I reckon you will have an issue supplying it with the needed current... LOL

•Operating Current: around 100~110A

 

[bhwollen]

well it seems im the highest bidder... Not quite sure how I will use it though... assuming I get it, which I doubt.

 

[bhwollen]

well I actually won...

Now to power this thing...

:drool:

I don't know But i Want Review!

Or sell it!

I bet it'll cutchoo good if you stick your hand up ons.
You will probably have to wire it right into the supply lines for your house to get over 100 amps

 

[LaZeRz]

Well, your probably gonna have to buy a thousand dollar or up PSU...

BH:

If it was me, I'd parallel 20x 1084 based linear drivers, with balancing resistors. Then I'd feed it from some kind of 500W computer PSU.

But that's just my odd style.

I think you would still need something like a linear driver (array?) in between, otherwise the PSU might try to regulate the voltage at 5V, which would be too high for the diode bar?

If its the 100w 808nm from sinolaser then it's a QCW diode bar! and needs a maximum of a 20% duty cycle, it's typical "on" time is 300us

Only $37 after a few bids. Even if it's $200 dollars by the time it ends that's only $4 per diode.

I'm pretty sure they're fine at 60W CW.

I'm pretty sure they're fine at 60W CW.

i've also recently bought one of these 100watts, in the process of putting together the QCW driver. If you are right, then it sure would make things easier. The pulse timing is the easy part, its the pulse amplifier that has been causing complications, but I may have it right with my last attemp (been trying to get a clean square waveform after the huge amplification).
Also dont just want to apply CW, in case I bust the diode!

 

[bhwollen]

Would that actually work? lol

Buy seriously, I remember somewhere on here seeing someone talk about using a mosfet as a current sink. Don't remember how exactly but I'm sure it wouldn't be very hard to find. You should be able to find some mosfets able to handle that current, maybe parallel a couple.
