MPN #: SRTG20KXLI
Power cuts and voltage spikes can shut down servers, damage hardware, and cause costly data loss. When a business loses power, productivity stops and customers lose trust. You need a device that keeps critical equipment running without interruption and protects it from bad power. The APC SRTG20KXLI provides clean, continuous electricity and gives you time to shut down safely, so your operations stay online and your equipment stays safe.
Imagine a UPS that never lets a brief outage turn into a disaster. This is an online double-conversion UPS that creates a pure sine-wave output, so every server, storage array, and network switch receives perfect power. It is built for large IT rooms and can handle up to 20 kVA of load. If the grid fails, the unit switches instantly to its battery, keeping your machines alive and your data intact. APCs reputation for reliability backs every component, from the battery to the smart management card.
The UPS fits in a rack or can be used as a tower, making it ideal for data centers, server closets, and telecom rooms. It also powers industrial control panels, medical imaging devices, and high-performance computing clusters. Any environment that cannot afford a power interruption-such as financial trading floors or video production studios-benefits from its fast switchover and clean sine wave output.
