Compact 3U rack UPS with lithium-ion battery

The APC SMTL1500RM3UC delivers 1440VA and 1350W of pure sine wave output in a short-depth 3U rackmount chassis. Six NEMA 5-15R outlets protect network gear, servers and edge devices. A lithium-ion cell reduces battery replacements over the unit’s life. The bundle adds a 16GB USB 3.0 drive for logs or firmware.

Sustained runtime and automatic voltage regulation

Line-interactive topology with automatic voltage regulation corrects brownouts and overvoltages without draining the battery. During extended outages the lithium-ion pack maintains continuous pure sine wave output to connected loads. The short 11.89in depth leaves cable room for dense racks. LCD status and SmartConnect port enable remote monitoring.

Replaces lead-acid tower units

IT teams swap bulky tower UPS units for this 3U form factor when rack density matters and battery swaps are impractical. The 1350W capacity supports typical switches, routers and single-socket servers. Buyers needing longer runtime at higher loads or additional outlet types should evaluate larger lithium-ion or modular UPS platforms.

Questions about this item

How much heat does the 1350W UPS produce when running continuously in a closed rack?

The lithium-ion battery and line-interactive design generate less waste heat than lead-acid units, and the short 11.89 in depth leaves extra airflow space in the rack.

What rack hardware must I already own to mount this 3U unit?

You need a standard 19-inch rack with at least 3U (5.16 in) of vertical space and mounting rails rated for 42.99 lb.

Will the NEMA 5-15R outlets power older servers that only have C13 inlets?

The six NEMA 5-15R outlets accept standard North American plugs; you will need 5-15P-to-C13 adapter cords for C13-only equipment.
