The rear panel features the AC power input socket for the power cord, a fuse holder, and a label with input/output specifications and certification marks.
5. Setup Instructions
- Placement: Place the power supply on a stable, flat surface in a well-ventilated area. Ensure there is sufficient space around the unit for air circulation.
- Power Connection:
- Ensure the ON/OFF switch on the front panel is in the "OFF" position.
- Connect the provided AC power cord to the AC input socket on the rear panel of the power supply.
- Plug the other end of the AC power cord into a standard grounded 120V AC wall outlet.
- Output Connection:
- Connect your device's positive lead (typically red) to the red (+) banana plug terminal on the power supply.
- Connect your device's negative lead (typically black) to the black (-) banana plug terminal on the power supply.
- Ensure all connections are secure to prevent intermittent power or short circuits.
6. Operating Instructions
- Power On: Flip the ON/OFF switch on the front panel to the "ON" position. The LED digital display will illuminate, showing the current output voltage.
- Adjusting Voltage:
- Rotate the voltage adjustment knob clockwise to increase the output voltage.
- Rotate the voltage adjustment knob counter-clockwise to decrease the output voltage.
- Observe the LED display to set the desired voltage between 1.5V and 15V.
- Using with a Device: Once the desired voltage is set, the connected device will receive power. The power supply provides a fixed 2 Amps of current.
- Power Off: When finished, flip the ON/OFF switch to the "OFF" position. Disconnect the power cord from the wall outlet if the unit will not be used for an extended period.
Note: For tattoo machine applications, the speed of the machine is directly controlled by the voltage setting. Higher voltage results in higher speed.
7. Maintenance
- Cleaning: Disconnect the power supply from the AC outlet before cleaning. Use a soft, dry cloth to wipe the exterior of the unit. Do not use liquid cleaners or solvents.
- Ventilation: Periodically check that the ventilation openings are free from dust and debris. Use compressed air if necessary to clear any blockages.
- Storage: Store the power supply in a cool, dry place away from direct sunlight and extreme temperatures when not in use.
- Fuse Replacement: If the unit fails to power on, the fuse may need replacement.
- Disconnect the power cord from the wall outlet.
- Locate the fuse holder on the rear panel.
- Carefully unscrew the fuse holder cap.
- Replace the blown fuse with a new fuse of the same type and rating (2A, F).
- Screw the fuse holder cap back into place.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Power supply does not turn on. | No AC power; Blown fuse; Faulty power cord. | Check AC outlet and power cord connection. Replace fuse (see Maintenance section). Try a different power cord. |
| No output voltage. | Output connections loose; Voltage knob set to minimum; Internal fault. | Ensure output leads are securely connected. Adjust voltage knob. If problem persists, contact support. |
| Output voltage is unstable or incorrect. | Loose connections; Overload; Internal fault. | Check all connections. Ensure connected device does not draw more than 2 Amps. Contact support if issue continues. |
| Unit feels excessively hot. | Poor ventilation; Overload. | Ensure ventilation openings are clear. Reduce load on the power supply. Discontinue use if overheating persists and contact support. |
