APC Smart UPS 3000VA LCD RM 2U 120V with 12FT Cord - SMT3000R2X145

APC by Schneider Electric SMT3000R2X145 3000VA 2U Rack Mount UPS 120V

Overview

The APC by Schneider Electric SMT3000R2X145 is a 3000VA, 2U rack-mount uninterruptible power supply designed for server rooms, point-of-sale environments, and network closets where clean, conditioned power and short-term runtime during outages are non-negotiable. Drawing on a NEMA L5-30P plug at 120V input and delivering 120V output across eight protected receptacles, this unit fits directly into standard 2U rack space and takes a 12-foot cord to the panel — useful when your PDU or dedicated circuit is on the other side of a rack row. If you're protecting a dense switch stack, a small virtualized server cluster, or a POS lane bank, the SMT3000R2X145 is sized for that exact workload.

Key Features

• 3000VA Capacity: 3000VA is enough headroom to carry multiple 1U/2U servers, a managed PoE switch, and associated storage through a brief outage or a controlled shutdown sequence — without forcing you to load-shed between devices. It's the right tier for small to mid-density rack environments before you step up to a 5000VA frame.
• 2U Rack Form Factor: Two rack units is the industry standard for this power class. You get full UPS protection without sacrificing a disproportionate slice of your rack real estate. Pairs cleanly with 1U PDUs above or below.
• 8 Protected Outlets — Mixed NEMA Configuration: The receptacle layout (six NEMA 5-15R + two NEMA 5-20R) means you can directly connect standard 15A server and networking gear on the 5-15R ports while reserving the two 5-20R ports for higher-draw devices like workstations, high-density switches, or NAS units. No adapter splicing required for mixed-draw environments.
• NEMA L5-30P Input Plug: The locking L5-30P plug connects to a dedicated 30A twist-lock circuit — not a standard wall outlet. This is deliberate: it eliminates accidental disconnection on a live rack and ensures the UPS draws from a circuit sized for its full load. Verify your panel or PDU has an L5-30 receptacle before ordering.
• 12-Foot Cord: At 3.66 meters, the input cord reaches a panel or PDU on the opposite side of most standard rack bays without requiring an extension or re-routing the rack. Shorter cords are a frequent install-day problem on high-VA units; 12 feet eliminates that friction.
• 459 Joule Surge Rating: Surge suppression is built in at 459 joules — meaningful protection against line noise and transient spikes for connected networking and server equipment, though it's not a substitute for upstream surge protection on long building runs.
• Lead-Acid Battery: Sealed lead-acid chemistry is field-replaceable without tools in most APC Smart-UPS rack frames — a key operational consideration for sites where battery swap needs to happen during business hours without a full shutdown. Confirm battery cartridge compatibility at time of service.
• LCD Display: The front-panel LCD gives you at-a-glance status on load percentage, estimated runtime, battery condition, and input/output voltage — without requiring software or network access. Useful during initial commissioning and during incidents when your monitoring stack may itself be offline.
• Front-Mounting Orientation: Rack-mount orientation is front-accessible, meaning the display and controls face outward in a standard rack. No blind installation or rear-panel-only status.

Integration & Compatibility

The SMT3000R2X145 is built for server, networking, and point-of-sale applications. APC Smart-UPS rack units in this class support USB and serial communication ports for UPS management software integration — enabling graceful OS shutdown, runtime monitoring, and event logging through PowerChute or compatible third-party UPS management tools. Verify port availability and software compatibility with your specific OS environment. The unit is compatible with standard 19-inch rack enclosures at 2U height. Input requires a dedicated NEMA L5-30 30A circuit; do not connect to a standard 15A or 20A outlet.

Frequently Asked Questions

Q: What input plug does the SMT3000R2X145 use, and what circuit is required?

A: The SMT3000R2X145 uses a NEMA L5-30P locking input plug and requires a dedicated 30A twist-lock circuit at 120V. It cannot be plugged into a standard 15A or 20A wall outlet.

Q: How many outlets does the SMT3000R2X145 provide, and what types?

A: It provides 8 total protected outlets: six NEMA 5-15R (standard 15A) and two NEMA 5-20R (20A), allowing direct connection of mixed-draw server and networking equipment without adapters.

Q: What is the rack space requirement for the SMT3000R2X145?

A: The SMT3000R2X145 occupies 2U (two rack units) in a standard 19-inch rack enclosure and is front-accessible for display and controls.

Q: What type of battery does the SMT3000R2X145 use?

A: It uses a sealed lead-acid battery. APC Smart-UPS rack units in this class typically support field-replaceable battery cartridges — confirm the compatible replacement cartridge SKU before scheduling a swap.

Q: What equipment is the SMT3000R2X145 recommended for?

A: APC lists this unit for servers, point-of-sale systems, routers, switches, and hubs — specifically in multi-core or virtualized server environments where clean power and orderly shutdown capability are required.

Q: What is the surge rating on the SMT3000R2X145?

A: The SMT3000R2X145 provides 459 joules of surge suppression on all connected outlets, protecting equipment from line transients and voltage spikes.

The SMT3000R2X145 is the unit I spec when a site has a dedicated 30A twist-lock circuit and needs 3000VA of true rack UPS protection in 2U — the L5-30P input is the gating factor, and it's also the feature that makes it the right tool for the job. Unlike units that run off a standard 20A circuit and leave you wondering if someone will accidentally unplug the UPS during a maintenance pass, the locking L5-30P means the connection is intentional and secure.

Technical Highlights:

• 3000VA / 2U: High power density for the rack footprint — carries a multi-server stack or a dense PoE switch environment through an outage without requiring a 3U or 4U chassis.
• Mixed Outlet Bank (6x 5-15R + 2x 5-20R): The two 5-20R ports are the detail most buyers overlook until install day. Having native 20A receptacles means your higher-draw NAS, workstation, or high-wattage switch connects directly — no cheater adapters creating a code or warranty issue.
• 459J Surge + LCD: The front LCD lets you verify load percentage and battery health at the rack door without remoting in — critical during the first 48 hours after installation when you're dialing in load balance across outlets.

Deployment Considerations:

• Confirm the panel or in-row PDU has an available NEMA L5-30 30A receptacle before the unit ships to site — this is the single most common install blocker on this model class, and a field-fabricated adapter is not a compliant solution.
• The 12-foot input cord is generous, but if your rack is center-of-room and your panel is on the wall, measure the actual run before assuming it reaches — 12 feet goes fast when you account for cord management and bend radius.

For a virtualized server closet or a security operations rack running NVR, managed PoE switches, and access control servers off a dedicated 30A circuit, the SMT3000R2X145 is sized correctly and installs clean — this is not a unit to shoehorn into a standard outlet environment.
