Stay online and prevent data loss. Thanks to double conversion technology, the APC Smart-UPS Ultra On-Line Li-Ion continuously provides all connected devices with clean power. Power outages have no impact on this. The APC Smart-UPS On-Line automatically delivers backup power without the need for a switch-over, preventing unwanted downtime for servers, storage, or switches. With the free APC PowerChute Serial shutdown software, you can automatically and safely shut down critical IT hardware when the UPS battery is nearly depleted, avoiding data loss, downtime, and physical damage to the hardware.

Thanks to next-generation semiconductor technology, this APC Ultra UPS delivers 3000 W in a 1U form factor.

The APC SRTL3KRM1UIC uses Li-Ion batteries, which offer unique advantages:

• Longer lifespan: Li-Ion batteries can last up to 10 years, making the UPS maintenance-free.
• Smaller and lighter: Li-Ion batteries are smaller and weigh about 30% less than lead-acid batteries, saving space and simplifying installation.
• Better performance at high temperatures: Li-Ion batteries perform well at high ambient temperatures (up to 40 °C), unlike lead-acid batteries, which suffer reduced battery life under such conditions.
• 5-year manufacturer's warranty: Standard long warranty on the UPS including the battery.
• Lower costs: These advantages reduce the total cost over the entire lifespan of the UPS by up to 53% compared to a UPS with lead-acid batteries.

You can easily read the estimated battery runtime in the runtime graph found between the product images, showing how long the UPS will provide backup power at a specific load.
