750VA rack-mount UPS for network gear

The APC Smart-UPS X SMX750CNC delivers 750VA and 675 Watts of pure sine-wave backup through eight NEMA 5-15R outlets. It fits a standard 2U rack space and accepts a 120V supply via a NEMA 5-15P plug. Adjustable input range of 75 to 154V and auto-sensing 50/60 Hz frequency keep connected equipment running through brownouts and unstable mains.

Replaces basic desktop units when runtime matters

A lead-acid battery provides 13 minutes at full load and recharges in 3 hours; the replaceable cartridge is APCRBC116. The step up is justified when a workstation or small server needs orderly shutdown instead of an abrupt power loss. Surge energy rating of 645 Joules adds a layer of transient protection that simple strips lack.

Steady output under continuous load

Output voltage stays at 120V with frequency synced to mains within +/- 3 Hz, so attached devices see no frequency shift during transfer. Audible alarms signal on-battery, low-battery and overload conditions without software dependence. UL 1778 and CUL listings confirm the safety envelope for sustained operation in a 17.01 by 3.50 by 19.29 inch, 48.61 lb chassis.

Questions about this item

Will the 17.01" x 3.50" x 19.29" 2U chassis fit my standard 19-inch rack?

Yes, the unit is 2U rackmountable and 17.01 inches wide, matching standard 19-inch rack mounting rails.

How do I install the APCRBC116 battery cartridge, and what step is often missed?

Slide the cartridge into the front compartment until it clicks, then connect the DC cable; the step often missed is securing the front bezel latch after insertion.

When should I replace the APCRBC116 lead-acid battery cartridge?

Replace the APCRBC116 cartridge when the distinctive low-battery alarm sounds or after typical 3-to-5-year service life; recharge takes 3 hours.
