APC Smart-ups 3000VA RM 2U LCD 100V - SMT3000RMJ2U

APC by Schneider Electric SMT3000RMJ2U 3000VA 2U Rack-Mount UPS

Overview

The APC by Schneider Electric SMT3000RMJ2U is a 3000VA/2700W rack-mount uninterruptible power supply designed for server rooms, network closets, and surveillance infrastructure where clean, conditioned power is non-negotiable. Occupying only 2U of rack space, it delivers true online double-conversion protection — keeping connected equipment isolated from sags, surges, and outages on 100V single-phase circuits common in Japanese-market deployments and certain North American specialty installations. If you're sizing power protection for a mid-density NVR stack, network switch shelf, or access control head-end, this unit gives you a practical 2700W capacity ceiling with enough outlet diversity to cover mixed load types.

With a measured efficiency rating of 97.6%, the SMT3000RMJ2U runs cooler and draws less from the utility than older UPS designs at comparable capacity — a real factor when you're calculating rack power density or operating in thermally constrained environments. The front-panel LCD provides real-time load percentage, battery runtime, and input/output voltage at a glance, eliminating the need to log into a management interface just to check unit health during a walkthrough.

Key Features

• 3000VA / 2700W Output Capacity: Enough headroom to carry a mid-size NVR with attached storage, a PoE switch, and ancillary security equipment simultaneously. At full 2700W load, expect approximately 2 minutes of runtime — enough to execute a graceful shutdown sequence or transfer to a generator. Plan your load at 60–70% of rated capacity to extend runtime meaningfully.
• 97.6% Operating Efficiency: At near-full load, this unit wastes roughly 2.4% of input power as heat — significantly less than older ferro-resonant or line-interactive designs. In a 24/7 surveillance deployment, that difference compounds into measurable savings on the monthly utility bill and reduces cooling load in the IDF or server room.
• LCD Status Display: Real-time visibility into load percentage, estimated runtime, and input/output voltage without opening a browser or SSH session. Useful during commissioning to verify load balance across circuits, and during incidents to assess available runtime instantly.
• 8 AC Outlets (NEMA 5-15R and 5-20R mix): The outlet complement supports both standard 15A devices and 20A-rated equipment on the same unit. For a typical surveillance rack — NVR, switch, access control panel, and a few ancillary devices — 8 outlets is sufficient without requiring a PDU in front of the UPS.
• Emergency Power Off (EPO) Support: The EPO terminal allows facility management systems or fire suppression panels to cut power to the UPS remotely in an emergency. This is a code requirement in many data center and server room installations — verify your local jurisdiction's requirements before assuming it's optional.
• 459J Surge Energy Rating: Protects downstream equipment from transient voltage events that wouldn't trigger a full transfer to battery. At 459 joules, this is adequate for office and light-industrial environments; for sites with frequent lightning exposure or heavy motor loads nearby, evaluate whether additional surge protection upstream is warranted.
• USB 2.0 Management Port: Connects to a host system for software-based monitoring and graceful shutdown signaling. Compatible with APC PowerChute software for automated shutdown scripting — relevant if your NVR or server OS needs time to close write buffers before power cuts.
• 55 dB Audible Noise: Comparable to a quiet office environment. Acceptable for IDF closets and server rooms, but factor this into any open-office or reception-area installations where ambient noise matters.
• NEMA L5-30P Input Plug: The twist-lock 30A input plug requires a matching L5-30R receptacle on the facility circuit. This is not a standard 15A or 20A wall outlet — confirm your rack circuit is provisioned with an L5-30 outlet before ordering. Mismatch here means the unit cannot be installed without an electrician.
• 50/60 Hz Input Frequency: Accepts both 50Hz and 60Hz utility input, making this unit usable in regions with either frequency standard — relevant for multi-site security integrators who standardize on a single UPS model across domestic and international installations.

Integration & Compatibility

The SMT3000RMJ2U is designed for 100V single-phase input and output, which restricts it to markets where 100V utility power is standard (primarily Japan) or specialty 100V branch circuits. Do not assume this unit will accept 120V North American utility power without verifying the input voltage specification for your specific circuit. Output is also regulated to 100V, so downstream equipment must be rated for 100V operation.

The USB management port enables integration with rack UPS monitoring software and graceful shutdown agents. For deployments running network video recorders or server-based VMS platforms, pairing this UPS with an automated shutdown agent ensures video data integrity if utility power fails and battery runtime is exhausted.

Frequently Asked Questions

Q: What input voltage does the SMT3000RMJ2U require?

A: The SMT3000RMJ2U is rated for 100V input operation. It is designed for 100V single-phase utility circuits, most commonly found in Japan or specialty installations. It is not rated for standard North American 120V circuits — verify your facility circuit voltage before ordering.

Q: What input plug type does the SMT3000RMJ2U use?

A: The unit uses a NEMA L5-30P twist-lock plug, which requires a matching L5-30R receptacle rated for 30A. This is not a standard household outlet — confirm your rack circuit is provisioned with the correct receptacle prior to installation.

Q: How long will the SMT3000RMJ2U run on battery at full load?

A: At full 2700W load, rated backup time is approximately 2 minutes — sufficient for a graceful shutdown sequence or generator transfer, but not extended operation. Reducing the connected load to 60–70% of capacity will extend runtime meaningfully; use APC's runtime calculator or the front-panel LCD estimate for your specific load profile.

Q: Does the SMT3000RMJ2U support remote shutdown of connected equipment?

A: Yes. The USB 2.0 management port connects to a host system and supports APC PowerChute software for automated, graceful shutdown signaling. This is important for NVRs and servers that need time to close write buffers before power is cut.

Q: What is the Emergency Power Off (EPO) feature on the SMT3000RMJ2U?

A: The EPO terminal allows a facility management system or fire suppression panel to remotely cut power to the UPS in an emergency. This is a code requirement in many commercial server room and data center installations. Consult your local electrical code to determine if EPO is required for your installation.

Q: How many outlets does the SMT3000RMJ2U provide, and what types?

A: The unit provides 8 AC outlets total, combining NEMA 5-15R (standard 15A) and NEMA 5-20R (20A) receptacles. This supports a mix of standard and higher-draw devices without requiring a separate power distribution unit in most mid-density surveillance or network racks.

When I look at the SMT3000RMJ2U for a surveillance infrastructure deployment, the spec that stands out immediately is the 97.6% efficiency rating at a 3000VA/2700W capacity class. That's not marketing math — it translates directly to less heat generated per watt of connected load, which matters in thermally tight IDF closets where you're already managing switch and NVR thermals.

Technical Highlights:

• 2700W True Power Output: The gap between VA and watts here is modest (90% power factor), meaning you get close to the full 3000VA in usable wattage — less derating than older UPS designs with 0.6 or 0.7 PF ratings that would cap you at 1800W on a 3000VA unit.
• NEMA L5-30P Input at 24A Max: The 30A twist-lock input means you need a dedicated, properly rated circuit — this isn't a plug-and-play install. Done right, it gives you a solid 24A draw ceiling with margin, avoiding nuisance breaker trips under surge load.
• 459J Surge Rating + Audible Alarm: The 459J suppressor handles typical transient events, and the audible alarm at 55 dB is loud enough to be heard in an adjacent room — useful during after-hours incidents when no one is actively monitoring the management interface.

Deployment Considerations:

• The 2-minute full-load runtime is a hard constraint — design your shutdown scripts and generator transfer time around that ceiling, not around it. If your generator takes 30–45 seconds to reach stable output, you have roughly 75–90 seconds of margin at full load before the UPS depletes.
• The 100V input/output rating is the most common source of procurement errors with this SKU. Confirm both the facility circuit voltage and that every connected device is rated for 100V before commissioning — this is not interchangeable with a 120V Smart-UPS variant.

This unit fits best in a rack serving Japanese-market surveillance or network infrastructure — a mid-density NVR bay, access control head-end, or switch shelf on a 100V circuit where you need generator-bridging runtime, outlet diversity across 15A and 20A devices, and EPO support for code compliance.
