WSN power source selection

Page 11 of the WSN-3212 States guide:

"The unit automatically detects what power source is connected and switches to this source. The device is not designed to provide battery backup in the event of loss of external power. If the two are related, the functions of the external power supply input device, but may require a reset device when the external power supply is cut off. »

I see the expression "MAY require reset" by suggesting that he might or might not.  It is possible, but has not guaranteed, that node continues running (although on AA) even after AC is disconnected?

Thank you

Garrett

Hey, Garrett,.

As stated in the manual of the product is not designed to backup battery.  In the case you described, the node will likely restart.  When the external power supply is removed, the voltage will drop momentarily causing the node to reboot.  There is a chance that the node will happen without problems, but it is not guaranteed and I recommend it on your system for this design.

Let me know if you have any other questions!

  • Power supply selection guide

    This MOD can make a post-IT.

    Here is a general guide on how to select a power supply for your HP desktop computer.  The majority of the standard ATX power supply (PSU) must fit in an envelope of HP.  The exception would be a slim casing or the esoteric Merle.

    Looking for a certification 80 + on the PSU to save electricity.  A PC is normally idle or operate at low load 75% of the time.  Therefore, to find a power supply which is more effective in the range 50 - 90W.  A power supply 80 + 350W reaches the level of efficiency of 80% at the exit of 70W (20% of rated output).  The output must be greater than 140W to achieve the same level of efficiency of a PSU of 700W 80 + equivalent.  So choose a power supply that is rated at 25% more than the maximum load of the ACTUAL spending of the rig you will save more of $ on electricity.

    A modern PSU is designed to achieve maximum efficiency between 20 and 80% of the nominal power.  Running a power supply above 80% charge level will result in excessive heat, noise and premature failure.

    A platform Nvidia GeForce GTX 280 (1024 MB of RAM) will rely on 350W max to the wall.  Taking into account the effectiveness of a block of power SUPPLY 80 +, the actual load on the power supply is only 280W (350 x 0.80).  To calculate the required power supply, multiply the actual load by 1.25 (25% margin).  In this case we only need a PSU 350W (280 x 1.25) to run this GPU.

    Let's apply what we know of a rigging of Radeon HD 4870 (512 MB RAM).  290W max to the wall.  Actual load is 290W x 0.80 or 230W.  Now, apply the 25% margin rule and we come to a requirement of 290W PSU (230W x 1.25).  Even if we apply a safety margin of 50%, the power required is always under 350W (230W x 1.50).

    There are no overspec need the power supply by 50%, unless you run your PC up 24/7.  Don't forget that there is a huge variation in the quality of the PSU and side.  Maybe a good 500W PSU is not able to provide as much energy as a quality 350W.  Antec Earthwatts/NeoPower/TruePower and Corsair Seasonic are widely available at several American retailers of quality units.

    High-end power supplies number will need additional power supply PSU in the form of one or two 6/8 pin plug GPU.  You can buy an adapter to convert a molex 4pin to plug 6-pin power of GPUS.

    Hi Nautsj,

    You need to open your PC and measure the physical dimensions of your diet. Here is a list of the things to consider:

    1. technical characteristics
    2. the total power - important
    3. amperage 12 + v - important
    4 modular - is not required, but I like the flexibility
    5. guarantee
    6 i7 and SLI ready
    7. energy efficiency
    8 cost
    9. size - standard ATX PSU is 5.5 "by 5.9" by 3.4 "give or take a few tenths
    10. a single + 12 volt rail is a better choice.

    www.Newegg.com has many choices of power supplies. Corsair, OCZ, Rosewill, Thermaltake...

    The typical EVGA GTX 570 in 9 "long.  The adjacent slot on the PCI-E x 16 slot must be vacant.  Open your PC and do some measures so that you know for sure if the card fits.  According to me, it will fit.

    For what is a PSU, Corsair CX600has very little growth, but the Corsair HX650gives you plenty of space to grow.

    I use the HX650 in two PC.  It is a modular model in order to have better options with the selection of cable.

    "How-to" HP articles should be useful.

    TIP: When installing the power supply, unlock the scanner and slide it forward to facilitate the removal and installation of the new power supply.

  • HP pavilion p6520y power source

    Hi, quick question about upgrading my video card.

    Diablo 3 will be out soon and I would like to upgrade my video card in the game before that. Ive been looking at this map here, http://www.newegg.com/Product/Product.aspx?Item=14-130-609 & SortField = 0 & SummaryType = 0 & Pagesize = 10 & pure...

    and on sound reviews say that it is no necessary additional energy source. But according to the HP website, he states that out of my diet is 250W computer configuration, and the video card requires 300W. Should I get a power supply upgraded to run this video card, or any other video card? I don't want to buy a power supply if not unnecessary, but I would also like to play D3 in graphics the less 'high' mode. Any help or suggestion for video cards would be greatly appreciated. Thank you!

    -Mike

    Mphillips5015, welcome to the forum.

    Yes, you will need to upgrade the PSU to run this or any other video card more recent intermediate level.  If you upgrade to at least 500W, you can even buy a better card.  I love the Corsair and OCZ PSU.  They are made with the player in mind.  They provide clean and stable power for your system.  The PSU is the backbone of the computer.  Therefore, it is not the place to save money.

  • NEITHER USB-8451 with external power source

    Hi all!

    I try to understand for 2 days now why my USB-8451 gave me a 301740 error: line SDA or SCL or both are in poor condition, or there is no pull-up resistance.

    I try to change a multiplexer channel in order to obtain a measure of the temperature of a sensor. I checked my SDA and SCL lines, thye are both in top condition and I have 2 resistors to pull up with a value of 10K.

    The only change with my older circuit, is I use an external power supply for my chip and a PCA9543 (texas instruments) MUX to select the sensor I need the data.

    Any who have encountered similar problems?

    OK guys,

    Apparently, the ground of my usb-8451 was not related to the land of my diet, it doesn't yet but my components react!

    Hello

    When a Li-ion battery loses a percentage of it's load capacity, you can see inconsistencies as you describe in the for laptop charging circuit.

    Typical life for a Li-ion battery is 1 to 3 years, depending on how it is used.

    I would recommend that you create a report of the battery to check the status of the battery. Perform the following steps.

    1. go to Start / all programs / Accessories. Click on the command prompt and select run as administrator.

    2 in the command prompt window, copy / paste the following command.

    powercfg-energy-output %userprofile%\desktop\energy-report.html

    Press ENTER.

    Wait for the command to complete (usually about 2 minutes).

    This create a file named energy - report.html and place it on your desktop.

    3 go to your desktop and double-click the file to open.

    Scroll to the bottom for the battery: battery information section.

    You will see:

    Rated xxxxx

    Xxxxx full last Charge

    (Where xxxxx is a number)

    The source being different devices, you can connect multiple devices to the screen, but not at the same time view. So you might have A device connected to the DP, device B connected to DVI and switch between them using the OSD Menu - the input Source.

    already reset smc, just update macos what to do next? Thanks for help

    You can choose to wait until your computer is open to the public

    and diagnostic tests performed, if this issue does not affect

    any software update or upgrade; because the device must be

    provided with a steady current while the software is installed. In particular

    with the Mac App Store and if you use a wi - fi connection to access the internet.

    Usually the SMC or system management controller, if reset in one

    effectively, should also be a reset of power management,

    If the process is not successful, there may be other problems in

    the charging circuit which will have an impact on the whole Mac.

    One of the elements which can manifest a strange behavior is whether or

    When the "MagSafe DC-in Board" has become defective. It can

    show no battery and always run the Mac. It may also fail totally in

    a way without notice; that can't end well if use it right now.

    Visit a regular on an Apple store with genius, or an authorized

    Apple's Service provider is recommended; to get a practice notice

  • Desktop Pavilion slimline s5623w installation of card firewire but how to connect to a power source?

    First of all, I HATE THE SLIMLINE MODELS. NOT WORTH THE MONEY! got as a gift and thought, I could replace 2000 mine thinking it was cheaper because the technology is less expensive.  BIG MISTAKE!  sucks it first audio, so I had to buy branch pregnant even hear, I use the old speakers from my other computer to my mp3 player and it rocks!  then I find not modem phone fax so I buy a usb phone modem, but wishes to make all kinds of mistakes.  now I have these old camcorder videos I want to run through this program a and discovered the firewire card was too big and did not yet align.  on my fourth product now and this one fits.  Yes! but now, we must be connected to a power supply inside the computer? where is he? has a white connector with pins on it but no wires and where is the food, which is not connected to anything else?  Need help please, cannot afford to buy a new computer and it comes to the central computer of my house.  I know a lot of things apart and do their work, but these slimlines suck.  now I know why, they are thin because they have emptied the thing.  computer first for a school kid, but not someone who keeps her home running with everything I do.  So where to connect?  How can I get this thing to work, because it fits so well after all this time looking for the right hardware?  the only reason for which I installed today was because a disc is stuck in it, because the disc is made to be vertical, another error!  disks grind and get lost in there... but I would like a response to my concern at the moment... can not replace the thing and did not have my only other more... Thank you double checked okay there a power connector to the white thing with pins but to connect and what wire?

    To Associate Dean wb2001

    The firewire card is fine as I had mentioned previously.  I installed it and the computer knows it's there.  I really don't see why the name of the thing is so important.  I DON'T PLAN to buy anything else for the problem I have, and I never told him I would.  The only question was if the thing needed food and where to find it, but on mine, I found some answers to that too if I have to use this way.

    so I have thought my problem already and the card firewire is fine.

    That's just the problem with the software now.  I was going to change the thing to the other pci slot and see if anyone makes a difference, but the computer has recognized the new hardware.  This isn't something to do with the firewire card or computer.

    As your couriosity is so bad, Dean associated wb2001,

    I had bought the firewire from newegg like this card and found the profile down those who have the extra bracker for proper size.  It is manufactured by Rosewill.  went with no problem, really easy.  but these slimlines haven't ligned up very well the other slot PCI express.

    It may just be the old camcorder... What is needed right now is the driver for the thing.  an trv520 sony handycam dcr.  I don't know if there is a driver, but when you look at I found one, but still does not recognize the camcorder.  then, in windows, they said all the drivers are included in the operating system for these things, but do not automatically install it like any other.  I'll most likely find the answer by myself around the research on this topic, or I could receive a fair he made on discs, since I only have a few strips of film, but was hoping to get to again use this camcorder.  so I'll see.

    Then Associate Dean wb2001

    I don't even understand your statement!  mix you some point of what the devil, is a lottery?  MY BEHAVIOR WILL NEVER HAPPEN!  I'm still learning what I find, I just took part an out Alienware desktop computer while he was blue screening and crashing on my son, now it works like new!

    You didn't not give me a solution, I found it myself and an attitude you squirt!  I wouldn't be here to help other people with the same problems I am and if I found the answer, I would not share expected points and giving a few statements of nose snot... For the record I WAS NOT LEAPING TO BUY ANYTHING!

    I GIVE YOU THE THUMBS DOWN!   Associate Dean wb2001

    I'm not a stupid kid, I had worked with one of the first concepts of a desktop hp back in the early 80s shipped directly from California.  has shown the President of the company about what I could do with the software that has accompanied, that was enough to make them one of the first companies to use the registers of retail computer that we see now and abandon the old IBM.   Although these dinasaurs are always being used LOL.

    so I don't deserve your forest to a condescending attitude!

  • My iPad is constantly in charge, even if not connected to a power source. Also, it allows me to turn the unit off. No idea what is happening?

    My iPad has always been in charge since I unplugged it yesterday and I thought that it might help if I turn off the device. But it turns out that he will not turn me off. I think it is causing other problems that I am more able to launch applications. I'd appreciate any help.

    Well it cannot be supported if it is not connected to power. So there must be a problem any which prevents the loading message on. Try to reset your iPad. Press and hold the Home button and the sleep/wake button until the Apple logo appears. Then release the button and let the appliance restarts. You lose no data by doing this. It's like a restart of the computer.

  • WSN-9791 frequency selection and interference

    WSN-9791 indicates that it can operate on the 2.4 GHz band channels 11-24 (I'm guessing that USA is limited to 11).  How to avoid multiple interference OR WSN, in the same neighborhood?  Is there a way to set or determine the channels that the network is working in?  For example, with the 802.11 standard common internet hubs can fix them to use one of these 11 channels.

    Thank you

    Garrett

    Hey Garret.

    You are right that channels 25 and 26 are outside the range of 802.11, but they cannot be used for the same reason that you can't go to channel 11 for 802.11 here in the United States.

    Also, for the gateways in the same neighborhood, you must assign different channels.  Gateways running on the same channel in the same vicinity will cause problems for both networks.

    The questions keep coming!
