APC Smart-UPS SRT 3000VA 2700W 2U Rackmount Online UPS 120V SRT3000RMXLA

Key Features

• Double-conversion online design rated 3000 VA and 2700 W, feeding the load from the inverter continuously so there is no transfer break.
• Sine wave output at 120V, which is what active power-factor-corrected server supplies need to see.
• 9 receptacles on the output: 8 x NEMA 5-20R and 1 x NEMA L5-30R.
• Input on NEMA L5-30P, 8 ft (2.44 m) cord.
• 2U rack-mount chassis weighing 69 lb (31.3 kg).
• Maintenance-free sealed lead-acid with suspended electrolyte battery, recharging in about 3 hours from flat.
• Surge energy rating of 340 joules on the input stage.
• Quoted at 55 dB, so it belongs behind a door rather than on a desk.
• 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 SRT SRT3000RMXLA is a double-conversion online uninterruptible power supply rated at 3000 VA and 2700 W. Output is sine wave at 120V, which is what active power-factor-corrected server and network supplies expect to see. The power factor works out at 0.90, so the watt rating rather than the VA rating is the number that runs out first on a modern IT load. Double conversion means the load is fed continuously from the inverter, with incoming mains used only to run the rectifier and charge the battery. There is no transfer time to speak of and no exposure to whatever the incoming waveform is doing, which is why this topology is specified for equipment that will not tolerate a break.

Power and outlets

Input is 120V through a NEMA L5-30P, 8 ft (2.44 m) cord connection. The output panel carries 9 receptacles: 8 x NEMA 5-20R and 1 x NEMA L5-30R. Input frequency is 40 - 70 Hz (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 maintenance-free sealed lead-acid with suspended electrolyte, 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.

Form factor and size

This is the 2U rack-mount build. Dimensions are 3.35 in H x 17.0 in W x 25.0 in D (85.0 x 432.0 x 635.0 mm). Net weight is 69 lb (31.3 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. Weight distribution matters as much as the rail fit. Batteries make a UPS the densest thing in most cabinets, so it belongs at the bottom for stability and for the sake of whoever eventually has to remove it.

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 RJ-45 Serial, Smart-Slot, USB. 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. With network management in place the unit gets its own address, its own alert rules and its own log, and it can trigger graceful shutdowns across several servers rather than just the one holding the cable.

Environment and noise

Operating temperature is 32-104 F (0-40 C). Acoustic noise is quoted at 55 dB at one metre. Surge energy rating is 340 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: CD with software, Documentation CD, Installation guide, Rack Mounting brackets, Rack Mounting support rails, USB cable and Warranty card. 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 3000 VA of double-conversion online backup with the outlet set described above, the APC Smart-UPS SRT SRT3000RMXLA is a sound choice, and we hold it in stock.
