APC Smart-UPS SRTL1500RMXLI-NC online UPS 1500 VA / 1350 W, 3U rack, Li-ion

An online UPS continuously converts incoming AC to DC and then back to clean AC. Your equipment never sees mains noise, sags or surges directly. Because the inverter runs all the time, there is no switchover when the power fails, and servers and storage do not notice the outage at all.

Instead of lead-acid batteries this model uses lithium-ion. For the same capacity such a battery is generally lighter and handles more charge cycles, which means fewer battery replacements. In a cabinet where every kilogram and every maintenance visit counts, that is a practical advantage.

A real-power rating of 1350 W is high for a 1500 VA unit, so more equipment fits behind it than behind a model with the same VA figure but a lower power factor. Eight IEC C13 outlets leave room for servers, storage, switches and a router without extra power strips.

The UPS takes 3U in the rack alongside your other equipment. All outlets are standard IEC C13, which accept server and network power cords directly. A device with a household Schuko plug needs an adapter cable.

Server rooms and data cabinets where equipment must not feel a single power fluctuation. Companies that want fewer battery swaps thanks to lithium-ion. And IT administrators who need an eight-outlet online UPS for loads up to 1350 W that fits a standard rack.
