PRODUCT DESCRIPTION
APC Smart-UPS C, Line Interactive, 1000VA, Rackmount 2U, 230V (SMC1000I-2U) - 2 Years Local Warranty
Product status: the SMC1000I-2U has reached end of commercialisation at Schneider Electric (19 August 2025) and is superseded by the SmartConnect model APC SMC1000I-2UC. This page is maintained as the reference datasheet for the SMC1000I-2U. Contact SourceIT for remaining stock, or for the current replacement.
APC SMC1000I-2U — 1,000 VA / 600 W Line-Interactive UPS for Singapore 230V Power
The APC Smart-UPS SMC1000I-2U is a line-interactive uninterruptible power supply rated at 1,000 VA / 600 W for 230 V single-phase supply — the standard Singapore mains configuration. Line-interactive topology means the UPS sits between your equipment and the PUB grid, filtering and correcting the incoming supply continuously and switching to battery only when the mains falls outside its window. For the brownouts and brief dips that arrive with a Singapore thunderstorm, that is exactly the right behaviour: the load never notices, and the battery is not cycled unnecessarily.
Automatic Voltage Regulation Protects Battery Life
Automatic Voltage Regulation (AVR) is the feature that separates a Smart-UPS from a basic backup unit. When mains voltage sags or surges, AVR corrects it using the transformer rather than dropping to battery. On a supply that dips repeatedly — a comms cabinet on a shared riser, an SME office at the end of a long feed, a site near heavy plant — a UPS without AVR will discharge and recharge dozens of times a week, and the battery ages accordingly. The SMC1000I-2U rides those events through on mains, so the battery is held in reserve for real outages.
Sine Wave Output for Servers, Switches and Active-PFC Power Supplies
Schneider Electric specifies sine wave output for the SMC1000I-2U. This is the specification to check before you buy: current server and workstation power supplies use active power factor correction, and active-PFC supplies can alarm, cut out or refuse to transfer on the step-approximated waveform used in entry-level UPS models. On a sine wave they behave normally. Output connections are 4 × IEC 60320 C13, plus 2 × IEC jumpers, and output voltage is configurable for 220 V, 230 V or 240 V nominal.
2U Rack Deployment in a Comms Cabinet or Server Room
The SMC1000I-2U occupies 2U of your rack budget, measuring 89 × 432 × 406 mm (H × W × D) at 20.52 kg (shipping 22.33 kg). Rack mounting brackets included in the box (rails are not supplied). Two things are worth checking before you order: the chassis depth against your cabinet, since UPS units are frequently deeper than the servers they protect, and the mounting position — at this weight the UPS belongs at the bottom of the rack. Front-panel LCD lets you read load, battery status and events without a laptop or a network connection.
Simple Management, Hot-Swap Batteries and Local Singapore Supply
The Smart-UPS C range keeps management deliberately simple: serial and USB ports drive PowerChute Serial Shutdown for unattended, graceful shutdown of an attached server, and there is no SmartSlot, so a network management card cannot be fitted — worth knowing before you specify it for a monitored rack. The battery cartridge is user-replaceable and hot-swappable, so the load stays protected during a battery change. SourceIT supplies the SMC1000I-2U in Singapore with a GST invoice and local warranty support.

Compatibility & Runtime
What you can plug in
The SMC1000I-2U delivers 1,000 VA / 600 W at 230 V. Size the UPS on the watt figure, not the VA figure: add up the real power draw of everything you intend to protect and keep it comfortably below 600 W. Output is via 4 × IEC 60320 C13, plus 2 × IEC jumpers. Most rack servers, switches, firewalls and NAS units ship with a C13 cordset, so they connect directly.
Sine wave output and active-PFC power supplies
Schneider Electric specifies sine wave output for the SMC1000I-2U. That matters in a server room: modern active power-factor-corrected server and workstation PSUs can shut down or alarm on the step-approximated waveform used by entry-level UPS models, but they run normally on a sine wave. If you are protecting active-PFC hardware, this is the part of the specification to check.
Transfer time on the SMC1000I-2U is 2 ms typical, comfortably inside the ride-through window of a typical server power supply.
Runtime
Runtime is entirely a function of load — a UPS at 30% load runs far longer than the same UPS at 90%. Schneider Electric does not publish a runtime table for the SMC1000I-2U, so SourceIT does not quote one here. Tell us your actual load in watts and we will size the runtime for you before you order.
Replacement battery
The SMC1000I-2U takes the APC APCRBC124 replacement battery cartridge — one per UPS. The cartridge is user-replaceable and hot-swappable, so the load stays protected while you change it. RBC part numbers are not interchangeable between Smart-UPS models, or between a standard model and its SmartConnect equivalent, so order by the part number above. In Singapore's humidity and year-round air-conditioned server rooms, plan on replacing the cartridge within the 4–6 year service window rather than waiting for a failed self-test.
Rack fit
The SMC1000I-2U occupies 2U of rack space in a 19-inch cabinet, with a chassis depth of 406 mm and a net weight of 20.52 kg (shipping 22.33 kg). Check the depth against your cabinet before ordering, and mount it at the bottom of the rack — at this weight it is the heaviest thing in most comms cabinets. Rack mounting brackets included in the box (rails are not supplied).
Management and monitoring options
The Smart-UPS C range has no SmartSlot, so a Network Management Card cannot be fitted to the SMC1000I-2U. Monitoring is over the USB or serial port using PowerChute Serial Shutdown, which handles unattended shutdown of the attached server. If you need SNMP or a web interface, move up to a Smart-UPS SMT model with a SmartSlot, or choose a SmartConnect model for cloud monitoring.

Frequently Asked Questions — APC SMC1000I-2U
What do VA and W mean, and how do I size the SMC1000I-2U for my load?
VA is apparent power and W is real power; the SMC1000I-2U is rated at 1,000 VA / 600 W and the watt figure is the one that limits what you can connect. Add up the real draw of every device you want to protect — a small rack server is typically 150–350 W, a switch 20–60 W, a firewall 20–40 W — and keep the total comfortably below 600 W so you have both headroom and useful runtime. If the sum is close to the limit, size up rather than run the UPS at 90%.
How long will the SMC1000I-2U run on battery?
That depends entirely on the connected load, and Schneider Electric does not publish a runtime table for this model, so SourceIT does not quote one. As a rule, a line-interactive UPS of this class is designed to ride out the brief dips and short outages that are typical of the PUB grid and to give you time for a clean shutdown — not to run a rack for hours. Send us your load in watts and we will size it properly.
What is the difference between the SMC1000I-2U and the SmartConnect version (SMC1000I-2UC)?
The SmartConnect build adds a dedicated Ethernet port for APC's free cloud monitoring portal, giving remote status and alerting. It is a different build, not a badge: on the Smart-UPS C rackmount pair, for example, the standard model transfers in 2 ms typical while the SmartConnect model is specified at 6 ms typical and 10 ms maximum, and the replacement battery cartridges are different part numbers. Do not assume specs carry across.
Is the output a true sine wave, and will it work with an active-PFC server power supply?
Yes — Schneider Electric specifies sine wave output for the SMC1000I-2U. Active power-factor-corrected PSUs, which most current servers and many workstations use, can trip or alarm on the step-approximated waveform found in entry-level Back-UPS and Easy UPS models, but they run normally on a sine wave. This is one of the main reasons to choose a Smart-UPS over a home-office model for server-room equipment.
Which replacement battery does the SMC1000I-2U take, and can I change it myself?
It takes the APC APCRBC124 replacement battery cartridge, one per unit. It is user-replaceable and hot-swappable, so the connected load stays protected during the swap. Expected service life is 4–6 years; Singapore's ambient heat and humidity tend to push VRLA batteries toward the shorter end of any published range, so budget for replacement rather than waiting for a failed self-test. RBC part numbers are not interchangeable across Smart-UPS models — order by part number.
How much rack space does it need, and are rails included?
The SMC1000I-2U is a 2U chassis measuring 89 × 432 × 406 mm (H × W × D) and weighing 20.52 kg (shipping 22.33 kg). Rack mounting brackets included in the box (rails are not supplied). Check the depth figure against your cabinet — UPS chassis are often deeper than the servers around them — and mount it low in the rack for stability.
Can I monitor the SMC1000I-2U over the network?
No. The Smart-UPS C range has no SmartSlot, so a Network Management Card cannot be fitted. Monitoring is via USB or serial to an attached server running PowerChute Serial Shutdown. If SNMP or web-based monitoring is a requirement, choose a Smart-UPS SMT model, which has a SmartSlot, or a SmartConnect model for cloud monitoring.
Is the SMC1000I-2U covered by warranty in Singapore?
Yes. Every APC SMC1000I-2U sold by SourceIT comes with local Singapore warranty and a GST invoice; APC backs the SMC1000I-2U with a 2-year manufacturer warranty. The Smart-UPS C user guide and the product datasheet both state a flat two years worldwide, with no separate European and rest-of-world figure, so that is the term that applies in Singapore.
