The Cohesion3D Power Supply



The Cohesion3D Power Supply: all about it and why your board needs it.

The Cohesion3D LaserBoard comes with a power supply included, and for the Cohesion3D Mini Laser Upgrade it was and continues to be a strongly recommended upgrade item.

The Laser Power Supply (LPSU) that you’ll find in a typical laser will look something like this:

While it is capable of producing thousands of volts to fire your laser tube, it has a very weak 24v rail - barely capable of powering the stock board and stepper motors. It is no surprise that when you hook up a more powerful board, one that can run the stepper motors at higher currents in addition to a Z Table, Rotary Attachment, and other peripherals, this simply cannot keep up.

Here is our Cohesion3D Power Supply. It comes with all the LaserBoards and plugs directly into the DC Jack on them. It is also available for Cohesion3D Mini and comes with the necessary wiring and adapter to connect to that board. With this you are taking the load completely off the LPSU and powering the Cohesion3D Board with 24v entirely from the new supply. On the Cohesion3D Mini you would snip the 24v wire going from the LPSU to the board, and on Cohesion3D LaserBoard the 24v from the LPSU is pre-disconnected out of the box - LaserBoard must have power from the separate power supply to function. However, you must still connect the typical laser power plug to the laserboard, as it contains the LaserFire and Ground reference lines to control the laser.

To be absolutely clear, the C3D Power Supply does not replace the Laser Power Supply. You still need the LPSU to drive the laser tube, and the C3D PSU will drive the C3D board.

The power supply is capable of 110 - 240v input, so that’s not a problem for international customers located outside the USA. The cable that goes to the wall outlet has the USA prongs on it, so international customers need either need a simple adapter piece to go from the prongs to the USA prongs,or you can get the “outlet side” power cord for your country.
In technical terms, the power supply has a male 2-pin C7 connector, and you need a cable that will go from that to your electrical socket for your country.
