Welcome to the forum! I have upgraded your trust level so that you can now upload photos.
This should be compatible, but we need to see your current wiring configuration to the board and LPSU connections to confirm which wiring option to suggest.
Please provide a picture of this as well. This sounds like a version of the high power power supplies covered in our LPSU Connection Guide. You can check your terminals in the article.
For the configuration changes to dial in the physics for your machine size, review our Larger Laser Machine Installation Guide.
You can read all about analog vs digital panel here: PWM Control. If you do not have one, it is recommended to install a milliamp meter to know what mA your tube is running at in relation to your digital control values, to dial in your settings and also prevent overdriving the tube. We have instructions for this, if needed.
These should connect per the K40 Installation Guide. Let us know if they differ from the instructions.
This will not connect to the LaserBoard, so you can continue to use the panel buttons to operate.
