5. Setup
5.1 Input Voltage Selection
Before connecting the power supply to an AC source, you must select the correct input voltage (110V or 220V) using the switch located inside the unit. For users in the USA, set the switch to 110V.
Figure 5: This image shows the internal voltage selector switch. The top panel indicates the switch location, and the bottom panel provides a close-up of the switch, which must be set to 110V for use in the USA.
5.2 Wiring Instructions
The power supply features a terminal block for secure wiring connections. Refer to the diagram below for proper connection of AC input and DC output.
- AC Input: Connect the Live (L) and Neutral (N) wires from your AC power source to the corresponding terminals. Ensure the Earth wire is connected to the ground terminal.
- DC Output: Connect the positive (+V) wire of your device to the +V terminal and the negative (-V) wire to the -V terminal.

5.3 Mounting
Mount the power supply in a location that allows for adequate ventilation and prevents obstruction of the cooling fan and ventilation slots. Ensure the mounting surface is stable and non-conductive.
6. Operating Instructions
6.1 Initial Power-Up
After ensuring all connections are secure and the voltage switch is correctly set, connect the power supply to the AC mains. The unit should power on, and the cooling fan may activate depending on the load and internal temperature.
6.2 Output Voltage Regulation
The power supply includes a potentiometer for fine-tuning the output voltage. Use a small screwdriver to adjust this control if minor voltage adjustments are required. Always verify the output voltage with a multimeter to ensure it meets your application's requirements.
7. Maintenance
The inShareplus power supply is designed for minimal maintenance. However, periodic checks can help ensure its longevity and reliable operation.
- Cleaning: Periodically clean the exterior of the unit and ensure ventilation slots are free from dust and debris. Use a soft, dry cloth. Do not use liquid cleaners.
- Fan Operation: The built-in cooling fan operates to maintain optimal temperature. Ensure it is not obstructed and is functioning correctly. A noisy fan might indicate dust buildup or wear.
- Connection Integrity: Occasionally check all wiring connections to ensure they remain tight and secure.
8. Troubleshooting
If you encounter issues with your power supply, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power output | 1. Incorrect input voltage selection. 2. Loose wiring connections. 3. Overload protection activated. 4. Internal fault. | 1. Verify the 110V/220V switch setting. 2. Check all input and output wiring. 3. Reduce the connected load. Disconnect power, wait, then reconnect. 4. Contact support if other solutions fail. |
| Output voltage is incorrect | 1. Output voltage potentiometer misadjusted. 2. Connected load is too high. | 1. Adjust the output voltage potentiometer with a multimeter. 2. Ensure the load does not exceed 80% of the rated power. |
| Unit is overheating | 1. Insufficient ventilation. 2. Excessive load. 3. Fan malfunction. | 1. Ensure clear airflow around the unit. 2. Reduce the connected load. 3. Check if the fan is spinning freely. Clean if necessary. |
| Loud fan noise | 1. Dust buildup in fan. 2. Fan bearing wear. | 1. Disconnect power and carefully clean the fan blades. 2. If noise persists, contact support. |
Important: If troubleshooting steps do not resolve the issue, discontinue use and contact customer support.
