4.2 Wiring Connections
Before making any connections, ensure the main power supply is OFF.
| Terminal | Description |
|---|---|
| N | AC Neutral Input |
| L | AC Line Input |
| ⌂ | Ground (Earth) |
| +V | DC Output Positive |
| -V | DC Output Negative |
Connect the AC input wires to the 'N' and 'L' terminals. Connect the ground wire to the ground terminal. Connect your load to the '+V' and '-V' terminals, ensuring correct polarity. Use appropriate wire gauges for the current requirements.
5. Operating Instructions
Once properly installed and wired, the DR-60-24 power supply operates automatically upon receiving AC input power.
- Power On: Apply AC power to the input terminals. The "DC OK" indicator LED (if present, typically green) should illuminate, indicating stable DC output.
- Output Voltage Adjustment: The DR-60-24 may have a small potentiometer (labeled "ADJ" or similar) for fine-tuning the output voltage. Use a small screwdriver to adjust if necessary, staying within the specified voltage range.
- Overload Protection: If the output current exceeds the rated value (2.5A), the unit's overload protection will activate, potentially shutting down the output or limiting current. Remove the overload condition, and the unit should recover automatically.
6. Maintenance
The Mean Well DR-60-24 power supply is designed for long-term, reliable operation with minimal maintenance.
- Cleaning: Periodically clean the exterior of the unit with a soft, dry cloth. Do not use liquid cleaners or solvents. Ensure power is disconnected before cleaning.
- Ventilation: Ensure that the ventilation openings are not obstructed by dust or debris. Proper airflow is crucial for heat dissipation.
- Connections: Periodically check all wiring connections to ensure they are secure and free from corrosion.
No user-serviceable parts are inside. Do not attempt to open or repair the unit.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No output voltage / "DC OK" LED off | No AC input power Input fuse blown Overload/Short circuit on output | Check AC power source and connections. Consult qualified electrician for fuse replacement. Disconnect load, check for short circuit, then reconnect. |
| Output voltage too low or unstable | Overload condition Loose connections Faulty unit | Reduce load. Check and tighten all wiring connections. Contact customer support if problem persists. |
| Unit is hot to the touch | Insufficient ventilation Ambient temperature too high Overload | Ensure proper airflow around the unit. Operate within specified temperature range. Reduce load. |
If you encounter issues not listed here or if the problem persists after attempting the solutions, please contact Mean Well customer support or a qualified technician.
