Know before you buy
Unlike standard UPS units, this model constantly converts incoming AC power to DC and then back to a clean, regulated AC sine wave. This process eliminates power fluctuations, noise, and surges entirely, providing your sensitive IT hardware with the most stable power possible.
Yes. The internal battery modules are hot-swappable, meaning you can replace them while the UPS continues to provide power to your connected devices, preventing any downtime during routine maintenance.
The Eaton 9SX supports expandable runtime through the addition of external battery modules. You can connect these modules to the UPS to significantly increase the backup duration for your critical infrastructure.
Yes, it features standard RS-232 and USB ports for local management. For advanced remote access, you can install an optional Gigabit Network Interface card, which allows for 24/7 monitoring and cybersecurity-ready management.
ABM (Advanced Battery Management) technology uses a sophisticated three-stage charging technique that significantly reduces battery corrosion and internal heat. This can extend the service life of your batteries by up to 50% compared to traditional charging methods.
Yes, because it produces a pure sine wave output and has a zero-millisecond transfer time, it is ideal for mission-critical hardware that requires a constant, uninterrupted flow of high-quality power.
