My problem was not with normal operation, normal operation is excellent.
My problem was after making a tiny adjustment to the very sensitive pot.
After adjusting it there was a wide variation in output until it went through a couple heating and cooling cycles.
Reply to Lifetime, NICE, looks like you got a freak of a diode there, on page 1 it looked like 5 watts was it, after that it was all spectral shift but no more output. Good looking build, sturdy, I'm a big fan of battle ship sturdy.
Iam surprised you find these pots that sensitive on the top end. There pretty good ~+/-50mA on the very very top end 4.8A+. But if your comparing it to a multi turn pot then yeah these are sensitive.:angel:
To make them even less then what they are now it will keep brining the low range current up more and its already at ~900mA. I would have to put in a 3rd range to counter that which there is No room.
Or it will increase cost if i get a Nice Multi-turn pot as well as make the driver profile taller.
This is the best fit pot i found that gives best full range without loosing the bottom end.. Trust me if i could have made it better i would.
If any of you guys want a custom request for a multi-turn pot Just PM me and ill make it for you. Iam Only a Pm away.:beer: Just let me know Or you can ask DTR or Flaminpyro for the request and they can make it happen.
Maybe ill make a separate option that is specifically designed for more of the top end "Like 3A+ or 4A+" for you guys that want a little more control on the top end Only and dont care about loosing the low end of the current range and uses this other single turn pot i have that should give you easier adjusting and not effect cost or use a Nice Bourns Multi turn pot for those that would like to have even more fine control that wont care about the extra pot height.. Though this will be on request because most need as much of the full current range as possible.
So send me a PM if you would Like that. Id be more then happy to make you a custom request.
Yeah Rich did get a Nice Freak diode.
Thats a Massive sink to so iam sure it keeps the diode cool at around 20-25C for some nice decent runs.
Remember the MAX Current/Max Power with these 07E/44 type diodes really depend on the temp. The lower the temp "even 5C difference" the more power and more current you can give it before the roll back starts. In other words The roll back might start at 5.2A at 37C but at 25C the roll back changes to ~5.6A lets say. Its different from diode to diode but depending on the temp from 20C-40C the roll back goes from 5.8A MAX down to ~5.1A...
