The most valuable feature is the control. We started with PredictPulse at the very beginning. Eaton could not get it to function properly. We got to a stage where we said, "We're just going to ignore PredictPulse because we can't get it to operate and you can't get it to operate." Eaton did step up and they got it to operate in our Denver facility, and now we couldn't live life without it. It does add a level of comfort knowing that PredictPulse is telling us about potential errors before they happen. My preference is to keep it in ESS mode. It saves me a good amount of money. I've watched it work, flip back and forth with utility outages, and I've got complete comfort that the switching supports our critical load in a timely manner. We do drop out of ESS if there are severe storms in the area, or the utility is proving to be a little unreliable. That's simply because it concerns us when the UPS is switching back and forth so often. But it has been good. The footprint is also good. I always want it smaller, but I always want to be able to have more room to do things inside it, so I definitely understand that give and take. The good thing is that it fits in the same space as my old UPSs. It is a little bit smaller, but it's a little bit larger than the Toshiba that we have. But size is not an issue in size, at least in my implementation. View full review »

The two things that I like are the ESS, its related components, and the bypass sync, which means if there's a problem with the UPS I can mechanically wrap around it without going to static bypass. Eaton has one of the few units on the market that will do that. Because we're running mission-critical loads, in the event that I have a failure of the UPS where I can't go to static bypass before I go to maintenance bypass, I'm screwed. I risk losing the entire load. The Eatons allow me to literally go to maintenance bypass, which means paralleling on an alternate power source; the parallel is on, and then take the UPS out without static. So if I have a failure, there is a minimal risk of losing a data center to repair the UPS - and that has saved me at least once. I had an alternate vendor where I wound up spending about $180,000 in mitigation - they had to provide alternative power and staffing and a generator and all kinds of stuff - because the UPS had a fault and I couldn't go to bypass. With that other unit, there was a K13 contactor failure, which prevents the unit from going to static bypass. The alternate vendor's K13 contactor failure meant I could not go to static bypass safely. There was a 50/50 chance a unit would drop the load. On my Eaton, we had a component failure where we were unclear what the unit was doing. It was still maintaining load. I don't remember specifically what the part was, but it was one of the control systems. We were concerned that going to static bypass would have been problematic and they said, "But it's not an issue, you can go to maintenance bypass and then we can fix it." I came to find out it was simply a firmware upgrade and we were able to solve the problem. It was never an issue. We were concerned that if moved the UPS to static bypass it would drop the load. Because of the way the Eatons work, I simply could have gone to maintenance bypass and never have had an issue. That means I would have had a mission-critical room that I don't lose. One of the other key features that I like is ESS because it's cost avoidance. ESS is their Energy Saver System. What it allows the unit to do is run on utility power. They're smart enough and fast enough that, 99 percent of the time, if utility power is clean, the UPSs will let that power go to bypass power, let it go in, static bypass. What that does is that it allows the batteries to rest. Because I'm not draining the batteries constantly, it can sometimes double the life of the batteries. Normally we're replacing batteries in UPSs every three to four years, and five years is pushing it. I can now get six to eight years out of the batteries. That's cost avoidance. When you're looking at a million-dollar battery replacement, to be able to push that out three years is an enormous saving. That's on the VRLAs. Now, moving to lithium-ion that the whole dynamic changes. The reason I stay with Eaton is consistency and reliability, and also the service organization. To me, Eaton provides some of the best service out of any of the vendors I've ever worked with. I use Eaton service for my big iron. I do not use third-party maintenance for my big iron. One, Eaton's been very competitive for me. There have really been no cost savings to go to a third-party. But the other part of having Eaton fix them is that they have direct contact with the engineers. So if there is an issue with a unit, and I've had issues with units, the field techs call the Eaton engineers and the designers in Raleigh and in Virginia and talk to them. I get parts, I don't wait on parts. I don't wait on people to show up. These are critical devices. When they have problems, I need them fixed. I don't want to argue. And I don't have to argue with Eaton. They just come out and they fix them. They tell me what's wrong, they fix them, and off I go, I'm done. It's amazing. VMMS is a good feature. There are multiple charging units inside each UPS. For example, on my 9395 I have three to four charging units and the unit will scale down. Let's say I've got a megawatt of power. If I'm only running 200 Kw I can drop the charging units down and rotate through the charging units to reduce energy. They do all that. The 480 three-phase units are just big power. They're making them smaller. I'm seeing bigger densities in a smaller footprint. I think the industry is doing that on its own. Eaton's footprint is competitive. We would all like to say we want them smaller, but physics gets in the way. View full review »

It lets us know about any issues with the power. It is very sensitive to any surges or sags in power. We receive those messages and know when they are happening. View full review »

We have been able to get the data logs from them, which has helped us in dispelling some rumors (or accusations) that we have bad power by different vendors throughout the hospital. This has occurred several times for us. The logs have helped us a lot. The product is reliable. We previously used individual UPSs in every telecom room. By moving to Centralized UPSs, it is lower maintenance. We have just one guy (one of our supervisors) who oversees all the UPSs. He is the system supervisor. Through our Cellwatch system, which is connected to all of them, he is able to see what the status of all those UPSs are. Then, he is able to monitor the battery conditions. Because they are all the same, it limits the training and everything that you have to know between the different systems. This has helped us on the manpower side of things by lowering the manpower needed to maintain them. We like the touch screen functionality. I have not personally had a lot of experience with it, though my supervisor has. He likes to be able to navigate through it, while our older GE system does not have this functionality. The GE system is very plain with just a few buttons, and it's very difficult to get information out of it. Eaton's touch screen functionality was something that was very quick to impress everybody with its ability to get to everything. We use the touch screen functionality to monitor for battery life, the amount of usage that the UPS is being supplied, and how much energy is being supplied through it for our backup time period. We even look at the incoming power to see what the condition of our incoming power is. Therefore, we are using it more as a tool to monitor feeding power, not just the power that of what it's feeding. We use it to see how we're balancing our loads across circuits, because we're using 240 UPSs. Thus, we are trying to balance the loads when splitting the power down to 120 volt circuits, keeping it balanced across the legs of the power. We run dual battery bank systems. Therefore, if we are doing maintenance on one side, then we can maintain the other side and still have the battery backed up. In our data center, we have redundancy in all of our racks. When UPS feeds one half of the rack, the other feeds the other half of the rack. We have dual power supplies to everything. We have a lot of redundancies because of that. Luckily, with Eaton dual Battery Cabinets, we can maintain the systems at all times (short of a transformer issue), even while we're doing the maintenance on them. Our IT department loves this, because we don't shut them down at all. View full review »

We like the ESS, the Energy Saver System. It saves us on our electrical bill. That's a good feature. There's are two parts to that. By using the ESS, we get a rebate from the local utility of about half-a-million dollars. The actual savings over the year are probably only about $4,000, but I don't know if that is per unit or for the room where we did the study. It provides us a moderate amount of electrical savings throughout the lifetime of the unit. We also like the modular system and the easy-to-read display. The touch-screen functionality is easy to read. There are tabs at the top and there are statuses at the top, graphics that give you a quick glance. We use the touch-screen for metering, to make sure the input and output meters are good. We also check alarm events and system history. Those are the things we usually check the most. In addition to the display, there's a color methodology to the front display on the front cabinet. There are green, red, or amber. They provide quick graphics to understand if we have a real problem or a minor problem. The Eaton UPSs are user-friendly. View full review »

The most valuable feature is that they don't go down. We haven't had any other UPSs in this location, but we've had Chloride UPSs at other places and they didn't do so well. The touchscreen functionality, being able to go to the UPS and look at readings, etc., is pretty intuitive. It's user-friendly. It's useful to know where you're at. In terms of the unit's footprint, it fits well, considering its functions. We also use the UPS Service Plan. We have a contract with them for that. It's very good. We use it all the time. We have to do PMs (preventive maintenance) on the UPSs throughout the year, as well as on the batteries. We've got enough units that they'll bring an extra tech in. I, myself, don't do anything with them, other than monitor them onsite. They are pretty much a fixture, like a piece of the building. They're in, they run, they do their thing. And if we get an alarm we call a tech and he comes out and he takes care of it. View full review »

The monthly reporting is one of the most valuable features. It gives us an overview of the last month of its operation and we can see trends that are showing improvements or where availability and performance are decreasing. The visibility the PredictPulse service provides into our UPS equipment through the reporting is very good. It gives us very high visibility. We can go into the card and look at every parameter, all the settings, all the values. There are several tabs we can look at. We get a very good understanding of what the unit is doing, all remotely. It's very good. I like the UPS touch-screen functionality as well. It's good. View full review »
