Thanks. I'm building my two psu's into a case with my charger and plan on wiring them together to one outlet on the side of the case. I was just curious on how others had done it.

A $6 plug strip works great. And you can plug in your heater too

sub

Does anybody have a method of wiring the PSU to provide constant voltage regardless of current output?

I've tried:

Running ribbon wire 8 (-S) to ground through a resistor
Running ribbon wire 8 (-S) to ribbon wire 6(+S) through a resistor

In both cases, the voltage increases with current. I am trying to achieve the highest voltage output to avoid encountering the boost-buck problem when charging 3S (or 6S in a 24V system).

When I test mine (without adjusting voltage) they stay at virtually the same voltage for all loads. The only drop I get is in the external wiring.

Does anyone have a sense of how much longer the DPS-600PB will be available on eBay in bulk quantities? Is it reaching the end...if so, is there another server power supply that will replace it with a similar low price and great value?

The DPS -800 looks pretty good to me.

I have some and they work fine but not used them yet.

800 Watt and fully automatic fan speed control. Not too noisy even flat out.

Would be my current favorite for a 24V 1600 Watt supply.

See here for connections.

Yeah, I was looking at that one earlier...looks like it might be the next "hot" one. I hope the price comes down some on eBay though, it's still kind of high (compared to the good old dps-600pb at least).

What is the best way/or connectors to use to install banana plugs to the rack mount connectors of the PS. I have made 3 of these PS's and that was always the weak spot for me.

The IBM x3650 power supply (12.1v 69A) looks like a promising replacement.

I use 4mm bullets and just wedge them between the rack mount connectors, not the small opening, that would be impossible, but between the two sets where there is a larger opening. I use plenty of solder and make sure it gets hot enough. I have a really nice temperature controlled soldering station which helps a lot! It takes practice but you can get it with time. I also make sure I get solder on all points that come in contact.

I put two bullets on each lead and put them slightly in a V shape so that you can plug in two chargers next to each other (if you butt the bullets up next to each other with no separation there is not enough space to plug a second charger in). I actually made a little jig that I use to make sure the V shape is the same each time. I'll attach a picture showing the jig...the one on the left has the bullets on it ready to solder onto the PSU. If you end up making a jig like mine, a word of caution, be careful not to leave the iron on too hot as to wet the solder holding the jig together and then your jig falls apart. And two, don't solder the male bullets into the females...I've done both . The 4mm female bullets have a little hole in them (not sure why???). I just make sure that little hole is facing out and then don't get any solder near it and I'm usually fine .

Oh, and I want to add...the way I made the jig was first I carefully got two females soldered onto the PSU without a jig just the way I want them. Then I plugged in two males, put a 5mm female across the top of them and held it in place with a helping hand (I think that's what it's called...that little thing you get from Radio Shack, eBay...that has the aligator clips to hold things in place while you solder) and soldered them in place that way being careful not to get any solder on the males where they are plugged into the female 4mm bullets. Then pull the males out and you have your jig.

Thanks kingiggy262, I'll check that one out.

I have a problem with my hookup on my power supplys in 24V configuration as per Tjins site.

I shorted pins 6,9,10 on both units

hooked up units in series:
positive on #1 to negative on #2
positive output on #1 and a negative output on #2

I am only getting 12 VDC out of the series output connection?

I used my voltmeter and #1 power supply measuring voltage between the positive and negative poles I get 12 VDC, but measuring between the poles on #2 power supply reads 0 VDC.

Thanks for the help.

Did you float the DC on the higher unit?
