The kits gives you a bunch of features that makes it awesome – precision laser trimmed regulators for constant current to the laser, 0.01 tuning resolution, digital isolation, soft start, esd protection, current limiting, and the list goes on. It was also manufactured with safety in mind! The US Federal Government has a list of things that are required for operating these high power class 4 lasers. They might seem trivial, but they could save your eyesight! Here is a run down of the new safety features to protect yourself and others:

Key Switch – This key is needed to enable the laser. When the key switch is turned on, the laser is enabled and the key CANNOT come out. You can only remove the key when it is disabled. This feature is good if you have curious children have your laser in a shared area and want to limit use. Just take the key out and hide it!

Remote Interlocks – This feature allows for addition of switches to your enclosure so when it is open, the laser will automatically turn off. Also provides for the addition of an E Stop button for the laser, which is always good for if you need to stop the laser super quick! Add as many switches as you want to make a super safe area for your laser machine so nobody can accidentally look into the laser.

Power Fault Protection - This one may seem like it is not needed, but hear us out. Consider your power goes out in your area where the laser is located. You were running your program and then everything is dark… Power doesn’t come back on for awhile… long enough for you to forget that the laser was left ON! You come back and are checking your laser and boom, the power is back on, right when you are looking straight at it. Well, don’t worry because the laser will be disabled whenever the power to the driver is lost. Press the reset button and you are back in action!

Emission Indicator - The small little LED on the front to let you know your really super bright laser is on… They require this in case you are using an infrared invisible laser.
