Compact rack UPS for edge servers

The APC SMTL750RM2UC delivers 750VA and 600W of sine-wave power in a 2U short-depth chassis. It accepts an input range of 82 to 144V through a NEMA 5-15P plug and feeds six NEMA 5-15R outlets at 120V. Lithium-ion cells recharge in 2 hours and provide twice the service life of typical lead-acid batteries. A 680 joule surge rating protects connected gear from transients.

Front-access outlets and replaceable cells

Six NEMA 5-15R receptacles sit on the front panel for quick cable routing in shallow racks. The 17.20 by 3.40 by 12.50 inch footprint fits depth-constrained cabinets while the 34.00 lb weight keeps the load manageable. User-replaceable lithium-ion modules let IT staff swap batteries without removing the unit from the rack. SmartConnect enables remote monitoring through a secure cloud portal.

Replaces bulkier lead-acid units

This UPS suits sites that need longer battery longevity and reduced maintenance cycles. The jump is worth it when rack depth is limited and the 600W capacity covers the critical load. Buyers who need extended runtime beyond the internal pack or higher wattage for dense blade servers should evaluate larger-capacity models.

Questions about this item

What input voltage range does the NEMA 5-15P connection accept?

The input connection accepts 82 to 144V, covering typical 120V utility supply with a wide tolerance for sags and swells.

How deep is the unit, and will it fit in a short-depth rack?

Depth is 12.50 inches, height is 3.40 inches (2U), and width is 17.20 inches, designed for short-depth rack installations.

What is the correct way to install the lithium-ion battery module, and what step is often missed?

Slide the user-replaceable lithium-ion battery module into the front compartment until it locks, then allow up to 2 hours for the initial recharge before relying on backup runtime.
