Know before you buy
This unit is designed for critical business infrastructure, such as servers, networking switches, and storage devices that require a compact 1U form factor. With 1100 watts of power capacity, it provides reliable protection for essential hardware in space-constrained rack environments.
The line-interactive topology includes automatic voltage regulation, which actively corrects minor voltage fluctuations without switching to battery power. This helps extend the life of your connected equipment and preserves battery health by reducing unnecessary discharge cycles.
At a full load of 1100 watts, you can expect approximately 4 minutes of runtime. This is generally sufficient time to allow for a graceful, automated system shutdown to prevent data loss or hardware corruption.
No, the batteries in the Eaton 5P1500R-L are not hot-swappable. While the unit features advanced battery management technology to extend lifespan, you should plan for professional maintenance or unit replacement when the battery reaches the end of its service life.
No, this model provides a simulated sine wave output. While this is perfectly suitable for most standard server power supplies and networking gear, you should verify that your specific equipment does not require a pure sine wave input before purchase.
The UPS features built-in energy consumption metering, which allows you to track power usage directly via the integrated LCD panel. Additionally, the included software provides deeper insights into your power environment and status updates through USB or serial connections.
