zener diode


Which one? Akschu? I've been to the digikey site and there are many different mw and other specs on these. Which one would be a good choice? I like the idea of this safety, but I don't know enough about this stuff to know which one would work well. I wish someone would go into better detail on where to install the diode. And please, I'm not an electrical engineer, but I'm not an idiot either. I'm putting two supplies together for a flying buddy and I want to make it as safe as possible. I've already converted 12 of these dps-600pb units for other guys in my flying club. All have been converted internally. This is my first attempt at using them in series. I appreciate all the information and have much respect for those of you that have contributed so far. Thanks - Tim

Varying the voltage on pin 4 from 5 to 12V changes the speed, but it also is load dependent and will speed up automatically if necessary I believe. (haven't yet tried it).

Also this whole thread is useful on these PS.

The DPS-600PB power supply has two places to connect to DC ground and another two places to connect to the +12Vdc outlet. Is it important to use both pairs of the ground and positive connectors? I was thinking of putting female spade connectors to only one set of each outlets.

No need to use both as long as you solder to them. I'll connect a set of outputs to each one so I can run multiple chargers. In my blog I have a how-to showing the way I solder 10ga leads to them.

Ive seen a few people wrapping there power supplies in what looks like a heat shrink tubing or some type of shrink wrap...

You can get shrink wrap at Graingers, Home Depot or Lowes, Ace Hardware etc. It is clear and is used for wrapping various products onto wooden pallets to keep them from shifting and falling off during transit. I like the 5" wide version myself. It is not adhesive, you just stretch it, and it attachs to itself. It's good stuff.

I bought two 1 foot long power cords on EBay and plugged them into a power strip that has an off/on switch. It's handy.

Use google and search for a place in Bellevue, WA selling computer case fans-in the meantime, I'll try to find it.

Here's one: http://www.coolerguys.com/
