Cheyenne PU IV Professional Tattoo Power Supply

The Cheyenne Power Unit IV was developed in collaboration with professional tattoo artists to provide an ergonomic, intuitive, and space-efficient control solution.

Its output can be adjusted from 4.7 to 12.5 V in precise 0.1 V increments, with a maximum output power of 10 W. This operating range is suitable for all Cheyenne tattoo machines and is particularly well matched to the low-frequency performance of the SOL series.

The display can show machine output conventionally in volts or as a 30-step bar graph, with each step corresponding to approximately 0.26 V. An integrated stopwatch allows artists to monitor tattoo-session duration directly on the unit.

Two foot-switch modes support different working preferences:

• Latched mode: Press the pedal once to start the machine and again to stop it.
• Momentary mode: Keep the pedal pressed while operating the machine and release it to stop.

Magnetic rear and bottom panels allow the PU IV to attach securely to suitable metal surfaces. Its detachable stand also provides stable placement on a tabletop, making the unit easy to integrate into different workstation layouts.

Although optimised for Cheyenne equipment, the Power Unit IV can also operate compatible machines from other manufacturers when used with the appropriate connection.
