Tripp Lite 650VA UPS Battery Back Up, 350W, Rack-Mount/Tower, LCD Display, AVR, USB, DB9 (OMNI650LCD)

This is an excellent UPS. And, Tripp Lite makes great products in general. I have never had a significant problem with a Tripp Lite product, and, in fact, I have been using numerous Tripp Lite surge protectors since 1992, and have purchased 6 additional Tripp Lite surge protectors over the past 2 years for additional applications.[NOTE:I have added an update/addendum at the end of this review offering some hints on dealing with the burnt plastic odor that -- according to many other reviewers, and also in my own experience -- seems to be emitted by some of these UPSs -- and was emitted by my own device -- when new and first put into use.]After having experienced numerous unexpected failures with some 1300 VA APC UPSs over the past 5 years, I finally performed extensive due diligence (i.e., research) regarding the most reliable and robust UPSs on the market today, and I recently made the decision to switch to buying only Tripp Lite UPSs for all of my new purchases of UPSs (e.g., for replacement of old UPSs that have died, and for use in new service applications).My new Tripp Lite SMART1300LCDT arrived here the other day, and I installed it immediately as the backup UPS for the router, cable modem, an external hard drive, and one of my PC monitors, and I am very impressed with this backup UPS. The high quality of design and manufacture is quite evident. It is not over-reaching to state that I simply love it!I will note that this UPS has only four battery backup power AC outlets on the rear panel, and they are spaced quite closely together. Therefore, when installing this UPS as a replacement for an older UPS from another brand that had failed in service, I quickly discovered that there was not sufficient room among the four backup power outlets on the back panel to allow me to plug in the three "wall wart"-type AC power adapters 9one each for my router, modem and external HD) and also the plug for my monitor, due to the extra space required for the "wall wart" AC power adapters. So, I plugged one AC power adapter and the plug for my monitor into the battery backup power AC outlets on the rear panel, along with the plug for the 4 foot cable for an external power strip (the power strip has six (6) widely-spaced outlets and is NOT surge protected; it seems to be important to most of the the manufacturers (including Trip Lite) of UPSs that any external AC power strip plugged into the backup AC power outlets must NOT contain any surge protectors or radio-frequency filters (RFI filters), probably due to the high rise-time of the square waves that make up the "modified sine wave" AC output of the UPSs when they are running in battery backup power mode.Bottom line is that I love this UPS, and it has easily passed all of my basic tests. I will add more notes, as warranted, as I accrue more experience with this UPS as the months pass.In closing this section, I will mention that my new UPS, once it had been put into services, did start to emit a moderately-strong "new electronic device" odor, one akin to the smell of burning plastic, and in the Addendum below I will tell you how I chose to manage the odor. However, despite the fact that my new unit has been emitting this moderately-strong level of odor for the past few days, I nonetheless choose to give this UPS a full 5 stars in my review, simply because of the high quality and robustness of the unit, and its proven track record for reliability. So, it still gets 5 stars, and, in fact, I plan to purchase several more of these units over the next year or two for use in other applications.BTW, I called Tripp Lite's Tech Support line to discuss the "new device" odor, not because I was seeking to procure a replacement unit, but because I was wondering exactly what internal components were emitting the odor, and I am expecting to hear back from one of their senior engineers within the next few days with some detailed answers to my questions. In the meantime, the low-level tech support person with whom I spoke (and who agreed to my request that he escalate my questions up the line to the engineers that designed this unit) suggested the following likely source for the odor: he reminded me that this UPS contains a rather hefty power transformer, and that these transformers are potted or sealed in an insulating compound that is similar to a varnish or plastic resin sealant. He suspected that the new transformer, once the UPS has been first put into service, heats up (this is natural, of course) and that this heating "bakes" the potting compound/sealant, and that the potting compound then emits some gases as it finishes curing or setting during the first few days or weeks that the UPS is in serviceAddendum:- Managing the Burnt Plastic Odor Emitted by Some of these UPSs When New and for the First Few Days or Weeks of UseAs you have likely already noticed, a number of other reviewers have mentioned that their new units (as did mine within a few hours of having turned it on when first installed) emitted an odor similar to that of burnt plastic when first put into use, and that the odor lasted for anywhere from a few days to a few weeks, or even longer; some of these reviewers had even reported the odor as having been quite strong and quite offensive to them. Now, I do want to point out that several of these reviewers who reported the offensive odor of their new UPS also acknowledged that in their experience, new UPSs from most other manufacturers also seem to emit similar odors when first put into use, and have speculated that this may be true of most new UPSs nowadays that have been made in Chinese factories. I agree with this statement that most new UPSs from most manufacturers do seem to emit a noticeable odor for at least the first few days of service.When I first received my own unit and put it into use recently, it too started to emit a mild burnt plastic odor (the odor was most similar to the odor emitted by Bakelite plastic when drilled or cut with an electric saw) within two hours after it had been first put into service, and I was initially able to smell the odor at distances up to 4 feet from the UPS. . The odor gradually built in strength, to a moderately-strong level, over the next couple of days until, after about 3 days, I could smell it up to about 8 to 10 feet from the unit (which was sitting on the floor in my home office). However, I must state that by the end of the fourth day, the moderately-strong odor was significantly stronger than I have ever witnessed with any other brand or model of UPS, or with any other new electronic equipment (i.e., PCs, cable modems, routers, kilowatt-range DC-to-AC power inverters, kilowatt-range DC power supplies, solar charge controllers, battery chargers, etc.), and it was starting to permeate my small office area..So, at this point I decided to so something about the odor, because it was becoming quite irritating to me. I decided to do something to remediate the odor, that is, to neutralize it. I am a consulting scientist and engineer, and it just so happens that one of my areas of specialty is remediation and neutralization of odors (in industrial settings, landfills, waterways, etc.) by natural means (i.e., using natural methods, rather than using potentially-harmful "deodorizing" sprays that, in reality, try to mask odors with various artificial perfume-type scents or floral scents). So, due to my unique background and expertise, I fortunately had lots of resources for addressing the odor emitted by the new UPS at my fingertipsSo, this morning, after having decided to get rid of the odor, I opened two sealed 32 oz. packets of zeolite volcanic rock odor absorber that had been sitting in storage on a shelf in my workshop, and placed them near the UPS (I placed one just above the UPS cabinet, and the other on a desktop about two feet above the UPS and a bit to one side of it.These 32 oz. mesh packets of zeolite volcanic rock granules are marketed widely in home improvement stores, pet stores, and also on Amazon Marketplace as "odor eliminators" or "odor absorbers" (actually, the correct technical term is "odor adsorbers", since the rock granules adsorb odor molecules), and a 32 oz. packet of the granules in a breathable mesh bag usually sells for anywhere form $6 to $10 per bag.The way that these odor adsorbent products work is that zeolite, which is a naturally-occurring volcanic rock, is rather porous, and contains numerous fissures and honeycomb porosities in the surface of the rock granules, thus exposing a large surface area of rock to the air. And it so happens that the surfaces of zeolite exhibit a strong negative electrical charge. This negative electrical charge attracts and then adsorbs any odor or other molecules that are in the air that exhibit a positive charge, and it just so happens that the vast majority of odor molecules, including those causing the burnt plastic smell emitted by my rather new UPS, exhibit a strong positive charge.So, these positively-charged odor molecules are attracted to the granules of zeolite, and are then adsorbed into the numerous fissures and honeycombs on the surface of the rock granules, where they remain trapped.In my case, I emplaced the two newly-opened 32 oz. packets of zeolite odor adsorber in my office area at about 6 AM this morning, and within about three hours, the knockdown of the already-existing odor was about 90 percent. Within about 7 hours from the time of initial emplacement of the zeolite odor absorber (odor adsorber) packs, I could no longer notice the burnt plastic smell at all unless I placed my nose within a few inches of the air ventilation vents on the new UPS.[End of Addendum section offering hints and tips about managing the "new UPS" odor.]In closing, I want to stress once again that this noticeable odor emitted by my new UPS as it "breaks in" is not a showstopper, and it certainly would not stop me from purchasing more of these units.

I run a small business doing photo/video/audio restoration/up-scaling/conversion. Time is a premium and having capable, speedy hardware is a must. So I run an Intel Core i7-13700K, 32GB-DDR5-6400, three SSDs, ASUS TUF Gaming RTX4080 16GB GPU, SSL2 audio interface, Blackmagic Design Intensity Pro 4K, etc, etc, etc... all running on an amazing Super Flower PSU; plus two monitors and a large 65" flat panel TV. Every one of these things is plugged into this Tripp Lite UPS, specifically in the outlets connected to the battery. I mention this differentiation, because there are an equal number of outlets that do not use the battery - they are only surge-protected.So this unit has an LCD screen on the front panel with multiple readouts providing various bits of info - so you know what the unit is doing, and how much you're demanding from the unit. (Very handy feature, by the way!) One of those indicators is a 5-bars readout that lets me know how much power I'm drawing from the unit at any given time.At rest, under 0% computer load (meaning everything is powered on, but nothing major is processing at the time), the LCD readout on the UPS shows 1-bar in use. Impressive considering all the hardware I mentioned is all powered on and running (especially since the PSU is 850W alone).Incredible, however, is the fact that when the system is rendering video it draws significant amounts of power - pretty much every component in the computer is demanding 95-100% power draw - and this UPS LCD readout only shows three bars lit, with the 4th bar occasionally blipping every now and then.Amazing. This computer pulls considerable power under heavy loads like that (demanding pretty much all 850W from the PSU), and this battery backup has handled every instance with incredible ease, and plenty of room to spare. Color me impressed. WELL worth the money, as it has saved me from more than one power outage during this year's stormy season.If you've got devices that require significant power draws but also need the safety net of a capable battery backup, I'd recommend this UPS all day long.Kudos to Tripp Lite for another excellent, capable, quality product. Cheers!

Este producto realmente es de una calidad excepcional, la información que proporciona si es considerable y te enteras de varias cosas de tu instalación eléctrica.Por la parte del respaldo es el mejor, fácilmente soporte una pc + monitor + modem por una hora sin problemas (inclusive tienes la posibilidad de probar cuanto te va a durar en caso de un apagón con lo que tienes conectado)Donde hay un detalle (sin ser culpa del producto) es en lo correspondiente a la regulación de voltaje. Hay ciertos comentarios que se quejan del sonido y en parte tienen razón pero hay mas detrás de solo el sonido.Antes de comprar este producto hay que considerar, en primer lugar, el lugar donde lo vas a colocar. Si es en la oficina, tomando en cuenta el sonido ambiente, no existe mayor problema, pero, si es para la casa el sonido si puede llegar a ser alto. Ahora el sonido es parecido a una antigua PC o a una pequeña y callada aspiradora inalambrica. Dicho sonido se genera porque desde la calle se esta recibiendo un voltaje mayor a 130 volts o menor a 110 (y el aparato lo regula). Casi todo México padece de este problema, si tomamos en cuenta que el voltaje normal es de 127 volts.La solución que yo encontré fue comprar un regulador de Koblens que soporte la misma cantidad de energía que este no break (no sale en mas de 700 pesos) y asunto arreglado (ojo con conectarlo a un regulador que no soporte el voltaje de este aparato porque se puede llegar a incendiar el regulador).

This is a consumer grade unit that is rackmountable, made of hard plastic. First unit I got had a defective LCD screen that was scuffed up with some debris behind the LCD panel. The replacement unit was fine. However, as others have noted the fan on this unit runs 24x7 and is not suitable for a quiet environment. While not as loud as 1U server, its about as loud as a 90s/2000s fan cooled PC, annoying in this day and age when most computers are built for silence.Unfortunately this item is considered to be non-returnable or exchangable by Amazon - my unit came defective out of the box and Amazon was unwilling to offer an exchange. Very unfortuante - the return policy on this items is very unclear.UPDATE: I was able to escalate the complaint to Executive Customer Relations, they were able to issue a manual return for the item. Nevertheless, non-returnable items on Amazon should be flagged.

Based on another review I bought this UPS on the hope it would work on a generator. I have tried other brands but all of them react to every little fluctuations from the generator so often that they can never charge. This one has no sensitivity adjustments at all but it worked right out of the box. It almost entirely ignores load changes kicking in and out on the generator. It can charge up while the generator is running which lets me turn off the generator every so often. With other brands the battery can never get ahead.If TrippLite is listening I would love a battery expansion ability rather than forcing me to by a larger UPS. I don’t need a bigger inverter capacity, just more battery.

Disclosure and confession: I spent two decades reviewing UPS systems for several of the largest computer magazines, almost on a yearly basis, and got to know the players in the field quite well, along with their advantages and disadvantages. In almost all the reviews, Tripp-Lite would end up at or near the top of the list of products for their superb engineering, rugged design, and support. Over the years, I've bought quite a few UPSs for personal use, and the vast majority have been Tripp Lites.So, after buying another high-end computer with all-SSD storage, and suffering through five power glitches in a week of bad weather, it was time to buy another UPS. It was, quite frankly, a no-brainer. This was the unit I chose, based on several facts: I like to have extra capacity in the output, so I wanted at least a 1200VA model, the construction was extremely solid, and the price was competitive. I have not been disappointed. The UPS arrived next day (despite not paying for next-day shipment!), got plugged in, and went to work immediately.These are not the world's most attractive UPSs, but they are not ugly either, and they are designed to minimize heat and noise. The documentation is still (twenty years later!) mediocre at best, but all you need to know is on one or two pages, and the software (if you want to connect the UPS to your computer) needs to be downloaded and is, at best, acceptable. Other vendors have nicer designs, better-written manuals, and better software, but after comparing this Tripp Lite with older Tripp Lites and some other manufacturers' units already in my house, I still strongly believe the Tripp Lite is the best built and best designed unit. A very good friend is a protection engineer, and she took the unit apart and pronounced the engineering "excellent".If you want a space-age design and fancy software, then look elsewhere. If you want a UPS that is solid, rugged, reliable, and will be trouble-free for years, then this is one of your best choices. I have some Tripp Lites that have lasted close to a decade on the same battery, and have never seen one of their units fail (unlike some of the other UPS vendors). Extremely solid unit, and strongly recommended.

No les parece que este tipo de aparatos están un poco sobrevaluados? Soy solo yo? La tecnología y diseño de estos aparatos no cambia en años. Siguen ofreciendo las mismas capacidades (portección de coaxial y línea telefónica) y caracteristicas, en lugar de modernizarse a aparatos más "inteligentes". Las computadoras modernas, en especial las estaciones de trabajo o de juego, consumen fácilmente arriba de 800W. Ésta, está mal etiquetada en Amazon, pues es de 1000VA/500W, para una eficiencia del 50% (imposible que sea de 1000VA/900W, simplemente no existe en el mercado y creo que las leyes de la física lo impiden). Tripp-Lite tiene buena reputación, pero creo que están muy sobrevaluados sus productos, en Amazon al menos. No se si exista un canal más directo.
