Good Robust Power Supplies?

Hello, if there is already a topic coving this I apologize in advance!

I am looking to get 3 robust power supplies for my motion rig. I have had two different ones and the first set was mostly stable but wasn't able to run the Max Power % in Sim Tools higher than 98/99 depending on game. I switched to a higher wattage power supplies and now they are even worse and have to run them around 94%. (I'm not sure if maybe i just got a hard used batch and that is my issue). I am wanting to redesign my enclosure for all of my electronics and want to get this sorted out first so Im confident i have a metal enclosure big enough to hold everything.

This is the power supply that I had the first go:
Genuine HP Proliant DL380 575W Hot Plug Power Supply 321632-001

This is the power supplies that i am running at the moment:
Dell Poweredge 2950 750w Power Supply C901D JX399 X404H NY526 JU081

I am using JRK's with these motors:

Any help would be hugely appreciated and thank you again!

I was actually just re-reading this thread http://www.xsimulator.net/community...r-power-supply-for-12v.5774/page-2#post-85358 and was thinking that as well, I have the axis limiting around 40% i believe however may have gotten reset when i upgraded the OS, ill check that out tonight and post all of my JRK settings tonight

Im shocked to hear the 2950's are giving you issues Rundmg, I look forward to seeing all your setting's to see if there's anything we can spot.

Are there any particular cars/games you having issues with ?

not really a car or game specific just when motion is really working it (i.e. wreaks). but the thing is its not moving the motors far its just fast back and forth in a short distances since i have the axis turned so far down.

The reason I'm somewhat skeptical of the Dell's are one i got was DOA, will power on etc but as soon as your plug anything into it it trips (even a simple computer fan). And they were rather cheap, I got 6 for $45 (pretty sure that included shipping too). and more over the Voltage output is 11.74-11.80v. What is your voltage output on yours @Nick Moxley ? I know you have/had those and liked them a good bit

Post up screen shots of JRKS. But yes , LED power supplies have been flawless for me . I used them on my former hire sims. Never missed a beat.

Interesting, I still would like to see your settings,

My 600's actually run @ 12.5 and 12.6v I did notice the other day the Traction loss PSU was flickering between 12.6 and 12.7 My Amp gauges are for the most part Too quick for me to see the major spikes, So i honestly dont know what they are truly pulling for amperage.

the Ebay server units are cheap because they are technically surplus that guys are getting from Large Server farms who swap them out for New Units, The list price for a B.N 600pb is ridiculous like 5-600$. So again its unlikely they aren't up to the task. I would almost look into adding a small 7a 12v gel cell into the mix, Robbie and Dave have always harped to me about back current, and maybe that's part of it. 20$ gel cell test might be worth a shot. But again We have to see your setting's first to make sure there isn't something a miss.

Look to the graph on the right screeen, how much oscillation are you getting from off track moments ?

this is on the 600's

all right, so ive attached screenies from all tables of the config utility as well as the settings text file just incase there was something in there you guys wanted to see that i didn't happen to get

thanks again the help guys

edit: the power supplies were off at the time of the grabs so the no power error was legit

@rundmg
Raise Integral limit to 10000
Raise analog samples to 512
Raise max current to 0 (unlimited)
Apply settings

sweet thanks @bsft the max current actually was 0.00, i was playing with that before thinking it was pulling too many amps from PSU and forgot to change it back. I made the other adjustments as well and will give her a shot once I get a chance.

okay so quick update first holy shit did that make it feel soooo much better. was able to turn up the main level % to 97/98 and everything just was so much more alive. forgot how good it could feel (its been while since i really used this thing with work and all); however, it still trips at 98 at wreaks and anything above 98 will trip the psus but its mainly the one PSU so i think my underling issue there is the power supplies just are too beat down and used. plan on trying another set from another seller and hopefully the volts will be in the 12+ range. if not ill pony up the change for some 12v 40amp LED units and give them a go...forgot just how damn good this stuff feels. thanks again for the setting suggestions @bsft

side note: new rig build with 80/20 + 3dof coming soon - cant wait to share

Yes. Give profile fixes a try . Its difficult to keep total percentages at 100. But you found like the rest of us , drop main level down a bit. PID looks ok. I will have a look again when i get home

Also @rundmg , you're using motors at 66% (max duty cycle and max acceleration @400/600) so there's plenty of room to increase values.

Just for the record, Ive run LED power on my former hire sims. They ran for hours sometimes in 40 deg heat with direct sunlight on them.
I have NEVER had one shut down from current draw or heat.
I run LED supplies on all my sims, here and gone.
@Blame73 , running motor JRKS at 66% is fine, its amazing with a good PID and profile how nasty that can be. And they are not running flat out

What is the difference between max duty cycle and max acceleration? Acceleration seemed kinda self explanatory but how does that relate with duty cycle? Do we have any good resources showing how to play with the PID values?

Perfect I'll dig into those docs. Thanks for links.

Awesome suggestions guys, More than a couple thing's to try Rundmg. let us know how you make out. And for the record, If you have a 2nd screen or tripples. Run the JRK utility Graph with the Target, Scaled Feedback, Error, Duty cycle Target, And Duty cycle boxes checked. It will Help tremendously Understand when your motion is going into the "clipping" range and when you working stuff Hard. A Visual representation of the data is Really handy to see in Real Time.


Dave, remember tho the Hire units were NOT set up as harsh as some set theirs up to be (Understandable, Most noobies cant even drive with a Smidgen of motion let alone a Realistic profile)

Lmk how that VS3.5 works out on the Actuators.
