Tripp Lite SMART2200NET 2200VA 1700W UPS Smart Tower AVR 120V XL DB9 for Servers, 6 Outlets

Generally, the umpire gives the batter 3 strikes and you're out, no? Right u are!And that's the story with this DumbOffice 550. I've gone through 3 of these clunkers, and every one of them is defective in one way or another.I will say quickly, and without further delay, that Tripp Lite honored the warranty policy on one of these that qualified. Fortunately, that particular unit completely died. The inverter totally failed, or I suspect it was the inverter. But before discovering I had a major failure, I went and spent the money for a new battery, thinking, "Gee, this thing can't have failed, could it???" The new battery did nothing to the good. New battery, old battery, same result. Unplug the unit from the AC service, and even with NO LOAD, the red LED on the front panel, indicting OVERLOAD would come on, along with the buzzer, and after 4, 5 or 7 seconds, it shuts down. Repeat the process as many times as you like, same result.But perhaps the most troubling aspect of this situation was Tripp Lite's complete lack of interest for examining this unit to determine why it failed. I offered to return the failed unit to Tripp Lite, AT MY EXPENSE, and they said they did NOT want it returned. This would have been an easy packing job, since I had the replacement unit's packing materials. The failed unit is the exact same model, meaning, the failed unit will fit in the replacement unit's packing box perfectly. No hassle. Just pay the UPS man and be done with it. Tripp Lite DIDN'T WANT IT..What are these people thinking?Ok, that's enough on this one. No one likes long reviews.The warranty replacement unit, referenced above, hums and buzzes, and switches over to the battery frequently. And it doesn't matter which way you twist the SENSITIVITY ADJUST control on the back. And like the other one I mention shortly, it runs quite hot, even when not doing anything, just being plugged in but not delivering any load, and nothing connected to it being turned on. Slap the cabinet one way, then another, bang the top, and sometimes one can get the humming to quiet down. But I'm not going to scream too loudly as #2 still works, with the above shortcomings. I have it connected to an eMachines W3644, which is a penny-pincher computer that has only a Sepmron LE-1200 CPU and only one plug-in card, a modem, so it doesn't represent much of a load. With just this eMachines and a small 19" Asus LCD monitor, when I pull the plug for approaching storms, the battery holds up for only 5-7 minutes-- sometimes perhaps a tad more. That's not much of a load, and not much duration time. But it's better than nothing I suppose.And the 3rd one, it's behavior is just like the description above, with the same annoying "switch to battery" occurring often. In fact, they are such a pain I have to just turn them off when going to bed so the buzzer doesn't come on and wake me up, which both have done often. This 3rd unit I use as a backup for the TV, VCR and DVD burner. Very same SmartOffice 550, and as with the others, should be called the DumbOffice 550. Or maybe the BuzzBox 550, er, HumBox 550?Every one of these has a bug-a-boo about it. But I know Tripp Lite can do better because I have yet one more Tripp Lite toy here, a UPS device made back in 2000, which goes by the trade name of "Internet Office 500". That's right, it's now 2010, and this Internet Office 500, long discontinued I suppose, is still rendering outstanding service, TEN YEARS after purchase. I've only had to change the battery. None of the aforementioned headaches discussed above apply to this Internet Office 500.So what has Tripp Lite done between the Internet Office 500 and this SmartOffice 550? Some corner-cutting, cheap and dirty mistakes, and they should be ashamed. Dear Customer, er, potential customer, look for something better, this is a troublesome unit.3 out of 3 and all troublesome, is unacceptable. One of these was purchased here thru Amazon, the other via [...]. Doesn't seem to matter where you buy it, it's trouble.

First off, this should be noted to be a continuously active fan, not passive. As it's commercial-grade, the fan is not quiet either. Really the noisier of the pair with my Fractal Design Define R4 case, but it has an AWESOME feature set that I've been looking for off'n'on for nearly a decade.This is a UPS that has sine-wave output for both wall socket and battery outputs. This is a *must* due to the residual deterioration that comes with modified sine wave outputs. Not all systems react well with modified sine wave outputs either.As my area's power grid is rather dirty due to the elements on top of how all of my home's circuits have issues with surges and brownouts as appliances activate and deactivate, this is a *required* item for my needs. I could get by with power conditioner, but the periodic momentary black-outs necessitate a UPS.=-=This unit is HEAVY! It should be noted that the ship-weight is 48lbs of dead weight.=-=So why did I go with this one?* ALL of my needs/wants were met (outside of the fan's dB) and current/past interactions with Tripp Lite have been a pleasure. They have a very prompt and knowledgeable US-based tech support. :)* I'm mining cryptocurrencies and require a higher capacity UPS due to the dual video cards.---I'm going to be building a sound-dampening cover to slide over the top and sides as well as baffle the air flow and fan vibration without restricting the air flow. This may also possibly include filters for the side panels so as to restrict hair/fur/fibers due to the planned floor-level intakes. For now, I'm using three case side-panels to provide a minimal baffling of the sound.After the warranty is over, the fan is going to be replaced with a sub-20dB long-life fan.

This is a very easy to use back up power supply. I plugged it in to my iMac through the USB port and it was automatically set up. It runs in the background and has a long battery life.We have lots of power outages here, and the real nasty kinds where the power goes in and out for several seconds before it finally stops. I have had computer power supplies blown from these spikes. One time our house (Metal roof since we catch the water in a big water tank) took a direct hit from a lightning bolt. (The power was out for 8 hours since it was a bad electrical storm) The house was hit so strong that it blew the power fuse on the power pole. Since this strike was right on the house it was very serious, my Tripp Lite back up power supply clicked off. Unfortunately, that also turned off my computer, but when power came back up, the Tripp Lite came back to life and all my electronics where fine. Without it, they would have all been damaged for sure.Other times we have had surges and power outages where my computer didn't even notice. And since I have VoIP I also keep my cable modem and router on this back up power. So, I was able to call the power company in the dark on my phone (I have a simple phone that doesn't use an electrical outlet) then turn off my computer safely. I left the power on the cable modem and it stayed up for hours. Until another lightning strike took out something on the cable lines somewhere...

Works just as intended. Was here 2 weeks quicker than my regular suppliers.

pecfect over my expectations.

I have three of these UPS units now and they work flawlessly. I prefer this small vertical black box format, which takes less floor space and have all the connections in the back. I use these for my TVs and video and audio systems.

excellent

Espectacular
