APC Smart-ups X 750VA Rack/tower LCD 120 US - SMX750CUS

APC by Schneider Electric SMX750CUS Rack/Tower 750VA LCD UPS 120V

Overview

The SMX750CUS is APC's Smart-UPS X 750VA uninterruptible power supply, designed for installations where both rack-mount and tower deployment must remain viable — a practical requirement in mixed environments where rack space is contested or the unit may relocate between equipment rooms. The 750VA rating targets edge network closets, small NVR deployments, access control panels, and IP phone systems that need clean, conditioned power without the footprint of a larger unit. The integrated LCD panel surfaces runtime estimates, load percentage, and fault conditions without requiring a laptop or software connection on the initial install.

The rack/tower convertible form factor is the defining characteristic of the Smart-UPS X line. Unlike fixed-orientation UPS units, the SMX750CUS can be installed vertically as a tower on a shelf or rotated and rail-mounted in a standard 19-inch rack — useful when the deployment environment is not yet finalized or when the same SKU needs to serve multiple site types across a distributed rollout.

Key Features

• 750VA Capacity: Sized for small-to-mid edge loads — an NVR with four to eight cameras, a PoE switch, and a fiber converter will typically sit well within this envelope, leaving headroom so the UPS does not run near its ceiling under normal conditions.
• Rack/Tower Convertible: Ships ready for tower use and converts to rack-mount, so a single SKU covers both deployment scenarios. This matters for stocking and standardization across sites with different physical infrastructure.
• LCD Display: The front-panel LCD reports load, battery charge, estimated runtime, and active alarms locally — eliminating the need to connect a laptop or navigate software just to confirm the unit is healthy during a site walk.
• 120V / US Configuration: Wired for North American power infrastructure. Confirm your outlet type and circuit capacity before installation — this unit is not dual-voltage and is not intended for international deployment without appropriate power conversion.

Integration and Compatibility

The Smart-UPS X line is compatible with APC's PowerChute software for graceful shutdown orchestration and event logging — relevant in NVR and server deployments where an uncontrolled power-loss shutdown can corrupt recorded video or database files. Check current PowerChute compatibility against your OS version before deployment. The SMX750CUS supports USB and, depending on the configuration, serial communication for UPS monitoring integration with building management or network management systems.

For UPS and power protection deployments in security infrastructure, pair this unit with appropriately sized PoE switches and verify that the combined load of all connected devices stays below the unit's rated watt output — VA and watts are not the same figure, and the power factor of the connected load determines actual watt capacity. Consult the power protection planning guide for load calculation methodology before sizing a UPS for a multi-camera installation.

For the broader APC by Schneider Electric lineup, including higher-capacity Smart-UPS models and extended-runtime options, review the full catalog to match VA rating to actual measured load.

Frequently Asked Questions

Q: Can the SMX750CUS be mounted in a standard 19-inch rack?

A: Yes. The Smart-UPS X series is designed as a rack/tower convertible. The unit ships in tower orientation and can be configured for rack mounting. Verify rail kit compatibility and available rack units before ordering if rack installation is required.

Q: What is the input voltage for the SMX750CUS?

A: The SMX750CUS is configured for 120V AC, standard North American power. It is not a dual-voltage unit and is intended for US deployment.

Q: What communication interfaces does the SMX750CUS support?

A: The Smart-UPS X line supports USB and serial communication for integration with APC PowerChute software and third-party monitoring systems. Confirm the specific interface options against the current APC datasheet for this model before integrating with a BMS or NMS.

Q: Is the SMX750CUS suitable for protecting an NVR and PoE switch?

A: A 750VA UPS can support small NVR and PoE switch combinations, but actual suitability depends on the measured watt draw of all connected devices. Calculate total load in watts (not VA) and verify it falls below the unit's rated watt output with adequate headroom before deployment.

Q: Does the SMX750CUS include a warranty?

A: APC provides a manufacturer warranty on Smart-UPS products. Contact APC or review the documentation included with the unit for specific warranty terms applicable to this model and region.

The SMX750CUS sits in a useful middle position in the Smart-UPS X lineup — 750VA is enough for a compact security edge node (NVR, managed PoE switch, one or two ancillary devices) without the cost and space overhead of a 1500VA unit, and the rack/tower convertible form factor means you are not locked into one cabinet type at the time of procurement.

Technical Highlights:

• Rack/Tower Convertibility: A single SKU covers both tower-on-shelf and 19-inch rack-mount installations — reduces the number of UPS SKUs you need to stock across sites with different physical infrastructure.
• LCD Local Monitoring: Front-panel display provides load percentage, battery status, and runtime estimates without any software dependency — useful during initial commissioning and routine site checks.
• 120V US Configuration: Matched to North American power infrastructure; no step-down transformer needed for standard US commercial circuits.

Deployment Considerations:

• Size the connected load carefully — 750VA does not translate directly to 750W. The actual watt capacity depends on the unit's power factor rating. Measure actual device draw before finalizing the load list, particularly if the installation includes high-inrush devices like PTZ cameras or motorized locks.
• If rack-mounting, confirm whether a rail kit is included or must be ordered separately — the Smart-UPS X line sometimes ships the rack hardware as a separate accessory depending on the purchase configuration.

The SMX750CUS is well-matched to small security equipment rooms: an 8-channel NVR, a 24-port PoE switch at partial load, and a fiber converter — the kind of edge closet that needs reliable runtime through a 10–15 minute utility interruption without investing in a full 1U rack UPS at twice the price point.
