Nice to see these new high power drivers added to your inventory, looking forward to seeing the specs! :yh:

 

[Garoq]

OK, the high power drivers are on the stores now and are available for immediate shipment:

U.S. customers: SL High-Power Adjustable Current Driver

International customers: SL High-Power Adjustable Current Driver

The basic specs are posted but more will be added soon.

Thx, Gary!! This looks really interesting

We have enabled PayPal for payment again on the international store at survivallaser.com. However, because of current PayPal policy, we cannot accept PayPal for orders that include a complete laser package. Orders that include a complete laser must use Stripe for payment. Any orders that include a complete laser and are paid with PayPal will be canceled and the payment refunded.

Sorry to hear this, but I find this so ironic. I'm betting you can buy all sort of ****ograghic stuff using PayPal and they wouldn't say squat. But they draw the line at lasers. Don't figure. :thinking:

 

[Garoq]

Yeah, between the FDA and PayPal it's been difficult to navigate this business.

Thank you, Bob and thanks always to the laser hobbyist community. I appreciate all the support we've received over the years. We just have to find new and better ways to work within or change the restrictions that still exist.

Hey Gary, I hope business is well,
I got my package from you yesterday, it’s amazing how much pride you take in the things you send. I opened it and everything looks so pristine and nice. It’s no wonder why I love buying stuff from SL.

Hi Richie, thank you for the kind words and it's always a pleasure to serve our customers like you! :beer:

I second Richie's compliment, it's always been a pleasure dealing with Gary and SL. :beer:
I should also be getting my small order from SL in the next day or two!

I was wondering at what current do these need to be heat sinked, and do you heat sink at the ICs? It looks like paralleled Buck drivers on one driver.

I would heat sink them at over 1.8A. Yes, heat sink the side with the two controllers.

I mount them to our heat sink driver pill like this:

This picture shows a prototype driver with two pots, but the one pot on the production driver is easily accessible in this configuration.

 

[paul1598419]

Thank you, that is good to know. I was about to ask about the two pots, but then saw you covered that. :thanks:
