This is a used argon laser power supply that was removed from a facility that was closed-down. It is in very good condition and it has been tested and is fully operational.  The serial number may be different from the one in the photo.

The key is included. 

It is a JDS Uniphase model number 2114 - 020GLCKDK 

The input voltage range is: AC 200 - 220/230/240 Volts

It is possible to set this power supply for lower line voltages such as 100-120Vac by moving the internal jumpers.

It can be operated using a remote control interface or by jumpering some of the contacts on the DB-25 user interface. 

I will send the pinouts so it is easy for you to do. I have worked with these power supplies before so I am familiar with them.

This power supply should operate the following lasers: JDS Uniphase model 2211, 2212, 2214, 2218, and 2219.  The Spectra

Physics model 163D, and 183D and the Lasos model LGK 7877 and LGK 7880.  Almost any air-cooled argon laser that has the same connector on it, except the high power model 2213. I can include the pinouts for the laser head connection in case you are inclined to hook it to a laser other than those listed.
