APC Smart-UPS, Line Interactive, 750VA, Rackmount 2U, 230V (SMT750RMI2U) - 3 Years Local Warranty
Product status: the SMT750RMI2U has reached end of commercialisation at Schneider Electric (6 August 2026) and is superseded by the SmartConnect model APC SMT750RMI2UC. This page is maintained as the reference datasheet for the SMT750RMI2U. Contact SourceIT for remaining stock, or for the current replacement.
APC SMT750RMI2U — 750 VA / 500 W Line-Interactive UPS for Singapore 230V Power
The APC Smart-UPS SMT750RMI2U is a line-interactive uninterruptible power supply rated at 750 VA / 500 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 SMT750RMI2U 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 SMT750RMI2U. 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 SMT750RMI2U occupies 2U of your rack budget, measuring 89 × 432 × 406 mm (H × W × D) at 17.27 kg. Rack mounting support rails included in the box. 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.
Management, Hot-Swap Batteries and Local Singapore Supply
Serial and USB ports drive PowerChute Serial Shutdown for unattended, graceful shutdown of an attached server. One empty SmartSlot accepts an optional APC Network Management Card 3 (AP9640 or AP9641) when you need SNMP, a web interface or EcoStruxure IT — network management is an option on this model, not a built-in feature. The battery cartridge is user-replaceable and hot-swappable, so the load stays protected during a battery change. SourceIT supplies the SMT750RMI2U in Singapore with a GST invoice and local warranty support.

Compatibility & Runtime
What you can plug in
The SMT750RMI2U delivers 750 VA / 500 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 500 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 SMT750RMI2U. 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 SMT750RMI2U 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 SMT750RMI2U, 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
Schneider Electric does not publish a replacement battery cartridge part number for the SMT750RMI2U in the documents available for this SKU, and third-party listings disagree, so SourceIT does not state one here. Email sales@sourceit.com.sg with your serial number and we will confirm the correct cartridge against Schneider's battery selector before you order.
Rack fit
The SMT750RMI2U occupies 2U of rack space in a 19-inch cabinet, with a chassis depth of 406 mm and a net weight of 17.27 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 support rails included in the box.
Management and monitoring options
The SMT750RMI2U has serial and USB ports and one empty SmartSlot. Networked monitoring is not built in — you add it by fitting an APC Network Management Card 3 (AP9640), or AP9641 if you also want environmental sensor inputs. An AP9613 Dry Contact I/O card suits building-management integration. For directly attached servers, PowerChute Serial Shutdown handles graceful shutdown over USB or serial.

Frequently Asked Questions — APC SMT750RMI2U
What do VA and W mean, and how do I size the SMT750RMI2U for my load?
VA is apparent power and W is real power; the SMT750RMI2U is rated at 750 VA / 500 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 500 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 SMT750RMI2U 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 SMT750RMI2U and the "IC" SmartConnect version (SMT750RMI2UC)?
The SmartConnect models add a dedicated Ethernet port that reports the UPS to APC's free SmartConnect cloud portal, giving remote status and alerting without a management card. They are genuinely different builds — not just a badge — and some specifications, including transfer time and the replacement battery cartridge part number, differ between a standard model and its SmartConnect equivalent. The SMT750RMI2U is the standard build. The "NC" suffix on other Smart-UPS models means a Network Management Card is factory-fitted; that is different again.
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 SMT750RMI2U. 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 SMT750RMI2U take, and can I change it myself?
The battery is user-replaceable and hot-swappable. However, Schneider Electric does not publish a cartridge part number for this exact SKU in the documents available to us, and third-party listings disagree, so we will not guess one. Email sales@sourceit.com.sg with your serial number and we will confirm it against Schneider's official battery selector.
How much rack space does it need, and are rails included?
The SMT750RMI2U is a 2U chassis measuring 89 × 432 × 406 mm (H × W × D) and weighing 17.27 kg. Rack mounting support rails included in the box. 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 SMT750RMI2U over the network?
Not out of the box. The unit has serial and USB ports and one empty SmartSlot; network management is an add-in card, not a built-in feature. Fit an AP9640 Network Management Card 3 for SNMP and a web interface, or an AP9641 if you also want temperature and humidity sensor inputs. Without a card, use PowerChute Serial Shutdown on the attached server.
Is the SMT750RMI2U covered by warranty in Singapore?
Yes. Every APC SMT750RMI2U sold by SourceIT comes with local Singapore warranty and a GST invoice; APC backs the SMT750RMI2U with a 3-year UPS / 2-year battery manufacturer warranty. Schneider Electric's Singapore support FAQ and the product datasheet both state three years on the UPS hardware and two years on the battery for the Smart-UPS SMT range, with no separate European and rest-of-world figure, so that is the term that applies here.
