How to control HV power supply (0-5V control voltage)?

Hey there,
I (LV newbie) wonder how to control my DELTA ELEKTRONIKA Powersupply with Labview. The control interface is a 0-5V analog input to set the power supply's output current.
Also I want to get some feedback of the set power supply current from an second (GPIB-controlled) instrument.
So how do I have to program a closed loop contol (application is not time critical), cause it would be mixed up of controlling by analog out (0-5V) and feedback loop driven on the GPIB-Card?
For a first step a simple control loop to set the current and monitor it on an analog input would also be an assistance .
THX for anyone helping

Look in the example finder for DAQmx functions for analog input and analog output.

To Control a Power Supply via LabVIEW

Hi,
I am really in the beginning of the learning LabvIEW. I am trying to control a power supply( Ametek XG
1500 ) via LabVIEW through USB cable. I have goggled several websites, but still do not have a clear idea
of how to implement such task. I downloaded COM drivers from www.programmablepower.com. Then, device and
my computer see the USB cable, but I do not have exact clue to make a good program to control power
supply.
I tried to make a program with NI-VISA with SCPI commands. Actually, I am not sure to write true
commands and I can not see the voltage or current value on the front panel. I have never write a program
to control any electronic device. Maybe, I can not see the basic step or not.
Firstly, I want to write a program which makes power on/off to the power supply. I do not know where
should I begin. Please any of you give me an offer to do this task.
Thank you.
Deniz

There is of course, the IVI driver.
I don't understand at all why you would install a different com port driver than the one that comes from Ametek/Sorenesen. In any case, I did not use the IVI driver. I simply created my own using Tools>Instrumentation>Create Instrument Driver Project. Pretty simple for me - I did a basic driver in less than a day. I would suggest you look over the instrument driver tutorial (on main idnet page). The commands are well documented in the manual. Be sure to get the termination characters correct. I can't provide the code I wrote as it was for a customer but if you post what you have written with details on errors you get etc, I'll try to help.

GPIB-Controlled XHR Power Supply and HP34401A DMM Conflict

Dear Experts,
I downloaded a driver for XHR Power Supply from NI's website and used
it to controlled the power supply successfully via GPIB cable in
LabVIEW. However, when I used HP34401A digital meter to measure the
voltage from the power supply in the same way via GPIB cable, the XHR
power supply was shut down automatically although the meter read the
measurement correctly before shutting down. Since I am a new user of
LabVIEW, I do not know if it is a conflict of GPIB-Controlled
instuments.
I would be most grateful if you could give me some advice and tell me how to solve this problem at your earliest convenience.
Thanks a lot for your attention and help,
James

You can set LLO with the VISA GPIB Control REN function. This is on the Instrument I/O>VISA>VISA Advanced>Interface specific palette.
You do not use the same VISA session for two different instruments. Each must be different and unique. If they were the same, then the be would be using the same address and your program would not work.
To make a sinlg VI that will control both instruments, just take the functions you need from each and put them into a single VI. The author of the XAN power supply drivers did a kind of lame thing. The Getting Started VIs do not have their controls and indicators wired to the VIs connector pane so you would have to change this before using the Getting Started in another VI. I've attached a simple example that shows some of the other functions along with some 34401 functions in a single VI.
Before you get going, I would recomend that you take a LabVIEW programming class. Information can bge found at http://www.ni.com/devzone/lvzone/fundamentals.htm.
p.s. You should know that your email address is not available to forum users. If you wish an example program, you can request it be posted here but you need to provide the version of LabVIEW that you're using and you need to provide the exact name of the XAN driver you're using. I found three and don't know shich is which.

Why does my FP-1600 take a 24V .5 Amp Power Supply and drop the Voltage to 11V at .5 Amps?

I have a FP-1600 connected to 4 FP-TB-1 bases. 2 FP-AI-100, 1 FP-TC-120, and 1 FP-AO-210 modules. I am powering the FP-1600 with a 24 V .5 A power supply. There are no devices currently connected to any of the modules. The power supply should be supplying 12 W, which should be enough to power the FP-1600 and the 4 modules according to the power requirement calculation in the manual P = 7 W + 1.15*#modules. When I install the third module, the FP-1600 stops communicating. Checking the power supply I see that the voltage drop across the power terminals on the FP-1600 is only 11V and then measuring the current being drawn it is .5 Amps, which is only 5.5 W, not enough to power the devices. When I unhook the power supply and measure the Voltage it is 24 V.
Why is the FP-1600 dropping the Voltage to 11V? Should I just purchase a 12V 2 Amp power supply?
Thanks for any help
Jeremy

Hello jqk,
You got it figured out. The maximum current that can be drawn is .5 which is too small. As the current being drawn approaches the maximum allowable current, the voltage will begin to drop. Eventhough the current you measure is .5A, the fact that the voltage is 11V means that the circuit requires more current to function properly.
As a rule of thumb, you want the maximum current your power supply can deliver to be at least the double of the system's maximum current consumption.

Help Using Labview to control Kikusui power supply with a PIA4850 controller

HI I need some help using Labview to control 4 Kikusui power supplies. We have a PIA4850 Kikusui power supply controller. I can use the visa test panel and see the PIA4850 but can see any of the power supplies. I have very limited use of Labview and only wrote a couple programs using GPIB. The PIA4850 is a USB controller and can control up to 32 PS. I can get it to work with a Excel demo software that came with the controllers so I know that it is working. Any help will be appreciated. I am using LabView 8.2 and have updated to the Ni-DAQ 9.0. I have a program that I need to incorporate the PIA4850 into once I figure out how to operate it. Thanks in advance.

HI and thanks for the help. I did get one power supply to work but have another problem. I need to control 4 power supplies at the same time and can only operate the one that is addressed N5!C1. If I set the other to N6!C1 and so on I get an error stating
“Error -1074135008 occurred at ki4800_2 Configure Voltage Level.vi Possible reason(s):IVI Error in the method "get_Item" in the component "Kikusui4800". E_IVI_UNKNOWN_CHANNEL_NAME: Unknown channel name (N6!C1)”
I am assuming that I should be able to change the node number and that will change the supply that I need to use. Everything works great if I use N5!C1 I can change any of the supplies to address 5 and can control it with no problem. I can even have multiple supplies with the same address N5!C1 (don’t think I should do that) and change them all at once. I need independent control of each supply.
I am in a pinch here and need to figure it out but could use some help. Any ideas will be greatly appreciated.
Thanks

Lambda power supply+labview+current control

Hi there,
I want to control the output current from TDK lambda power supply based on input from a pressure sensor. Based on available drivers from Lambda site, I was only able to output certain current and voltage value. But don't know how to control it depending on other input like pressure reading.
Is there any way to do this in labview?
Thanks in advance.
Arihant.

Unfortunately I don't have drivers for either of 'Pfeiffer vacuum gauge controller' and 'TDK lambda power supply'...!!
But went through your code, and it looks like you're reading from both the instruments... but you should be reading only from 'Pfeiffer vacuum gauge controller' and should be writing (current or voltage or both values) to 'TDK lambda power supply'...!!
Now before you write the new (current or voltage or both) value(s)... you can place a simple algorithm that will calculate new value (based on reading from 'Pfeiffer vacuum gauge controller')....!!
I am not allergic to Kudos, in fact I love Kudos.

Spellman power supply SL40PN2000 remote control using Labview

We have a SL40PN2000 Spellman power supply. We want to do remote programming using Labview program.
We want to control the voltage output.
Many thanks for your help.

You need to first determine the remote control interface. Is it GPIB, RS-232, Ethernet, USB, etc.? In the case of GPIB, you would need to purchase a GPIB controller.
There is not an existing instrument driver but you can review the information here on what a driver is and how to devleop one.

Labview 6.0 run-time engine will not control BKPrecision power supply.

I created a test program in Labview 6.0 to control a BKPrecision power supply and Measurement computing DAQ in our test system. I am able to control both intsruments from my PC which has Labview loaded on it. I created an executable from the application builder tool for distribution. When i install the run-time engine and executable on a new PC (Labview not installed), i am unable to control the BKPrecision power supply. The BK power supply is connected to the serial COM port of the PC.
Do i need to install drivers that are not included in the executable build?
Do i need to install VXIpnp (VISA interactive control)?
thanks,
Tim
Solved!

tmann-
The API Drivers are often times for more specific Operating Systems than the others (Linux, Pharlap, etc.) and they are more easily accessible for programmers that want to (and have enough time to put up with the headaches ) of building speciality drivers off of ours. 99% of the time you just want the drivers that come up first when you type in your driver name (NI-VISA). As to versions, issues can crop up later from not using the exact same driver version but all the drivers are built off of each other (they hardly ever scrap an entire driver and start over) so the problems should be minor. Its up to you about switching. Unfortunately to downgrade version you have to completely uninstall the driver from Add/Remove Programs>>National Instruments Software>>Your driver and then reinstall the correct one. If you have time, I think it is well worth it to do it right the first time. Hope this is helpful!!

How to change the power supply to the CD/DVD Drive so that it is off by default?

When running on battery I often use the "Safely Remove Hardware" icon from XP to "unplug" the Mat****a CD/DVD drive in order to safe some battery life.(Does it?) I use Fn+Tab to bring it back to life. I wonder if there is a way to make my Notebook (M400) boot with the power supply to the Drive off by default. By the way, any idea where I can find the extra battery for the CD/DVD-Drive slot and at which price?
Thanks in advance for your help.

Hello Robert
If you check start page you will see that this support forum is not any kind of Toshiba support directly but user-to-user forum. But you are not alone and many users expect that some Toshiba support team sit in the office and wait to write answers.
Anyway there are many Toshiba notebook users with very good knowledge and also enthusiasts who try to help other guys with different issues and also share own experience.
Professionalism is not forum but action when you need assistance because of hardware damage or something similar. If you need competent answers and help every authorized service partner should be able to give you info you need. But please dont mix service partner and Toshiba because it is not the same.
Anyway I have found info that you can use additional (second expansion battery) and it should be batteries with part numbers PA3510U-1BAL and PA3510U-1BRL. I can not tell you how much it costs but you can find it alone using Google.
Back to your first question: If I am understand you right you want to save more power and because of that you want to disconnect ODD. It is nice idea but you have obviously misunderstood something. "Safely Remove Hardware option is there to help operating system and say this hardware part will be removed and dont exist anymore but it does not mean physically disconnection from other hardware.
If you need more power use second battery and enjoy your life.
If you have more questions you are welcome. Many users here have M400 and I hope in the future some of them will participate a little bit more.
Have a nice day! :)

How to recognize fake power supply for iPhone?

Hello,
last year in August I purchased at Amazon a "original" power supply plus USB-Cable for my iPhone 3GS. Now this thing sometimes works and sometimes it doesn´t. I called the vendor but he sees no responsibility for the artivle because it is out of warranty.
I told him that to me (and by comparing with other Apple-Hardware) the article looks pretty fake and therefore it does not matter if it is out of warranty or not - he sold fake hardware with "original" labeling on it.
Now I would like to verify my guess and see if this thing is fake or not. Do you have any idea how I can do this or what I should do now?
Thank you
kcn

To some extent it depends where the OP lives. In the UK and the EU warranties are expected to be for two years (though Apple still advertises one year). There are however, different definitions about what a manufacturing fault is.

How to check the power supply? iMac G3 233

How to do it?
Can i just take the case with the mainboard out and "short" the pins Power on (pin 8) with GND and check the voltages on the connector that comes out of the monitor case?
I know that the pin 8 is the power from articles about imac>atx case conversion.And i know that you can power up a normal ATX power supply by shortening two pins, and want to know if i can do the same with iMAc power supply. I don't want to fry anything.

Sounds like you have eliminated most of the possibilities, other than power supply board or motherboard. But it may also be the CPU daughter card that is faulty. I had one (233 MHz) that would run Mac OS 9 just fine, but it was unable to run Mac OS X reliably (crashes and freezes after a few minutes). I replaced it first with a 333 MHz G3 card off of eBay and later with a 467 MHz G4 card from the Fastmac booth at MacWorld San Francisco two years ago.
If you are comfortable disassembling the iMac to the point of removing the power supply board, you can layout the PS board and the carrier assembly (the thing you pull out with the motherboard, CPU card, and drives) on a table top. Then connect the power supply board to the carrier assembly, and connect the external power cord plug to the power supply board, and connect a keyboard with a power button to the carrier.
To measure the voltages, you can disconnect the 4-pin connector to the hard drive. If you turn it on using the power button on the keyboard, it will not start up with the hard drive not powered up (unless you use a bootable CD), but the system should be powered so that you can take your measurements.
Hope that works. Be careful with the exposed back end of the CRT. Keep any curious cats out of the room while you do this...

Finding Address of Ethernet Controlled (VXI) Power Supply

I have a PXI system, and a TTI CPX400 power supply connected via Ethernet. In order to initialize and control these power supplies with the premade VIs, I need to supply a resource name in the form of: TCPIP0::<IP>::9221:OCKET. The concern I have is that each power supply has a different IP address, and in order to determine it, I need to connect the supply to a computer and run an LXI Discovery tool (http://tti-test.com/go/psx/psx-downloads/lxi-discovery_tool.zip), which is a windows, GUI based tool. I would like to know if anyone has a solution for identifying such a device and finding its address in some way that can be implemented from within a labview program, so that if a power supply is replaced, communication can be established without having to manually run the discovery tool and then enter that address into my configuration file. Also, the power supplies have unique host names, so I can't just look up the address that way.
Thanks for any suggestions.

By far the easiest is to just set a static IP address for each of your supplies. It is just let setting up a GPIB address. Most supplies have menus on the front panel so that you can set them to have a static address. I do this for all of my LAN instruments.
There are only two ways to tell somebody thanks: Kudos and Marked Solutions
