Power supply voltage upper-non-recoverable

Hello,
One of our customers is seeing the following errors occur intermittently across all 4 power supplies in their chassis. They are running 2.0(2q). The chassis is powered via an APC UPS and PDUs, and there are no power events or alarms from within the APC InfraStruxure tools. Has anyone else seen these errors in 2.0(2q) or is this error indicating a voltage fluctuation from the UPS?

Power supply voltage for using PoE splitters

Dear Community
What is the power supply voltage for Apple TV 3?
Power consumption has been specified on the Apple product site, but not the power supply voltage.
Should be 5, 9 or 12 Volt.
Thanks!

Help : power supply- voltage regulator

Thank you for all those that have replied me towards this power supply. In particular Lacy and Kittmaster.
I have developed a basic voltage regulator . However, I want to get a power supply that can deliver like 60V, and take about 10A current, because that what the load will require.
The regulator I have developed only delivers about 20V, I use the formula Vo = (R2/R3 + 1) * Vref. where my Vref is now 10V ( 2 zener diode). Even when I tried to decrease the resistance of R3, it does not make a difference.
Any help will be appreciated.

Power Supply Voltage Regulator.ms9 ‏1107 KB

O.K. I believe I have got it. There was a 2 fold problem with your regualtor and I will outline them below.
1) For some reason I could not get the 3-terminal Virtual Op Amps to work in this circuit. I traded that out for the 5 Terminal one. It is the very last one in the list of the Virtual category.
2) You are comparing your voltage from the bridge to your output voltage. If you have your input referenced to 10V and your output dviding this by a factor of 2 then once the voltage at the divider junction reaches 10V then the op amp will stop driving the transistor. Therefore you are only going to get 20V Out (ref*2 since both resitors are equal in value)). Therefore, you have to have your input reference to what you want the output to be. In this case 60V is what you want so you have 30V at the divider junction (Vo/2 since both resitors are equal value) your input reference would have to be 30V. I have never heard of a 30V Zener (they may exist, but it seems to me tha they would have to be quite large). so you may have to use a voltage divider on the input side instead.
It is my opinion that the design of this regulator is not going to work for you in reality if you decide to build it. The 2N2904 I I know is not going to handle 10A in reality. Based upon my findings I don't even know if you are going to be able to use an op-amp as the error amp due to the amount of voltage that has to be tied into it.You may be able to find such an op-amp but you will have to do some research to find one. I think most of the op amps in Multisim are low voltage in the range of 5VDC-22VDC. I would suggest looking on the internet and see if I could find a better alternative that uses more robust components or if you definitely want to design this on your own, reasearching the components in Multisim to see if any of them can handle the voltage and current requirements.
I hope this helps and I haven't confused you in any way

Plotting IVI Power Supply voltage

I am usint SignalEpxress to control to my Agilent N6700B power supply, and I am successfully commanding the instrument and querying the output voltage.
However, I can't seem to figure out how to plot the output voltage on a strip chart. The 'IVI Power Supply' step only seems to offer two output options:
'over-voltage tripped'
'over-current tripped'
It doesn't therefore seem possible to hook the output voltage of the step to a data view strip chart. Any ideas on how to accomplish this?
Thanks,
Aaron

@astibich, just out of curiosity, can’t you accomplish the same in software. Since you’re getting the required values of voltage, you can plot that within the PC. If required these values could then be transmitted to a real-time plotter as well. If you’ve already found a better solution to this, I’d love to know, just for information. It’s the ingenious ideas of people that actually inspire me, like everyone else, to think outside the box.

Airport Extreme Power Supply Voltage?

We just moved and apparently packed our AEBS separately from the power supply. Does anyone know the voltage and output current (or power) from the power supply so that I might use an alternative until we find the original?
I hate to spend the $20 (and shipping) for a unit I'll find some days from now...
Thanks,

The Airport Extreme power supply brick output is rated at 5.1V DC, 2.4 A. The polarity of the plug's sleave is negative, the center terminal is positive.

External Power Supply: Voltage?

Dear iPodders,
What voltage is safe to put into the dock connector of an iPod classic?
The travel power pack only seems to deliver 5v to it, but I've got a cable to use for connection to an in-car stereo, and it has a power feed that connects directly to the +12v of the car's battery!
Is this OK? Or is this dangerous?
- Dave

On the iPod there are two ways to get power into it. On the dock connector there are power input pins for USB and power input pins for Firewire. USB is +5V while Firewire is often +12V but can be a lot higher. On the Firewire pins you can input over 30V. What I am not sure about is if you can input more than 5V on the USB power pins since USB is standardized at 5V but that doesn't mean the iPod can't accept more on those pins.
Anyway, the automobile connection is very likely wired up to deliver the +12V car battery voltage to the Firewire power pins of your iPod Classic and that is normal/acceptable.

Has my G4 sawtooth power supply died?

My Power Mac G4 AGP "Sawtooth" will not start. It was in sleep mode when we had a two-hour power outage yesterday. Now the startup button does not light, even when pressed, and the machine makes no response.
I’ve checked the power cord and outlet, and both are good. The monitor, which is plugged into the outlet on the back of the G4, is getting power. The battery checks as okay, and I’ve tried a PMU reset with no response.
After reading over the discussion boards, it sounds like the power supply, but would a power outage cause that to fail? (It was plugged into a fairly good Curtis surge suppressor, but in sleep mode).
Many thanks for any help.
Gene

Eugene,
Both your website and Tom Bryant’s response (above) point to a definitive power supply voltage test, but I’m a bit intimidated by the red-print warnings of death for non-techies.
Dangerous line power is only present inside the metal case of the PSU. All wires going to the motherboard connector are less than 30 Volts DC. There is more danger the computer could be damaged by careless handling than to you.
1. leave the connector in it's seat on the motherboard.
2. Make your own probes for the VM with small insulated devices that can clip to thin wires -Radio Shack (NOT alligator clips).
....Get some sturdy decoration pins that will be pushed inside the wire holes of the connector to which the clips will be hooked.
3. be careful to not drop any metal object on the motherboard.
4. Unpower the mac while changing position of the pins.
It's still your responsibility deciding to try yourself.

Power supply problems

I'm currently running a 300W non-branded crappy power supply, the voltages are shown below. The problem is, the fan has pretty much given up the ghost and is making an outrageously load noise, I tried replacing it, firstly with 2 different types of Antec 350W powersupplys, both of which had to be sent back, and cost me loads of money doing so, now I've tried a non-branded 500W powersupply, but all have had the same problem: - They appear to begin to power up the system, the fans start for a second, then they stop, as if the PSU doesn't have enough juice to run things. It runs the system when I unplug the external power on the graphics card, but it won't run the graphics card on its own.
I guess this suggests it is more likely a graphics card problem, but if any of you guys have any ideas I'd be greatful. I don't see why a higher Power PSU would power the system when a much lower one would.
The 500W power supply voltages are:
+5V - 40A
+12V - 17A
+3.3V - 28A

I'm not sure what a D-bracket is mate. I've sent an e-mail to ATI to see if they know of any issues with certain power supplys, in the mean time I solved the problem by taking the fan out of the 500W power supply and putting it in my old 300W one not an ideal solution to the problem but at least I don't have to put up with that horrible grinding noise anymore!
Cheers for the help mate.

Guide to remove power supply

Hi. I have a PowerMac G4 Sawtooth and it does nothing when you press the power button. I think it is the power supply that is the problem. I have a replacement power supply, but how do i get the old one out? Is there a guide somewhere? Or could someone make one that gives me the basics to get it out?

Before you remove the power supply, you should check for "Trickle Power". Without this 5 Volt supply, your Mac has no hope of starting, and with it, your Power supply is likely working.
With the Mac nominally off, but the AC power cord plugged into the wall socket, and the main 20-pin DC power connector still attached to the motherboard, measure the voltages by inserting a meter probe into the rear of each crimped wire connection. The black probe connects to any ground wire (typically black) on the same connector. More information and the pinout diagram in the article.

Power supply in MDD dual 867 shot?

I arrived home today to find that my Dual 867 G4 was powered down, though I had left it on when I left this afternoon. Not only that, but it won't turn on at all - the power button doesn't light up, there's no spinning of the disks, no chime, nothing. I've unplugged and re-plugged the power cord, switched out surge protectors, plugged it directly into the wall socket - no dice. One thing I did notice, though, is that when I plugged the power cord into the back of the G4 after I had disconnected it, I hear a very faint and periodic short noise, maybe every one second, from the back of the G4. Almost like a short buzzing noise, but too quiet and brief to really be called that.
Does this sound like the power supply is shot? Like it's shorted or burnt out in some way? Thankfully I have two iBooks to use in the meantime, but most of my daily used files and such are on the 4 hard drives in the G4, and there's no space for them (particularly my music) on either of these laptops.
If I do need a new powersupply, does anyone have recommendations for sources? It seems sellers on ebay want the sell them for over $100.
Thanks,
Anthony

Hi,
Yes, that does sound like a power supply issue. It could also be a bad CPU card, or even the motherboard. To isolate the problem, I'd take out the power supply and measure the voltages across the different pairs of wires in the plug that feeds the motherboard. If the voltages don't equal what they should, as per the G4 MDD service manual, then you're in the market for a new power supply. And yes, the ones on eBay will go for 100-150 or so. Make sure it's stated to come from a working system. Untested power supplies could be dead ones from a similar dead machines.
If the power supply voltages are OK, then to isolate whether or not the motherboard, or CPU card is bad will require a spare motherboard, or CPU card, to swap with yours.
Sources for new, or rebuilt, power supplies include WeLoveMacs , DVwarehouse, HarCoreMacs , among many others.
Here is a good set of pictures and step-by-step instructions on taking the MDD power supply apart.
In my case, I had a spare motherboard and power supply to test with. The machine, which I got cheap off of eBay because it didn't work, did not turn on at all. Swapping first the Power supply with a good one didn't bring it back to life. Turns out the CPU card and the power supply were both bad. Once both were replaced, the MDD machine has worked fine.
Good luck!

NX 5K Power Supply

Hi all,
I replaced a new PSU I received from Cisco to replace a failed PSU. I issued this command "sh env power" but the new PSU isn't listed and the parameters for the Power show "0". The LED indicator is showing green and I didn't reboot the sw.
I was wondering if anyone has info on why this symptom. I'd really appreciate the input.
Best, ~zK

Interesting question.
Very short answer:
CPU fan.
Longer answer:
1. I use smcFanControl to control the speeds of my 3 fans in my iMac (2.8 GHz)
2. My "standard" settings are:
CPU fan: 1600 rpm
Hard Drive fan: 1600
Optical Drive fan: 1100
and my "typical" power supply temp is 65° C.
3. I did an experiment and bumped each fan separately up to its maximum speed.
a. Optical Drive fan: from 1100 -> 4400
PS temp: from 65 to 64
b. HDD fan: from 1600 -> 5500
PS temp: from 65 to 68 !! Oops.
c. CPU fan: from 1600 -> 3300
PS temp: from 68 to 42. Yea! But, it is noisy.
4. I then dropped the CPU fan speed to 2000 rpm and the PS temp is now at 52. I can hear the fan, but barely.
I am glad that you asked this question as I have reset my standard to 1800 rpm for the CPU fan. It is quiet and I appear to have a 10° C drop with an increase of 200 rpm.
One thing is clear to me. Apple's default fan speed settings are too low. We should not have to buy smcFanControl to extend the life of our iMacs, the proper speeds should be built into the machine/firmware/software.

Power supply and ADC monitor.

Hi everyone!
I know my topic title is a little tricky but I am ready to explain what is going on.
My G4 1.25 MDD stopped working today.
I have spend whole day searching/reading to find out what is happening.
Result....I dont have a clue.
I have test the:
power supply voltage.OK
power switch. OK
Battery. OK
I have done all the usuall resetings.NO help.
I have try the keyboard from my old Gigabit ethernet that haw a power switch.Didn't work.
Then I thought to connect my old studio display...and......my mac woke up!Its alive....for now!
It starts up only with the display connected and from its power switch.some random times it starts from its own power switch but its very rare.
What it going on here?
Do I have a faulty PS or something else is happening?
Thank you very much and Happy new year!!

Hi Allan.
Yes the model is M2452 but it doesn't startup any of my two G4 MDDs.Maby its bad...I don't know.
The FPB isn't bad because I have place it to my other G4 and it is working fine.
I think that I should look at the cable from the FPB to the motherboard and the connecton on the MB.
It is very weird that the PS is working just fine without any problems so far(crossing fingers).
Its just that I have to power it onn from the studio Display.

How do I use LabVIEW to control and vary the voltage on my Agilent Power Supply and simultaneously record temp from 1 DMM and voltage from another DMM?

I am using an Agilent Power Supply to apply a voltage to a
thermistor to heat an Al chassis. I want to use LabVIEW to tell
the power supply to apply 5V for 10 minutes, then step to 7V for 10
minutes, etc. I am completely new to LabVIEW, so any help would be greatly appreciated!
In addition to that, I want to place a type J thermocouple onto the Al
surface and use a Keithley 2000 DMM to monitor the temperature (it has
a built in conversion from V to Temp for type J). I will also be
using another Kelthley 2000 DMM to record the output voltage of a new
uncalibrated thermocouple. I would like to collect the output
voltage for this uncalibrated thermocouple and the temperature reading
from the type J simultaneously. How should I go about doing this
in LabVIEW? I will be using version 6.1. The power supply
and DMMs will be connected to a PC using GPIB.
Again any suggestions would be greatly appreciated- I have no idea
where to begin on such a project. I have taught myself how to
make a basic VI- converting temp in oC to oF, but that is as far
as my knowledge goes.

What you want to do should be fairly straightward and a good way to learn labview.
First off, if you haven't already, I would download the drivers for the Keithley and Agilent instruments. I found the keithley drivers at the link below. You will need to find the labview drivers for the Agilent PS at their website. Drivers are the VI's you will use in your program to control the insturments.
http://sine.ni.com/apps/we/niid_web_display.download_page?p_id_guid=E3B19B3E90B0659CE034080020E74861
If you open Labview and go to the help menu and click on Labview bookshelf there is alot of information on getting you started coding labview. This should get you started, if you have anymore questions just ask in this same thread and I am sure you will get all the help you need.
