Hello everyone! I am reaching out here hoping for some help. We are a small laser etching company based in New England in the United States. We have 3 laser etching machines; Allen Datagraph 14400, Allen Datagraph 6000 and a custom build Cochrans Laser Etching System. All these lasers are engraving portraits and images onto granite headstones and granite plaques.
The Cochrans Laser has a power supply unit from Power-One D.C. Power Supplies Model #SPM3E2kS442. This Cochrans Laser Machine was built in 1999 as well. It's not within our budget to purchase a new laser at this time so we're trying these alternative routes.
This power supply continues to fail to power the laser head and we are looking at getting the PSU rebuilt for a second time.
We've browsed most of the online marketplaces out there and haven't found anything. Is anyone know of a company or individual where we can find additional units in this model or an economical rebuild for the unit.
I'm going to assume because this company no longer makes these that it's nearly impossible to find a new one of these out there.

Thank you for the help!
Regards,
Colin.A
