Abstract
A power supply unit for a tattoo machine includes a power operating unit electrically connected to a power supply device. The power operating unit is electrically connected to an operating unit. The power operating unit can output a DC power and can control a current value or a voltage value of the DC power according to operation of the operating unit. A modulating unit is electrically connected to the power operating unit and the operating unit. The modulating unit modulates the DC power according to the operation of the operating unit and outputs a square wave power or the DC power. The modulating unit can control frequency or a work cycle of the square wave power according to the operation of the operating unit. An output end of the DC power supply unit is electrically connected to the tattoo machine to output the square wave power or the DC power.
