APC Smart-UPS 1000VA 700W Tower Line-Interactive UPS 120V SMT1000C

Key Features

• Line-interactive design rated 1000 VA and 700 W, correcting sags and swells from mains without dropping to battery for every wobble.
• Sine wave output at 120 V, which is what active power-factor-corrected server supplies need to see.
• Output panel of 8 x NEMA 5-15R.
• Input on NEMA 5-15P.
• Tower chassis rather than rack-mount, weighing 44.3 lb (20.1 kg).
• Sealed lead-acid battery, recharging in about 3 hours from flat.
• SmartConnect Ethernet port for APC's cloud monitoring portal, giving status and alerting from a browser with no local software to install.
• Surge energy rating of 680 joules on the input stage.
• Quoted at 41 dBA, quiet enough for an occupied office or a consulting room.
• Rated for 32-104 F (0-40 C) operating temperature.
• Backed by 3 years repair or replace on the unit, excluding the battery, plus 2 years on the battery.

What this unit is

The APC Smart-UPS SMT1000C is a line-interactive uninterruptible power supply rated at 1000 VA and 700 W. Output is sine wave at 120 V, which is what active power-factor-corrected server and network supplies expect to see. The power factor works out at 0.70, so the watt rating rather than the VA rating is the number that runs out first on a modern IT load. Line-interactive means the unit runs the load from filtered mains most of the time, correcting modest sags and swells with an automatic voltage regulator rather than dropping to battery for every wobble. Battery is reserved for real outages, which is easier on the cells and cheaper to run.

Power and outlets

Input is 120 V through a NEMA 5-15P connection. The output panel carries 8 x NEMA 5-15R. Input frequency is 50/60 Hz +/- 3 Hz with auto-sensing. Match the receptacles to the equipment before ordering rather than after. A UPS with the right wattage and the wrong sockets is a shopping trip for adapters, and adapters on a rack power path are exactly what an audit picks up. If the outlet mix is close but not exact, a rack PDU downstream of the UPS is usually the cleaner answer than a handful of pigtails, and we stock those too.

Battery and runtime

The battery is sealed lead-acid, internal to the unit. APC quotes a typical recharge time of 3 hours from a full discharge, which is the figure that matters when outages arrive in pairs rather than singly. Sealed lead-acid batteries are consumables, not permanent parts. Expect to replace them somewhere in the three-to-five-year range depending on how warm the room runs, and treat that as planned maintenance rather than a fault. Heat is what kills them. Every few degrees above a normal room temperature meaningfully shortens service life, so the same unit in a ventilated rack will outlast the one tucked into a warm cupboard by a wide margin.

Form factor and size

This is the tower build rather than a rack-mount one. Dimensions are 8.62 in (21.9 cm) H x 6.73 in (17.1 cm) W x 17.28 in (43.9 cm) D. Net weight is 44.3 lb (20.1 kg). One person can handle it, but it is dense for its size, so mount it low in the rack rather than high. Check the depth against the rack before ordering. A UPS that fits the rails but not the cabinet is the most common surprise on an install, and rear cable service space has to come out of the same measurement.

Management and monitoring

The data sheet records 1 free SmartSlot, which is where an accessory card goes if you add one later. The sheet records the interface ports as SmartConnect Ethernet port: for cloud monitoring, feature availability varies by terms of use. SmartConnect is present on this model: an Ethernet port dedicated to APC's cloud portal, which gives status, alerting and firmware handling from a browser with no local software to run. A network management card matters more than it sounds. Without one the unit reports only to whatever is plugged into its USB or serial port, which means one machine sees the alarms and everything else finds out when it loses power.

Environment and noise

Operating temperature is 32-104 F (0-40 C). Acoustic noise is quoted at 41 dBA at one metre. Surge energy rating is 680 joules. Acoustics decide where a unit like this can live. Anything at or below the mid forties is quiet enough for an occupied office or a consulting room; above about fifty it belongs behind a door, because the fans do not stop when the load is light. The surge rating covers the everyday transients that arrive down the mains, not a direct strike. Take it as a measure of how much abuse the input stage will absorb before it stops protecting the load.

In the box

APC lists the following in the carton for this part number: User Manual and USB cable. Warranty is 3 years repair or replace on the unit, excluding the battery, plus 2 years on the battery. Carton contents on APC part numbers move between data sheet revisions more than you would expect, and rail kits in particular come and go. The list above is what the current sheet for this exact part number prints, and we would rather quote that than a tidier list assembled from a sibling model.

If you are protecting a rack, a closet or a plant-room load and need 1000 VA of line-interactive backup with the outlet set described above, the APC Smart-UPS SMT1000C is a sound choice, and we hold it in stock. Contact us to learn more or secure this solution for your business today.
