Power Supply

The power supply is the device that provides electrical energy to a corded machine, usually with adjustable voltage. It connects to the machine with a cord and a connector (for example RCA) and may include features such as a voltage display or a foot pedal.

Why it matters: For non-wireless machines, compatibility between power supply, cord and machine is essential. The characteristics should be checked in the manufacturer's instructions.
