Question Directly Power LD with PSU

I read quite a lot of info here at LPF on this subject and I think I understand what specs I would be needing to do so. Does anyone know anything about this: ATTEN Variable DC Power Supply APS3005S 30V 5A Lab | eBay???

If it's 5 Amps and under $200 I would consider it I guess...

Please bring on the opinions, I value each and every one of them =)

Thanks

Josh

No Idea about that supply but the price range is similar to the Chinese ones. I know Blord uses on of these Chinese units to directly drive diodes.

These units may be prone to spikes so you might want to add a capacitor on the output when testing laser diodes. Make sure you short out the output before connecting a diode.

Great point. I wonder how bad this thing oscillates??? Maybe I'll just buy a scope too and test it out myself...

I have a mastech HY1803D and love it. Got mine for $40 from a member. Can't imagine it's too much more new.
It's the same one DTR and many other members use.

Joshua;

I have previously used a very similar Mastech supply.

It does have spikes when turned on and off.

If you ramp up voltage . . .

and ramp down voltage it is OK.

I did lose some Red laser diodes with it.

Here is a good company to buy an inexpensive (~$50) lab supply from:

Benchtop Power Supply, Variable Bench Power Supplies | MPJA.COM

I have moved up to a more stable Extech switching supply,



The 4 Digit readout allows plotting diodes with better precision.

Thanks Larry,

I'm definitely going to buy a cheap one first, and save my money for this beast =) Model 1761, 1760A Triple Output DC Power Supply Series - B&K Precision
