5. Setup and Installation
The GLOGLOW DR-30-12 is designed for easy installation on a standard DIN rail. Follow these steps for proper setup:
- Mounting: Securely attach the power supply to a standard DIN rail. Ensure it clicks into place firmly.
- Input Wiring (AC):
- Connect the Live (L) wire of your AC power source to the 'L' terminal on the power supply.
- Connect the Neutral (N) wire of your AC power source to the 'N' terminal on the power supply.
- Connect the Ground (PE) wire to the ground terminal (indicated by the ground symbol) on the power supply.
WARNING: Ensure all connections are tight and secure to prevent loose contacts and potential hazards.
- Output Wiring (DC):
- Connect the positive (+) terminal of your DC load to the '+V' terminal on the power supply.
- Connect the negative (-) terminal of your DC load to the '-V' terminal on the power supply.
- Ventilation: Ensure sufficient clearance around the power supply for proper heat dissipation. Do not obstruct the hollow shell design.

6. Operating Instructions
Once properly installed and wired, the GLOGLOW DR-30-12 is ready for operation.
- Power On: Apply AC power to the input terminals (L, N). The 'DC OK' indicator LED should illuminate, indicating proper operation.
- Output Voltage Adjustment: If necessary, the output voltage can be finely adjusted using the 'ADJ' potentiometer located on the top of the unit. Use a small screwdriver to turn the potentiometer clockwise to increase voltage or counter-clockwise to decrease voltage within the specified range.
- Monitoring: The 'DC OK' LED provides a visual indication of the output status. If the LED is off, check the input power and output load.

7. Maintenance
The GLOGLOW DR-30-12 Switching Power Supply requires minimal maintenance.
- Cleaning: Periodically clean the exterior of the unit with a soft, dry cloth. Do not use liquid cleaners or solvents. Ensure the unit is powered off and disconnected before cleaning.
- Ventilation: Regularly check that the ventilation openings are free from dust and obstructions to ensure optimal heat dissipation.
- Connections: Periodically inspect all wiring connections to ensure they remain tight and secure.
- Do Not Open: As stated in the safety warnings, do not attempt to open the casing of the power supply. There are no user-serviceable parts inside, and opening it poses a risk of electric shock.
8. Troubleshooting
If you encounter issues with your power supply, refer to the following troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| No output power / DC OK LED off | No AC input power Loose wiring connections Overload or short circuit on output | Check AC power source and circuit breaker. Verify all input and output wiring connections are secure. Disconnect load and check for short circuits. Reduce load if overloaded. |
| Output voltage unstable or incorrect | ADJ potentiometer incorrectly set Fluctuating input voltage Overload condition | Adjust the 'ADJ' potentiometer to the desired voltage. Ensure stable AC input voltage. Reduce the load to within the 30W limit. |
| Unit is excessively hot | Insufficient ventilation Overload condition | Ensure adequate airflow around the unit and clear any obstructions. Reduce the load to prevent overheating. |
If the problem persists after attempting these solutions, contact customer support. Do not attempt to repair the unit yourself.
