APC by Schneider Electric SMT1000RMI2U 1000VA Line-Interactive 2U Rack UPS
Overview
The APC SMT1000RMI2U is a 1000 VA / 700 W line-interactive rack-mount UPS designed for 2U rack deployment in environments where power quality and runtime reliability are non-negotiable — NVR closets, server rooms, edge network cabinets, and surveillance head-end racks running 230V infrastructure. Its pure sine wave output and Automatic Voltage Regulation handle the wide 151–302V input swing common in commercial building power without switching to battery, which extends battery life and keeps sensitive electronics stable. If you're protecting a network video recorder stack or edge switching gear that feeds a camera network, the SMT1000RMI2U belongs in the conversation.
Key Features
- Line-Interactive Topology with Pure Sine Wave Output: Unlike simulated or stepped approximation waveforms, the true sine output of this unit is safe for active power-factor-corrected (PFC) power supplies found in modern NVRs, servers, and managed switches. Simulated-sine UPS units can cause PFC PSUs to fault or run hot — this one won't.
- Automatic Voltage Regulation (AVR) — 151V to 302V Input Range: AVR corrects over-voltage and under-voltage conditions (the full 151–302V window) using the transformer alone, without touching the battery. That's critical in commercial deployments where brownouts are frequent: you preserve battery capacity for genuine outages rather than burning through charge cycles on routine sags.
- 98.2% Efficiency: At near-line efficiency, this unit runs cool and adds negligible heat load to your rack — a real consideration in dense 1U/2U stack configurations where thermal headroom is tight. Lower heat also translates directly to longer component life.
- 459 J Surge Energy Rating: Absorbs transient surges before they reach downstream equipment. For NVR and switching gear with internal PSUs, surge events are silent killers — 459 J provides meaningful protection without requiring a separate surge suppressor in the rack.
- 4 × IEC C13 Output Outlets: The C13 rack outlet format is the standard for 1U servers, managed switches, NVRs, and rack-mounted encoders — no adapters required. C14 input coupler means you're using standard rack PDU or inline power cords throughout.
- Auto-Restart After Power Restoration: When utility power returns, the SMT1000RMI2U restarts automatically without manual intervention. In unmanned remote closets or after-hours outages, this means your surveillance and network infrastructure comes back online without a site visit.
- Audible Alarms + EPO Support: On-battery and fault conditions trigger audible alarms so local staff know immediately. Emergency Power Off (EPO) capability allows integration with building management or data center EPO circuits — required in many commercial and government facility standards.
- 45 dB Noise Level: At 45 dB, this unit is quiet enough for office-adjacent or open-plan network closets where fan noise accumulates. Comparable to a quiet office environment — won't add noticeable acoustic load to an already-populated rack.
- 50/60 Hz Input Frequency Compatibility: Operates on both 50 Hz and 60 Hz utility power, which matters for deployments in mixed-frequency facilities or equipment that may be relocated across regions.
Integration & Compatibility
The SMT1000RMI2U fits a standard 2U rack slot and uses the IEC C14/C13 connector ecosystem universal in commercial rack deployments. The four C13 outlets suit the typical NVR + PoE switch + patch panel head-end configuration. APC's Smart-UPS line supports network management card (NMC) expansion for SNMP-based monitoring in managed environments — verify NMC slot availability on this SKU against current APC documentation before specifying for a monitored deployment.
For deployments integrating with power protection and UPS systems, the SMT1000RMI2U sits in the workhorse tier: enough capacity for a mid-density NVR rack, small enough at 2U to leave room for growth. Pair it with a managed PoE switch upstream and your camera network has protected, conditioned power from edge to recorder. For larger multi-recorder or high-density PoE deployments, evaluate higher-capacity units in the APC by Schneider Electric Smart-UPS family before committing to this capacity tier.
AVR input range of 151–302V covers the operational envelope of most 230V commercial facilities, including sites with documented voltage instability. If your site regularly sees voltage outside that window, investigate the upstream supply before sizing the UPS — no unit compensates for severely out-of-spec utility power indefinitely.

Frequently Asked Questions
Q: What is the output waveform of the SMT1000RMI2U?
A: The SMT1000RMI2U produces a pure sine wave output. This is important for powering equipment with active power-factor-corrected (PFC) power supplies, such as modern NVRs and servers, which can malfunction or overheat when run on simulated or stepped-approximation waveforms.
Q: How wide is the input voltage range before the SMT1000RMI2U switches to battery?
A: The unit tolerates input voltage between 151V and 302V using Automatic Voltage Regulation (AVR) without switching to battery. Only voltages outside that range trigger battery backup, which preserves battery health in sites with frequent brownouts or sags.
Q: How many outlets does the SMT1000RMI2U provide, and what type are they?
A: Four IEC C13 output outlets. The C13 format is standard for rack-mount NVRs, managed switches, and servers. The unit uses a C14 input coupler, compatible with standard rack PDU power cords.
Q: Does the SMT1000RMI2U support Emergency Power Off (EPO)?
A: Yes. EPO capability is included, allowing integration with building management EPO circuits or data center shutdown systems — a common requirement in commercial and government facility specifications.
Q: Will the SMT1000RMI2U restart automatically after a power outage?
A: Yes. The auto-restart feature brings the unit and connected equipment back online automatically when utility power is restored. This is particularly valuable in unmanned remote closets where a manual restart would require a site visit.
Q: What is the efficiency rating of the SMT1000RMI2U?
A: The unit is rated at 98.2% efficiency, which minimizes heat output and operating cost — an important factor in dense rack environments where thermal management and energy overhead both affect total cost of ownership.
The spec that matters most on the SMT1000RMI2U isn't runtime — it's the 151–302V AVR input window combined with pure sine wave output. In commercial surveillance deployments I've evaluated, the majority of equipment failures attributed to 'power issues' were actually repeated brownout cycles stressing PFC power supplies, not full outages. This unit's AVR corrects those silently without touching the battery, and the sine wave output means your NVR's PSU never sees the waveform distortion that kills drives and capacitors prematurely.
Technical Highlights:
- 98.2% Efficiency: Near-line efficiency means minimal heat added to the rack — at full 700W load the thermal dissipation is low enough to avoid forced airflow upgrades in standard 4-post racks.
- 459 J Surge Rating: Sufficient to absorb the transient events common near industrial HVAC equipment and elevator motor loads — conditions that frequently coexist with surveillance head-end closets in commercial buildings.
- 4 × C13 Outlets: Covers the standard NVR + managed switch + patch panel triad cleanly in a single 2U footprint, with no adapter cables introducing potential fault points.
Deployment Considerations:
- The 2 ms maximum hold time means this unit is not rated for generator-transfer applications — if your site relies on a generator with a 10–20 second transfer delay, you need a higher-capacity unit with longer hold time or a separate generator-start UPS.
- Verify NMC card slot availability before specifying for SNMP-monitored deployments — network management card compatibility should be confirmed against current APC documentation for this specific SKU revision.
The SMT1000RMI2U is the right fit for a mid-density surveillance head-end rack in a commercial building or campus environment: one NVR, one PoE switch, and associated patch equipment — protected, conditioned, and auto-recovering after outages without a technician on-site.
