimizing overall performance.
Yes, the UPS features load segments that allow you to manage power distribution. You can configure these segments to prioritize critical equipment, ensuring they stay powered longer while non-essential devices are shut down sooner.
The unit is designed to be 40% lighter than comparable lead-acid models, weighing in at 53.7 lbs. This reduced weight makes it much easier to handle and install in rack-mount environments compared to heavier traditional units.
