3. Package Contents
Verify that all items are present in the package:
- 1 x TDK-Lambda DPP15-24 DIN Rail Power Supply
- 1 x User Manual (this document)
4. Setup and Installation
The DPP15-24 is designed for mounting on a standard DIN rail (TS-35/7.5 or TS-35/15).
4.1 Mounting
- Ensure the DIN rail is securely fastened within the enclosure.
- Hook the top edge of the power supply onto the DIN rail.
- Push the bottom edge of the power supply firmly until it clicks into place on the DIN rail.
- Verify the unit is securely mounted and does not wobble.
4.2 Wiring Connections
Refer to the terminal block labels on the unit for correct wiring. Use appropriate wire gauges for the current requirements.

- Input (AC/DC): Connect the AC Line (L), Neutral (N), and Earth (PE) wires to the corresponding input terminals. For DC input, connect the positive DC to 'L' and negative DC to 'N'.
- Output (DC): Connect the positive (+) load wire to the '+V' terminal and the negative (-) load wire to the '-V' terminal.
5. Operating Instructions
5.1 Powering On
After all connections are securely made and verified, apply power to the input terminals. The green 'DC OK' LED indicator on the front panel will illuminate, indicating that the output voltage is within the specified range.
5.2 Output Voltage Adjustment
The output voltage can be finely adjusted using the potentiometer located on the front panel. Use a small, insulated screwdriver to turn the potentiometer clockwise to increase the voltage and counter-clockwise to decrease it. Always monitor the output voltage with a multimeter during adjustment to ensure it remains within the safe operating limits of your connected devices.
6. Maintenance
The DPP15-24 power supply is designed for long-term, reliable operation with minimal maintenance. However, periodic checks are recommended.
- Cleaning: Ensure the ventilation openings are free from dust and debris. If cleaning is necessary, disconnect power and use a soft, dry cloth. Do not use liquid cleaners.
- Connections: Periodically check all wiring connections for tightness. Loose connections can lead to poor performance or safety hazards.
- Environment: Verify that the operating environment remains within the specified temperature and humidity ranges.
7. Troubleshooting
If you encounter issues with your DPP15-24 power supply, refer to the following table:
| Problem | Possible Cause | Solution |
|---|---|---|
| No output voltage / DC OK LED off | No input power; Incorrect wiring; Internal fault; Overload/Short circuit | Check input power source and connections; Verify wiring polarity; Disconnect load to check for short circuit; If problem persists, contact support. |
| Output voltage unstable or incorrect | Load too high; Poor connections; Adjustment potentiometer setting | Reduce load; Check and tighten all connections; Adjust output voltage potentiometer carefully. |
| Unit is hot to the touch | Insufficient ventilation; Overload | Ensure adequate airflow around the unit; Reduce load if it exceeds specifications. |
If the issue cannot be resolved using the troubleshooting guide, do not attempt to repair the unit yourself. Contact qualified service personnel or TDK-Lambda support.
