APC by Schneider Electric SMX3KRMLVNCUS Rack-Mount Smart-UPS
Overview
The APC by Schneider Electric SMX3KRMLVNCUS is a rack-mountable uninterruptible power supply engineered for IT managers and network infrastructure environments where power continuity is non-negotiable. Designed for 120V input and output, it slots into standard equipment racks and delivers conditioned, battery-backed power to connected loads — keeping critical systems online through outages, sags, and surges.
At 84.77 lb (38.45 kg), this is a substantial unit built for permanent rack installation rather than desktop use. Plan your rack's weight capacity accordingly before deployment.
Key Features
- 120V Input / 120V Output: Matches standard North American utility power — no step-up or step-down transformer needed for typical US data closets and server rooms. Plug your existing 120V equipment directly in without rewiring.
- Rack-Mountable Form Factor: Designed to install into a standard equipment rack. The 3.35 in (8.5 cm) dimension indicates a 2U or similar low-profile rack footprint — verify U-height against your available rack space before ordering.
- 8 ft (2.4 m) Input Cable: The included 8-foot power cable gives you enough reach to the nearest PDU or wall outlet without extension cords, which can void equipment warranties and introduce fire risk in dense rack environments.
- Commercial-Grade Weight and Construction: At nearly 85 lb, the SMX3KRMLVNCUS carries substantial internal battery capacity — the weight itself signals a unit built for sustained runtime under real load, not a lightweight standby device.
Integration and Compatibility
The SMX3KRMLVNCUS is positioned for IT infrastructure environments — network closets, server rooms, and edge deployments where 120V rack equipment requires battery backup. APC's Smart-UPS line broadly supports network management cards and USB/serial monitoring interfaces for integration with building management systems and remote monitoring platforms, though buyers should confirm specific card compatibility against their management software before purchase. Consult the UPS and power protection category for compatible accessories and complementary units in the APC by Schneider Electric lineup.
For rack planning, review your rack and enclosure options to ensure adequate rail support and weight capacity for an 84.77 lb unit.
Frequently Asked Questions
Q: What input and output voltage does the SMX3KRMLVNCUS support?
A: The SMX3KRMLVNCUS operates on 120V input and delivers 120V output — standard North American utility voltage. It is not configured for 208V or 240V environments.
Q: How much rack space does the SMX3KRMLVNCUS require?
A: The listed dimension of 3.35 in (8.5 cm) indicates a low-profile rack footprint. Verify the exact U-height specification against your rack's available space before installation.
Q: How heavy is the SMX3KRMLVNCUS, and does that affect installation?
A: The unit weighs 84.77 lb (38.45 kg). This requires a rack with adequate weight-rated rails and ideally a second person or lift assist during installation. Verify your rack's maximum load rating before mounting.
Q: What length is the input power cable included with the SMX3KRMLVNCUS?
A: An 8 ft (2.4 m) input cable is included, providing standard reach to a nearby PDU or wall outlet in most rack environments.
Q: Is the SMX3KRMLVNCUS suitable for outdoor or harsh-environment installation?
A: No. This is a rack-mount unit designed for controlled indoor environments such as server rooms and network closets. It is not rated for outdoor or harsh-environment use.
The SMX3KRMLVNCUS comes in at 84.77 lb — that weight is the first thing I flag for installers, because it directly affects rail selection and whether you can safely single-person this into a rack. Plan the physical installation before the unit arrives on site.
Technical Highlights:
- 120V In/Out: Matches standard North American building power with no voltage conversion overhead — straightforward for typical US server room and network closet deployments.
- 8 ft Input Cable: The included 2.4 m cable covers most rack-to-PDU runs without needing an extension, which matters for keeping your installation clean and compliant.
- Rack-Mount Form Factor: The 3.35 in profile keeps vertical rack space consumption low — confirm exact U-height before finalizing rack layout, especially in fully loaded cabinets.
Deployment Considerations:
- At 84.77 lb, verify your rack's weight-rated rails and total load capacity before mounting — this is not a unit you want to discover is overweight mid-installation.
- Source evidence for this SKU is limited; confirm VA/watt rating, outlet count, and runtime specs directly from the APC datasheet before sizing this unit against your actual load requirements.
Best positioned in a dedicated IT room or network closet supporting 120V rack equipment where battery runtime and load capacity have been pre-validated against the full APC Smart-UPS SMX3KRMLVNCUS datasheet specs.
