Compact tattoo power supply designed for precise control, reliable protection, and flexible operation with standard tattoo machines and foot pedals. Key benefits Flexible control modes: choose a continuous Working Mode when you want the machine to run without holding the foot pedal, or a pedalcontrolled mode for full manual control. Precise voltage adjustment: fine tuning at 0.1 V increments lets you match performance to needles, inks, and techniques. Wide input range for international use: supports 100230 V AC. Builtin safety and energy savings: automatic sleep and overload protection reduce wear and power draw, increasing reliability. Main features Two operation modes: Press once: red indicator lights and the unit remains in Working Mode so the foot pedal does not need to be held. Press twice: red indicator goes off and the unit requires continuous foot pedal control to operate. Easy voltage control: rotate the control knob clockwise to raise voltage and counterclockwise to lower it. Each adjustment changes output by 0.1 V for accurate tuning. No mechanical power switch: after five minutes of inactivity the unit automatically enters sleep mode to cut consumption. Rotate or press the control knob or activate the foot pedal to resume Working Mode immediately. Overcurrent protection: the power supply automatically powers off in the event of abnormal current to protect against overload damage and help extend service life. Performance and compatibility Input voltage: 100230 V AC for use in a variety of settings. Output adjustment resolution: 0.1 V steps for precise performance control. Compatible with standard tattoo machines and foot pedal setups. Practical use scenarios Tattoo studio sessions: set the unit to Working Mode for uninterrupted shading or lining when you prefer not to hold the foot pedal continuously. Mobile or convention setups: use sleep mode to save power between appointments and quickly resume work by rotating the knob or pressing the pedal. Training and practice: switch to pedalcontrolled mode to simulate clientcontrolled starts and stops while learning hand and foot coordination. This power supply focuses on dependable operation, precise control, and protective features to support consistent tattoo work in studio, mobile, and training environments.
