My 120 Amp mega test load :)

[GBD]

While everyone is enjoying pushing thier 445nm diodes to 2W, I desided to get in on the fun a little, and push a diode to 120As.. I figure if they are getting 2Ws or so from 1.8A of current, I could get around 132Ws out of a 445nm diode!

132W of 445nm.. That will be something else indeed.

Well, time to build a test load for it, For this i desided to use a few 120A 1200V Diode modules due to thier higher forward voltage, you may use 5 instead of the traditional 6 diodes, and I could not find a resistor, so instead I used a piece of welding cable, some copper plate, a can of lime pepsi, spotlight reflector, and a philips screw driver.

This test load works great, plug your driver in and your set!

Here is my setup:

That power will last less than a pico second I am fairly sure. :na: :beer:

 

[GBD]

Nooooo... with good TEC cooling, we can keep the diode from overheating, Im sure the aixiz module with a TEC will handle it.

Lime pepsi?! I'm sure cherry pepsi would yield more accurate results, but we're only talking a few thousandths of difference so it's not relative. Either way, that load is on a nice floor :beer:

I'll bet it will let out a scream in that pico second though :scared:

Im guessing he needed to find an interesting use for those 5
big honkin diodes...

Now to find a 18650 compatible driver for it :crackup:

 

[GBD]

Possibly correct, however the lime pepsi provides resistance slightly closer to one ohm on its coating, the cherry pepsi has yet been untested in a control lab enviroment.

as for the power source, we will use some china 18650s, the label says 200A/H. That must be a good source of juice.

its also been a known fact hardwood floors are far better at dissapating heat then copper heatsinks, however are still inferrior to TEC cooling.

Well at least you got some copper in there for cooling :crackup:
