5. Setup and Installation
Before proceeding, ensure all power is disconnected from the circuit. Installation should only be performed by a qualified electrician or technician.
- Mounting: Secure the power supply to a stable, non-conductive surface using the mounting holes on its base. Ensure adequate space for ventilation.
- Input Wiring (Primary): Connect the AC 220V input power to the primary winding leads. Refer to the product label for specific primary connections (typically marked PRI). Ensure correct polarity and secure connections.
- Output Wiring (Secondary): Connect the desired output voltage leads to your power amplifier or other compatible device. The power supply offers multiple secondary windings to achieve different AC output voltages (e.g., 0V-18V-22V). Carefully identify the correct leads for your required voltage.
- Verification: Double-check all connections for tightness and correctness before applying power.

6. Operating Instructions
Once the power supply is correctly installed and wired:
- Apply Power: Connect the main power source to the input of the R50 60W power supply.
- Monitor: Observe the connected device for proper operation. The power supply should provide stable AC output voltage as configured.
- Normal Operation: The power supply is designed for continuous operation within its specified power range (55W-65W).
Note: The power supply may generate some heat during operation. This is normal, provided it remains within safe operating temperatures and has adequate ventilation.
7. Maintenance
The EQIMMFLJ R50 60W Power Supply requires minimal maintenance:
- Cleaning: Periodically clean the exterior of the unit with a dry, soft cloth to remove dust. Ensure power is disconnected before cleaning. Do not use liquid cleaners.
- Inspection: Regularly inspect the wiring for any signs of damage, fraying, or loose connections. Address any issues immediately.
- Ventilation: Ensure that ventilation openings are not obstructed to prevent overheating.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No output voltage | No input power; incorrect wiring; internal fault. | Check main power supply. Verify input and output wiring. If problem persists, discontinue use and contact support. |
| Output voltage is incorrect | Incorrect secondary winding connections; overloaded. | Review wiring diagram and ensure correct output leads are used. Check if the connected load exceeds 60W. |
| Unit is overheating | Insufficient ventilation; overloaded. | Ensure adequate airflow around the unit. Reduce the load if it exceeds 60W. |
| Unusual noise or smell | Internal component failure. | Immediately disconnect power. Do not attempt to operate. Contact support. |
