CnC Power Supply

Cnc power supply

This is a custom built power supply. The transformer that I put in my CnC. It offers 24 v and 12 v @ 31 amps on the 2ndary. It’s a custom built transformer that was originally used for high end stage intelligent lighting. On the primary side it offers U.S. and foreign input voltage. It offers, input and output fuse protection for both lines. It also has a mini fused power strip for a USB power splitter as well as any other wall plugable power needed . It has an internal fan and dual exhaust fans. In the front it has XLR inputs for mechanical end stop switches. Of course it also offers led’s as well as a spring loaded acrylic top that has solenoids to raise and lower the top. These are used for cooling. The fans also adjust speed and rotation direction according to cooling needs. The solenoids and fans are ran through an Arduino sketch that I wrote. All in all It’s a great power supply for cnc but it might be too bulky for RepRap usages.
