Wiring, high voltage, and electricity can be dangerous. Read this first!

The voltages and electricity discussed here can be dangerous and could cause property loss or death. It is your responsibility to ensure you are comfortable doing the things discussed here. Furthermore your local jurisdiction may have regulations or rules which differ from what we discuss here, including wiring colors, standards, techniques, etc. Seek professional guidance from someone local to you if you are unsure of anything you're doing here.

FAST Pinball resells the Mean Well LRS-150-12 switching power supply which can supply the logic, lighting, and general power for your FAST modern pinball machine. We recommend this power supply for machines which powered by FAST Neuron controllers.

Note that prior to the Neuron release, we recommended a combination 12v/5v power supply. However the Neuron does not require 5V power, which is why we recommend this one instead. See the Neuron wiring guides for details.

See our guide Choosing a pinball machine power supply for details and reasons we selected this power supply.
