Wow, 12 years. That went quickly. I started watching your channel 11 years ago, when I was 7 years old.

[@Maxxarcade]

That's a sweet unit! I've been saved by my UPS systems enough times that they've all paid for themselves.

[@uxwbill]

My own UPSes have definitely done the same! The "star performer" award goes to an unassuming Smart UPS 420. (It's the one that whistled like a teakettle in an old video.) Someone hit a power pole and that killed all the electricity around here. For an hour and a half that thing carried the load of my DSL device and wireless router, and it showed no sign of stopping there. (I didn't need it to do any more, but it soldiered on for some time after that, until the lights came back on.) The SU420 had a hard life before it came to me. Someone was trying to run a rack of servers and networking gear from it. Only rarely did it not complain bitterly of being overloaded. And yet the battery was still good when I got it! I have amassed several APC units with extended runtime capability and even a few battery boxes. I'd love to have not only a proper rack for the rack mounted ones, but also the money to put new batteries in them.

[@Maxxarcade]

@@uxwbill I remember when we lost power on a really hot day, back before we had a generator. I shut down my computer and ran my big metal box fan off my old Smart-UPS 1250. Fell asleep and woke up 2 hours later, and still had 2 bars on the battery gauge. The cheap little Back-UPS units are really handy too. I've plugged household LED bulbs into them and carried them around like big flashlights. I also found out that those will blow up if you store them with the cord plugged into itself, and install a battery before remembering to unplug the cord. Inverters don't like to be backfed by themselves it seems :-)

[@uxwbill]

@@Maxxarcade Generators are great fun. I might be talking about a cheap one I found in an upcoming video. Usually the power here is quite reliable, but it was cheap and I am always curious. I have wondered at times what the Back-UPSes would do if plugged into themselves, but I've never wanted to possibly trash one by finding out. (Seemingly the Smart-UPSes will detect this, but again, I'm not trying it.) Do you remember what dies in the aftermath? For a while I had plans to build a basement emergency lighting system with a cheap Back-UPS, some CFLs, a very large deep cycle battery and an HVAC fan relay. The idea was that I'd plug the relay into an unprotected outlet. When the power went out, it would no longer be held open. The UPS would come on at the same time, and power the lights. It never really worked out. The big battery turned out to be junk and I never finished the project. A while back, I took the last vestiges of it down.

[@Maxxarcade]

@@uxwbill The Back-UPS 500 that I accidentally plugged into itself ended up blowing the inverter outputs rather violently. The beeper made some funny strangled noises until the destruction stopped, but of course there was no output anymore LOL. I've been thinking about making some sort of emergency lighting setup too. With the low power consumption and high brightness of modern LED's, It should be possible to get a lot of run time without needing huge batteries. I still remember those funny looking old lights with the wood grain cabinets that had a pair of 6 volt bulbs on goosenecks sticking out of the top. Times sure have changed :-)

Induction motor's are typically "wired" for frequency and voltage. Probably had excess current draw when it was turning too slow. Likewise if you ramped it up to 65-70hz you might get a drop in current draw.

Tripp Lite is a company with an interesting beginning, and has a hint in their name, and it has everything to do with taking a trip via automobile

Trippe (they later dropped the "E") was a family name, and their first product was said to be a light for automotive use.

[@craignehring]

@@uxwbill Yes automotive accessories, I may have forgot about the Trippe part. I think they had a simple trav-letric buzz box inverter for electric shavers

Merry Christmas William, thanks for all the videos, all the best for 2020.

[@AverageJoe2020]

Hi Bill, running a 60Hz transformer on 50Hz (for example) will make the transformer run hot, something about the lower the frequency the more iron is needed for magnetic coupling- so you will find that RF transformers need little or no iron in their core, Best regards, J.

[@JohnSmith-xq1pz]

The real milestone of interest is the 100th "SMOKE TEST!!!"

[@IfYouLikeGoodIdeas]

In some ways, this UPS reminds me of the much more common "SmartPro" ones we recently purchased at work. Those are only line-interactive, but they are constructed on a very similar chassis with some of the same features (switchable loads, serial/USB connectivity, management card slot, EPO, etc.). If this one works like those do, and you can't find the network management card, you can do just about everything the card can do using a PC running Tripp-Lite's "PowerAlert Local" software. In particular, it can act as an SNMP agent on the UPS's behalf, allowing you to connect other management systems to the UPS using the PC's network connection. Supposedly it will even let you connect multiple UPSes to the one PC, though I have never tried that.

[@uxwbill]

Sooner or later I'm going to get ahold of a management card for this one. While probably only a coincidence, the opening for such looks very similar to those seen on Eaton's bigger UPSes.

[@tylercasey7950]

Hi, I hope you're doing well. Maybe you will be back sometime. I always look forward to your videos.

[@Kristjan10a]

With a VFD if u go lower with 3 phase motor it will heat up and needs to have an external cooler, cause motor fan cant cool it cause it runs slower. If u run it faster the motor fan will cool it fine but bearings might fail sooner. I might be wrong but this is what i have seen at our workplace where motors are run slower then mains frequency (50Hz)

[@joshstacey497]

We have something similar in our server cage at work, don't recall the brand right off hand, but think it is UPS brand, red lettering comes to mind. A couple of years ago I had to replace one battery in it, so I replaced all 3 batteries. Since then no issue with the servers rebooting.

[@uxwbill]

Red letters would strongly suggest APC, which is what practically everyone buys. Cyberpower seems to be the next most common thing. Tripp-Lite isn't too far behind. It's rare that I see anything from Eaton, but even their consumer grade stuff is top notch: they have excellent battery charging circuits. Liebert/Emerson/Vertiv products are even rarer. Two of the only ones I've ever seen are both in my possession. They're basic consumer grade (500 VA or so) models, but as with Eaton's product, they appear to be quite well thought out.

[@seanstechworld]

I work with systems in datacenters and those are staples for us. Excellent UPS units. The newer ones have a bigger display. That one was discontinued in about 2015 in favor of the units with larger displays. I do not have a model of the newer units on hand at the moment but I do know that those units showed up on the market in about 2011 and Tripp Lite rode that cash cow as long as they could. Nice score there man. Enjoy it

[@vwestlife]

I'd call it "Tripp-Heavy".

[@uxwbill]

The lack of a heavy line frequency transformer helps a lot.

Cool a computer related uxwbill video, and more on the way!

[@Bandicoot803]

As a service technician I come across various appliances for quite a lot of companies. I have also noticed that hence living in a country where 50Hz is standard, some machine designers have programmed their VFD to run the motors on 60Hz for whatever reason. Let it be a 7.5kW water pump or a freezer's compressor. The reason for this is yet unknown to me to this day. What concerns your box fan, my assumption is that the capacitor size has been designed for that particular motor to run at an ideal angle of 90° at 60Hz. Running the motor woth a higher or lower frequency outside than it has been designed for results in poor motor startup, and potentially, running speed. Worst case: The motor can actually stall at too high frequencies. Note that what I've written about the capacitor doesn't apply on shaded pole motors.

[@uxwbill]

I'm not sure why the designers would have done that either, unless perhaps a 60 Hz motor was cheaper or they just decided to use the same part in every model. Unless there's something I don't know, it wouldn't matter since the VFD is feeding it 60 Hz. The box fan doesn't have a capacitor. It's just a simple shaded pole induction motor. I was thinking of trying some capacitor start/run induction motors at 50 Hz just to see what they'd do.

[@Plu54f0x]

That Tripp-Lite is interesting. I'd use it to smooth out generator power in a prolonged outage event or a remote location, providing the unit would happily run from a generator.

[@uxwbill]

It would be excellent for that application. Its charging circuitry won't care in the slightest about dirty incoming power. I should have tested it with my variable autotransformer to see just how far down the line voltage could go before it was unable to charge the battery.

[@dnb5661]

Here is something interesting that I noticed. The system font on your scope-meter, is the same font that is used for old IBM, and compatible computers.

[@ENB2002]

[@reddragon27284]

Just put in 3 3KVA Eaton 9130 online UPSs at work, they’re really good for datacentre use but because the inverter is always running so is the fan so it’s no good for quiet environments. Not a problem for my use.

[@kazzooka]

The squeak or squeal you hear could be from a Coil whining. When you put current through a wire it will vibrate, you may just have one that is in the audible range. The other possibility is a Capacitor that maybe failing. Gas coming out the little vent holes making a whistle. I would think you have heard that coming from a few switch mode power supplies in computers you have worked on. The Best Power Ups models that used "Line Interactive" always had a big Ferrite core transformer that created a big electromagnetic field that would act as a line conditioner. This Transformer also isolated input from output. The other thing it did was allow a "flywheel effect" when the power failed. The Inverter would have plenty of time to come on line before the field collapsed. No need for the complicated double conversion. Also having the big transformer allowed winding's to buck or boost voltage before having to use batteries . You do know that you don't have to "poke" the buttons to change parameters. Most of these units had software applications you put on a PC and connected by serial cable. If I recall the Best power used a null modem cable. Good use of an old windows computer perhaps? Thanks for the content, and blessings to you and yours.

[@uxwbill]

I do have familiarity with the concept of coil whine. What surprised me was the nature and frequency of the sound. I'd have expected it to be much lower in pitch, constant, and more of a soft hiss or growl like others that I've heard. Perhaps I did a poor job of expressing my thoughts. It wouldn't be the first time. :-) I'd hope that something this new wouldn't already have bad capacitors. Someone once offered me a Best 5 kVa FerrUPS if I'd just haul it away, but I turned them down because I didn't have a place for it, and I thought it might require three phase power. It probably used the technique you're describing, which I believe is similar to that employed by ferroresonant line conditioners. (I've got a few of those, from General Signal Sola. All still work just fine, and they definitely aren't brand new, as they claim to be for use with minicomputers.) The little Best Power Patriot that's seen in this video seems to be a very simple beast. Near as I can tell, it has only simple signaling support. But there are a lot of things I don't know about it, and would like to find out. (In particular, the bank of four DIP switches inside has me curious as to what they do, or even if they are for end users to operate.) Yes, it's true that I could haul a computer outside, hook it up to the UPS and even install vendor provided software on it to operate and adjust the UPS. That's a much bigger hassle than just tolerating the shortcomings of the control panel, which really weren't that serious to begin with. It's also not guaranteed that the management/monitoring software will let one adjust every operating parameter of the UPS. If I went without any vendor provided software, I don't happen to know what "language" Tripp-Lite devised, so that I could communicate with it directly over the serial port.

[@kazzooka]

@@uxwbill If remember correctly the "Dip switches" were for either selecting a sensitivity range for incoming power or changing communication modes. I think it mattered which model it was. (Been way to long). Things like laser printers or Microwave ovens being on the same circuit as these UPS's would cause these units to constantly go to battery. They would make the "line power" unstable and noisy. You could adjust for that on the smaller units. The other use was for changing communication from RS232 to an Extended Signal mode on the db9. Had to do with if the thing would two way communicate or which pins open/close connections to shut down the unit. Remote shutdown was available on these. Pretty handy if you were far away and needed to do that. Think of Firefighters spraying water on a active UPS--shocking! Mains go out the UPS goes on. To communicate with the Best unit without the Checkups software you can use Windows old Hyper-terminal app with the 8 bits, none parity, 1 stop bit settings. There were three levels of Passwords; User, Service and Factory. There isn't a parameter you cant fiddle with at your own peril at the Factory level. Very few at the User level. Getting your hands on the documentation of commands maybe difficult. (Some dark corner of a inaccessible storage shed in a sub-basement located on another planet) The Ferrups line of UPS came in 240/208/120 volt single/double phase input. 208 was a odd beast with a 88 volt and 120 volt line input. You really only had 208 to use and one phase of 120 as output. Not a really balanced load. What do you do with 88 volts? The Unity series were the three phase UPS's. Thanks for the Reply Sir!

Hey UXWBill, hope all has been well. I have recently taken up freelance computer repair myself and I was wondering how your experience with that has been recently.

[@seanstechworld]

I actually know what that noise is. I have installed quite a few of these units. It is the inverter ramping us and some of the components make a coil wine type sound at startup. Nothing fatal.

[@KuntalGhosh]

The "transformer less" design is lot better than the older design. It actually still has a transformer but it is a very small one. These are doing dc to dc conversion like an smps. So it oparates at very high frequency. Reducing the size of transformer and coil required. Most ups's using huge transformers are now made of aluminium and their size is small , so they get very hot and not suitable for extended use application. If you increase the size of the battery the transformer melts. So this new design of dc to dc conversion is much more efficient and they use copper because the length of wire used is not much. And in online ups they never had low frequency transformer because it would make the efficiency of the unit worse. And make it bulky

I'm not sure how much trouble a 10 cycle difference would make, switchmode power supplys just don't care, maybe large inductive/capacitive loads may show a difference but reactances that big are not often used.

If there are any kind of electronics recycling operations in your part of the world...get to know them. You might even want to talk to the owners of more general scrap and salvage yards. Sometimes the stuff that shows up is absolutely amazing. A UPS with dead batteries is worth nothing to most people, and many of them are replaced as soon as that happens. That's how I've come to have almost every unit I've got, and many are quite high end.

[@HarleyBadger]

You can run a 60Hz motor on 50Hz with no problem (usually.) However, running a 50Hz motor on 60Hz will cause it to draw more current without going a whole lot faster. The squeal when you power the UPS on is the inverter powering on. Also... infinitely jealous! :-)

[@matthewbestdfghy]

Japan uses 100v AC and standerd US electrical plugs and sockets. I have heard of people using Japanese fans in the US with no problem.

[@junker15]

Japan is also a dual-frequency country. West (Osaka) uses 60Hz; east (Tokyo) uses 50Hz. So the appliances in Japan are usually made for the usual 47-63Hz.

[@uxwbill]

I have a variable autotransformer of Japanese origin that was designed for 100 volts (at 60 Hz). It's very old, probably dating from the very late 1940s (!) or early 1950s. It works just fine (though the built in meter reads incorrectly, as you'd expect) on 120 volts AC.
