APC by Schneider Electric SMC1000I-2U 1000VA 2U Rack-Mount UPS

Overview

The APC by Schneider Electric SMC1000I-2U is a 1000VA / 600W line-interactive rack UPS built for 230V environments where power quality and physical footprint both matter. At 2U of rack height, it fits cleanly in edge equipment rooms, security head-end racks, and telecom closets without sacrificing the pure sine wave output that sensitive electronics — NVRs, managed switches, and IP PBX systems — require. If you're protecting gear that uses active power factor correction (PFC) power supplies, sine wave output is not optional; modified sine wave units cause premature shutdown or hardware damage under those loads. The SMC1000I-2U delivers clean sine wave across its full 600W capacity.

This unit belongs to the broader APC by Schneider Electric UPS lineup, a range well-represented in commercial security and IT infrastructure deployments. For buyers sourcing rack-mount UPS systems, the SMC1000I-2U sits in the mid-capacity tier — enough headroom for a small NVR stack and its attached switch, but sized conservatively so the battery doesn't carry more load than it can sustain through a credible outage window.

Key Features

• 600W / 1000VA Pure Sine Wave Output: Active PFC power supplies in modern NVRs, servers, and network appliances require sine wave during battery operation. The SMC1000I-2U's sine wave output means your equipment runs normally during an outage — not in a degraded or shutdown state. If you've had gear unexpectedly reboot during a brief outage on a modified sine wave unit, this is the spec that fixes it.
• 180–287V Wide Input Voltage Window: The unit accepts mains voltage ranging from 180V to 287V before switching to battery. In regions with notoriously variable power quality — common in industrial facilities or older commercial buildings — this wider window means the UPS stays on mains longer, preserving battery cycles for genuine outages rather than minor sags.
• 2U Rack-Mount Form Factor (432mm W × 406mm D × 86mm H): Two rack units is the standard trade-off between capacity and space in a 19-inch rack. At 432mm wide and 406mm deep, it fits standard 600mm-deep two-post and four-post racks. Verify your rack depth before ordering — some shallow-depth wall-mount enclosures won't accommodate the 406mm chassis.
• RJ-45 Serial and USB Interface Ports: Both management interfaces are included on the same unit. USB connects directly to a host for software-based monitoring and graceful shutdown. The RJ-45 serial port accommodates network management card options or legacy SNMP integration where USB isn't available on the protected host. For remote monitoring in an unmanned equipment room, pair this with a compatible network management card to get SNMP traps and email alerts without a dedicated management server on-site.
• 459-Joule Surge Energy Rating: Surge suppression is built in, rated at 459 joules. This handles typical transient spikes on commercial power circuits. For sites near heavy inductive loads (HVAC, elevators, industrial equipment), consider whether additional surge protection at the panel is warranted — the UPS surge rating handles downstream transients, not catastrophic upstream events.
• 42 dB Audible Noise: At 42 dB, this unit is quiet enough for office-adjacent installations and unmanned closets where fan noise bleeds into occupied spaces. For context, 42 dB is roughly equivalent to a quiet office environment — audible if you're standing next to it, but not disruptive through a closed door.
• 3-Hour Typical Recharge Time: After a full discharge, the SMC1000I-2U returns to full battery capacity in approximately 3 hours. In environments with frequent short outages (utility grid instability, generator startup delays), recharge speed matters — 3 hours is adequate for most commercial sites running generator backup, where the window between events is measured in days, not hours.
• 0–40°C Operating Temperature Range: Covers standard commercial equipment room conditions. This unit is not rated for outdoor or uncontrolled environments. If your rack lives in an unconditioned space that regularly exceeds 40°C in summer, derate expected battery life accordingly — sealed lead-acid batteries lose capacity and cycle life significantly above 25°C.
• Sealed Lead-Acid Battery: Sealed, valve-regulated lead-acid (VRLA) chemistry means no liquid electrolyte maintenance, safe for indoor rack installation, and no special ventilation requirements beyond standard equipment room airflow. Battery replacement is a routine field procedure — plan for it on a 3–5 year cycle depending on operating temperature and discharge frequency.
• C-Tick, CE, GOST, VDE Approvals: Carries regulatory approvals for deployment in Australia/New Zealand (C-Tick), the European Union (CE, VDE), and Russia/CIS (GOST). Verify local authority-having-jurisdiction (AHJ) requirements before specifying for critical infrastructure projects outside these regions.

Integration and Compatibility

The SMC1000I-2U outputs 230V nominal at 50/60 Hz ±3 Hz, making it appropriate for 230V-standard regions (EU, UK, AU, Middle East, parts of Asia). It is not a dual-voltage unit — confirm your load equipment is rated for 230V input before deploying. Output voltage distortion stays below 5% under load, which keeps sensitive electronics within their input tolerance bands.

The USB and RJ-45 serial interfaces support APC's PowerChute software for graceful OS shutdown on connected servers and workstations. For NVR deployments, most major VMS platforms (Milestone, Genetec, Avigilon) support UPS-triggered graceful shutdown via PowerChute or direct USB UPS signaling — check your VMS vendor's documentation for the specific integration path. Pair with a managed PoE switch on the protected circuit to keep IP cameras online during the UPS runtime window.

The SMC1000I-2U (often searched as SMC1000I 2U) weighs 20.52 kg — plan for two-person rack installation, particularly in overhead or bottom-of-rack positions.

Frequently Asked Questions

Q: Does the SMC1000I-2U output pure sine wave during battery operation?

A: Yes. The SMC1000I-2U produces pure sine wave output during both mains and battery operation. This is critical for equipment with active PFC power supplies — including most modern NVRs, servers, and managed switches — which can malfunction or shut down unexpectedly when fed a modified sine wave during a power event.

Q: What is the output voltage of the SMC1000I-2U, and is it suitable for North American 120V equipment?

A: The SMC1000I-2U outputs 230V nominal and is designed for 230V mains environments (EU, UK, Australia, Middle East, etc.). It is not compatible with 120V North American equipment without a step-up transformer. For North American 120V deployments, a different SKU is required.

Q: What input voltage range does the SMC1000I-2U tolerate before switching to battery?

A: The unit accepts mains input from 180V to 287V while remaining on utility power. Outside this range, it switches to battery automatically. The nominal input is 230V at 50/60 Hz ±3 Hz.

Q: What is the warranty on the SMC1000I-2U?

A: The SMC1000I-2U carries a 2-year manufacturer warranty.

Q: Can I add network SNMP monitoring to the SMC1000I-2U?

A: The SMC1000I-2U includes RJ-45 serial and USB interface ports. An optional APC network management card (sold separately) can be installed to enable SNMP monitoring, email alerts, and remote management. The USB port also supports direct connection to APC PowerChute software for graceful shutdown of a connected host.

Q: How long does the SMC1000I-2U take to recharge after a full discharge?

A: Typical recharge time after a full discharge is approximately 3 hours under normal operating conditions.

The SMC1000I-2U is the unit I spec when a security integrator needs rack-mount battery backup in a 230V region and the NVR stack uses modern switching power supplies — which virtually all do. The 600W / 1000VA capacity at pure sine wave output is what separates it from cheaper alternatives that'll cause your NVR to reboot mid-outage because the modified sine wave confuses the active PFC circuit.

Technical Highlights:

• Pure Sine Wave at Full 600W: Not a reduced-output sine wave — the full 600W rated capacity is available as clean sine wave, which means your protected load sees the same power quality on battery as on mains. No derating, no compatibility asterisks for PFC equipment.
• 180–287V Input Window: That 107V tolerance range is meaningful in older commercial buildings where tap voltage drifts. The UPS stays on utility across that window, which matters for battery longevity — every unnecessary battery switch is a partial discharge cycle.
• 42 dB Operating Noise: In a head-end room shared with an interview suite or dispatch center, fan noise accumulates. At 42 dB this unit isn't silent, but it won't dominate the acoustic environment through a standard equipment room door.

Deployment Considerations:

• At 20.52 kg, this is a two-person rack install. Don't let a solo technician attempt overhead or low-bay mounting — the weight distribution in a 2U chassis at that mass creates a real drop risk.
• The 0–40°C operating range is standard, but sealed lead-acid batteries lose roughly 50% of their rated capacity at 40°C versus 25°C. If your equipment room runs warm in summer, expect shorter runtime than the nameplate suggests and plan battery replacement on a shorter cycle.

This is the right call for a 230V security head-end rack running an NVR, managed PoE switch, and access control panel — the load profile fits the 600W ceiling cleanly, and the pure sine wave output means you won't spend an afternoon chasing a phantom reboot that turns out to be a power quality issue during a brief utility event.
