Stay always online and prevent data loss
An APC Smart-UPS Ultra On-Line Li-Ion always supplies perfectly clean power to all connected equipment thanks to its double conversion technology. Even power outages have no influence on this. The APC Smart-UPS On-Line then automatically supplies emergency power without having to switch. This way you prevent unwanted failure of, for example, a server, storage or switch. With the free APC PowerChute Serial shutdown software you can even have critical IT hardware shut down automatically and in a controlled manner when the battery of the UPS is almost empty. This way you prevent data loss, downtime and physical damage to hardware.

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

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

-Longer life span. Li-Ion batteries can last up to 10 years, making the UPS truly maintenance-free.
-Smaller and lighter. Li-Ion batteries are smaller and weigh approximately 30% less than lead acid batteries, saving space, 2U form factor and simplifying installation.
-Better performance at high temperature. Li-Ion batteries perform well at high ambient temperatures (up to 40°C), in contrast to lead acid batteries where this is at the expense of battery life.
-5 year manufacturer's warranty. Standard long warranty on the UPS including the battery.
-Lower costs: The above benefits reduce the total costs over the entire lifespan of the UPS by up to 53% (compared to a UPS with lead-acid batteries.)

Battery life
You can easily read the expected battery life in the runtime graph, which you can find between the product images. You can easily see how long the UPS supplies emergency power at a certain load.

Extend the runtime
You can easily increase the number of minutes that the APC SRTL3KRM1UIC can independently supply emergency power by connecting up to 5 additional external battery packs (SRTL50RMBP1U-LI). A runtime of several hours is even possible.

SmartConnect
Out-of-box remote UPS monitoring, free for a 6-month trial period. Using the SmartConnect ethernet port, you can easily connect the Smart-UPS to your network and easily monitor it remotely via the secure APC SmartConnect cloud-based web portal. The UPS can also be monitored via this port via EcoStruxure IT Expert.

Network Management Map
If you connect the UPS directly to your network via the optional APC Network Management Card (AP9640/AP9641), it can easily be managed remotely via SNMP or our remote management software Ecostruxure IT Expert (SFTWES1-DIGI). You can also automatically send a shutdown signal via the network to multiple physical and/or virtual servers. By means of APC PowerChute Network Shutdown Software associated with the network card can even be differentiated in the shutdown moment and the order in which this happens.

Availability
The Smart-UPS On-Line has an internal bypass and uses double conversion, which increases the availability and lifespan of connected hardware.

Safety
In addition, a Smart-UPS On-Line protects connected devices against peak voltage caused by lightning, among other things. This APC emergency power supply is therefore ideally suited for business use.

Easy to use
The APC Smart-UPS SRTL is easy to operate thanks to a graphic LCD screen with auto-rotation.

Rack/Tower/Wall/Ceiling/Desk convertible
The SRTL3KRM1UIC can really be placed anywhere. Both feet (Tower), the 4 post rails (Rack), and wall brackets (Wall) are included. So you can mount it horizontally in a rack, but also place it vertically or hanging.

Switched Outlet Groups: Remote reboot and phased start-up
Thanks to the Switched Outlet Groups, it is possible to configure a phased/delayed power-on per UPS outlet group. This reduces the peak load on the UPS and brings it closer to the constant load, which limits oversizing of the UPS. 

It is also possible to reset a group of multiple UPS outputs and the equipment connected to them. If SmartConnect Advanced (ERWPLUS1-1Y-DIGI) is used, a UPS with SmartConnect port + Ecostruxure IT Expert (SFTWES1-DIGI) or a network card (ap9640) in combination with Ecostruxure IT Expert (SFTWES1-DIGI), this is even possible at a distance.
