## Description

Over 20 million units sold - the UPS you can trustAPC award-winning Smart-UPS is the most popular UPS in the world for servers, storage and networks. Trusted to protect critical data and equipment from power problems by supplying clean and reliable network-grade power. In addition to legendary reliability and manageability, Smart-UPS have extremely high efficiency at low, medium and high load levels making them ideal for today's multi-core or virtualized servers that have varying load consumption. Available in a variety of form factors (tower, rack mount, rack/tower convertible) there is a model for every application and budget. Rack mounted Smart-UPS are ideal for powering Blade or density optimized servers in a distributed power protection environment as the primary or redundant protection. Smart-UPS models have long been considered the benchmark for all network and server UPS's. Smart-UPS feature a 16-segment LED display, extended range automatic voltage regulation (AVR), and pure sine wave output on battery. Additional manageability options are available through the Smart-Slot interface, which is an internal slot for the installation of optional accessory cards. The extended run Smart-UPS XL has the capability to add external battery packs to scale runtime from minutes to hours typically needed for converged voice and data networks. The entry level Smart-UPS SC is an economical choice for small and medium businesses looking to protect small switches, networking devices and point-of-sale (POS) equipment.

Review: Great Battery Backup Unit Latest Model is even Better! - This model is even better than the older family this one has a LCD with important information and has multiple ways to configure as a set of ports (group) that can be programmed to turn on/off remotely (bouncing dvr, firewalls or other unresponsive equipment or to control other devices or even lights) Love apc, APC has build a name since I remember APC was always among the names respected for their expertise and performance, for me they are soo good that I even have bought a few for home, this UPS units are flawless as they detect correct and protect power surges, peaks and drops and they will keep you running for at least 10 minutes (at full capacity 900watts) needless to say a regular computer/monitor with a router and a small inkjet printer will last up to 40 minutes of work (I have worked under a full blackout finishing up work and it did last around the 40-45 minutes I was impressed) I would say that the unit was probably at 18 to 23% load at the time using OEM APC Battery Pack ( I would always advise use of oem apc battery packs as they are build using an advanced technology that not everyone can replicate and under load most batteries will perform poorly after a few months while the APC OEM stay strong up to 5 years of use and abuse I seen other units like SUA1500RM2 and SUA3000 under Heavy Loads this units performed Magnificent, I have seen a sua1500 that was 4 years old loaded with a dell t710 and a r210 servers switch and kvm, it was close to 90% and under a storm it took countless power spikes/drops even a 5 minute power outage, you could see the device working even before you even notice anything abnormal, the servers keep working all night with no issues, Needless to say I am bias when it comes to APC they really know their stuff. I have used other brands - home and enterprise - and most of them fail when they under heavy load and under stress, (power blackout or during storms) my best guess is the engineering behind the circuitry that does the inversion and the simply well made transformer, I have seen units power off with depleted batteries and coming right back up after the power is restored like nothing, other brands fail to do so or simply will require the user to turn them on, or will require expensive attachments to perform somewhat like their Great APC counterparts.
Review: Excellent small-office/home-office server UPS. - I have two of these units, each powering one of a server's dual power supplies (redundant power supplies, and redundant SmartUPSs). These are stable, excellent units with a great amount of battery runtime (on my 150-watt server, I get approximately 90 minutes on each battery). The software they come with works well, except that it can't detect two units, only one, connected USB. I've taken to just uninstalling the software and using Windows' built-in power management for the batteries which seems to work just fine. Good amount of controls and information provided by the alpha-numeric LCD readout. Prior models of this unit seem to last about 5-6 years before the electronics give up and you start getting errors even after replacing the battery, so I'm hoping to get a little longer on this newer generation. In all, very happy with these units; they're quiet and they just work.

## Questions & Answers

**Q: What if someone wanted to use this item for, let's say, a sump pump.  Whould this be a good idea!???**
A: I am an engineer for Schneider Electric. These Are not designed to run motor loads due to the in rush current of a motor when it starts. There are better alternatives for that particular application such as a basement watch dog that has a DC motor with high current capability and a charging system. To even consider running a sump pump on a UPS it must be sized at least 6 times the motors run current.  1/2 HP sump pump on average pulls 10 amps running. Which would mean a UPS capable of delivering 60 amps. 60x120= 7.2kW or about 8 times the power that this UPS is capable of delivering. Even considering only the running amps of this UPS and a 1/2 HP pump it would be overloaded as 900 watts equates to 7.5 amps.

**Q: There appears to be 8 outputs, how many are actually Battery outputs and not just surge protected outputs?**
A: As mentioned, all of the outlets in this series are battery-protected.  The number of outlets will depend on model.  Since this Amazon Q/A is being attached to multiple models, here's the count for all the models in this series (based on APC's product manuals):SMT750, SMT1000RM2U, SMT1500RM2U - 6 outletsSMT1000, SMT1500, SMT2200, SMT2200RM2U, SMT3000RM2U - 8 outletsSMT3000, SMT3000RM2U (230v) - 9 outlets (8 15A, 1 20A)

**Q: Does the 1500VA pull 15amps or does it just need to be put on a 15 amp circuit?**
A: Assuming 120v at the outlet, 1500VA would be about 12.5 amps.  I doubt the UPS would draw that much unless under 100% load.  If that's the case, you likely need a larger model.  Perhaps if it we're under 100% load and charging the batteries...  In any case, a residential outlet should be rated to at least 15 amps...

**Q: what type of wall plug does it use?  canit plus into a standard outlet type?**
A: Depends on the model you get.  The 750VA, 1000VA and 1500VA models all have standard 15A plugs.  The 2200VA model uses a 20A plug and needs a 20A outlet (and circuit, of course).  Then 3000VA model uses a 30A locking plug and needs a corresponding outlet and circuit.

### ⭐⭐⭐⭐⭐ It works! Fan only runs to charge the battery
*by T***S on October 12, 2013*

I was intimidated because of the reviews complaining about the fan noise. When I installed the device, the fan indeed was loud. But once the battery was fully charged, the fan has either completely stopped or is going too slow to notice. The other reviews are a few years old, so perhaps APC changed the fan behavior since then. I initially bought a CyberPower CP1500AVRLCD to save money and although it said it was going to last long on the battery, every power outage resulted in an instantaneous crash of my PC. It was utterly useless, perhaps because of the sign wave quality on that CP model. So I replaced it with this APC SMT-1500 and the CyberPower is assigned to my router now, all is good. EDIT: I am quoting this from an excellent review by Neil E. Isenberg " This (APC SMT-1500) Has fan (APC estimates 45dB max) which runs when: - The battery charges - The unit supplies battery power - The temperature hits 104F - The load is over 75% of unit wattage capability (675W+). " If that is true, it would be wise to buy a unit that is larger than you need to avoid the 75% load condition. I have a 5GHz custom built gaming tower/room heater and a 25" LCD monitor and it usually does not provide over 12% normal load on this UPS and has never gotten even close to 75%.
