Tripp Lite SmartPro 120V 750VA 600W Line-Interactive Sine Wave UPS, 1U Rackmount, Pre-installed WEBCARDLX Network Interface, USB, DB9 Serial (SMART750RM1UN) Black

Pretty basic unit. Hardly any indicators or controls. But it does its job, and doesn't go into a fault mode every time there's a power hiccup like the CyberPower unit it replaced.

At $150 or thereabouts, this UPS is perfect for a small business server room. I purchased this device to act as a surge protector and UPS for a Dell PowerEdge R210 rack-mount server, PowerConnect 2016 powered gigabit switch, Cisco RV220W gateway router, and an external RAID enclosure data backup device. The SMART500RT1U appliance comes with a small instruction manual that explains how to install and mount the hardware. It is very straightforward and it is worthy to note that the manner in which this device mounts to the rack is such that you do not need a tray to ensure it is secured (the mount point is at the device's center of gravity).Plug in the power cord, attach your devices, and power it up. It is really just that simple to get it functioning as a UPS with voltage regulation and noise protection. If you are like me and have had an electronic device fried by power fluctuations (I live in Florida and lightning storms are a daily occurrence), the $150 is a small price to pay to insure valuable equipment and data. In addition to the standard protection, this particular model also includes software and a USB connection which allows it to send a signal to your server telling it to shut down in regular order when the power goes out. This is important because these types of battery backups only last a couple of hours under medium to high load capacities before they too run out of juice and you have a sudden shut down which can cause damage and data loss.The last point I would make is before you order, make sure that you add up all the wattage and VAC requirements for everything you will attach to this device. This particular model supports 300 watts and 500 VAC. At max load, the devices I've attached to it fall just short so my setup should be fine. However, if you have a more robust server you should be looking at the higher capacity models in the 800 watts / 1000 VAC or above range.As a side note, Tripp Lite makes similar models that are non-rack mount for different setups, and this particular model converts to tower mount when you attach the arms in a different way. Good job, I'm very happy with this guy.

I’m an APC guy, but I needed a shallow depth rack mount unit for this install and they didn’t make one. I settled for the cyber power. It’s a solid “meh”. It’s priced high in my opinion given the short battery capacity, but it’s only powering a single PoE switch and is good enough for short outages. For the money, a digital display with load indicator and such would be expected. This just has a few green lights that serve little purpose. Even the cyberpower SOHO units that cost half as much have basic digital displays displays and higher capacity. It you need a compact rack unit, this is about all there is so there’s that. If you have full depth, look at the APC models and you won’t be disappointed.

I bought this Tripp Lite 2200VA RM unit to replace 2 1500VA RM units from CyberPower. The CP units were virtually silent, unless a power outage occurred, then alarm beeps and fan noise were enough to raise Elvis.The bad:After installing the this Tripp Lite 2200VA unit, immediately after plugging it in, it started squealing and buzzing. This was not the fan or an alarm, this was the charging circuitry. It sounded like the caps were boiling away and about to have a critical failure.This is in my home office, and you could here it buzzing in the living room, which is 25' down the hallway.Unplugging and letting it go into inverter mode made the sound go away. Same if you did a battery test. Plugging it back in, or after a batt test, the very loud squealing and buzzing returned.Called Tripp Lite tech support and they tried to convince me this was "normal". He said I had purchased a data center class product and noise was expected.1) Data center UPS' would be something much larger, like 5000VA or a dedicated UPS cabinet, not a rinky dink 2200VA UPS.2) It's marketed for small office and home office use, where noise would be an issue.3) The Tripp Lite tech didn't sound like he cared if my house burned down.After working in IT procurement for 25 years, I have never, ever heard a UPS that was this loud. And there was definitely nothing normal about it. The rude and disinterested tech left a bad taste in my mouth, too.The good:Great rail kit included, easy and quick to install.Liked the LCD panel and how easy it was to change settings and test the battery, with multiple levels of dimming. You could also set it to continuously scroll through the various statuses.

Works well and easy to setup. Would be nice is the rear rail mounts were included however like their equipment over others. What others say is in line with this product. Will probably be using more of these in the future.

Great features and capacity for price.

Para ver lo de una garantia por que el equipo que compre ya empezó a fallar muchas gra cias p

works fine does what its suppose to do
