Product identity

The APC Smart-UPS X SMX1500RM2UNC is a 2U rackmount uninterruptible power supply rated at 1440 VA and 1200 W. It delivers 120 V output from a 120 V input through eight NEMA 5-15R receptacles. The unit suits network closets, server racks or edge sites that need battery-backed runtime for critical loads.

Pre-installation checks

Verify that your facility provides a NEMA 5-15P branch circuit within the 82 V to 143 V nominal window, adjustable down to 75 V and up to 154 V. Confirm the rack or shelf can accept a 2U form factor and that the connected equipment does not exceed the 1200 W rating. Ensure a SmartSlot or USB management path is available if remote monitoring is required.

Sustained-load behaviour

The sealed lead-acid battery module (replaceable with part PCRBC115) recharges in approximately three hours after a discharge event. During extended outages the UPS maintains regulated 120 V output while audible alarms signal low-battery and overload conditions. Surge protection is rated at 600 joules for continuous transient suppression.

Questions about this item

What outlets are included and do I need to buy any cables separately?

The unit provides eight NEMA 5-15R outlets and ships with a NEMA 5-15P input cord; no extra cables are required for basic operation.

How do I decide between the VA and watt ratings when sizing my load?

Use the 1200 W figure for real power draw and the 1440 VA figure for apparent power; size your connected equipment so neither value is exceeded.

What does the 600 joule surge rating mean for my rack equipment?

It indicates the energy the UPS can absorb in a single surge event, protecting attached devices from transient voltage spikes.
