I see the time for me to get a nice Variable DC Power Supply has arrived.
With new laser diodes out there, my interest to build new portable and bench lasers has brought me back to this hobby. So, I am thinking on getting one, however, I do not which one.
There are a few thread here that recommend some of the ones available in eBay which are quite attractive and inexpensive (for less than $120), some with free shipment (to outrages $120 S&H) and warranties from 30 days to 1 year.
The standard specs of 30v and 5A max seems, at this time, reasonable since most of the current visible laser diodes are below that voltage and amperage (with around 3 amps for the new 445nm laser diodes). However, for high power infrared lasers, the 5A may be a limitation, as some will go up to 12A, so a 30v 20a may be useful, but they run in the $150-$250 price range. And... then there are the 40A and the 60A ones but I think is way to high for laser diodes (with price above $250).
As someone running and testing laser diodes, if you were to buy one, which one would you select and why?
Here is an eBay search link to those available for 30v 5a for less that $120:
30v 5a dc power supply | eBay
And here is an eBay search link to those available for 30v 20a for less that $250:
30v 20a dc power supply | eBay
Some of the ones I found interesting (in no particular order) are:
Precision Lab PS305 30V 5A HQ Variable DC Power Supply with 30 days guarantee.
X-TRONICTM 6000 SERIES - MODEL #6080 30V - 5A INDUSTRIAL/COMMERCIAL POWER SUPPLY with 1 year guarantee.
MASTECH HY3005D DC Power Supply Lab Grade Precision Adjustable 30V 5A Backlit
MASTECH VARIABLE DC POWER SUPPLY 30V 20A HY3020E 600W
Linear Regulated 30V, 20A DC Power Supplies TPR Series TPR3020
KXN-3020D High-power Switching DC Power Supply (30V, 20A)
Thanks!
