1. Introducció
This manual provides essential information for the safe and efficient installation, operation, and maintenance of the MEAN WELL MDR-40-24 DIN Rail Power Supply. Please read this manual thoroughly before using the product and retain it for future reference.
The MDR-40-24 is a 40W single output industrial DIN rail power supply, designed for installation on TS-35/7.5 or TS-35/15 standard DIN rails. It provides a stable 24V DC output with a current rating of 1.74A.
2. Instruccions de seguretat
WARNING: Risk of electric shock and fire. Installation must be performed by qualified personnel only.
- Ensure the power supply is disconnected from the main AC input before any installation, wiring, or maintenance work.
- Do not operate the unit in environments with high humidity, extreme temperatures, or corrosive substances.
- Comproveu que l'entrada voltage range (90-264V AC) matches your local power supply.
- Assegureu-vos de posar a terra adequadament per evitar descàrregues elèctriques.
- No obriu la c.asing de la font d'alimentació. No hi ha peces que l'usuari pugui reparar a l'interior.
- Mantingueu una ventilació adequada al voltant de la unitat per evitar el sobreescalfament.
- Use conductors rated for at least 75°C.
- Terminal torque for connections should be 5 Lb-in.

4. Configuració i instal·lació
4.1 Muntatge
- Ensure the main power is OFF before mounting.
- Mount the MDR-40-24 onto a standard TS-35/7.5 or TS-35/15 DIN rail.
- Ensure sufficient clearance (at least 10mm on top and bottom, 5mm on sides) for proper ventilation.
- The unit should be mounted vertically to allow for optimal heat dissipation through convection.
4.2 Connexions de cablejat
Refer to the markings on the unit for correct terminal connections. Use appropriate wire gauges for the current rating.
- Input Terminals (AC):
- L: Live AC input
- N: Neutral AC input
: Terra protectora de la terra
- Output Terminals (DC):
- +V: Positive DC output (24V)
- -V: Negative DC output (0V / Ground)
- DC OK Relay Contact:
- Provides a signal indicating the DC output status. Refer to the product datasheet for detailed relay specifications.
Nota: Ensure all connections are secure and tightened to the specified torque of 5 Lb-in to prevent loose connections and potential hazards.
5. Instruccions de funcionament
5.1 Encès
- After completing all wiring connections, switch on the main AC power supply.
- The "DC OK" LED indicator on the front panel should illuminate, indicating normal operation.
5.2 Vol. de sortidatage Ajust
The MDR-40-24 features a potentiometer labeled "+V ADJ" on the front panel for fine-tuning the output voltage.
- Using a small screwdriver, carefully turn the potentiometer clockwise to increase the output voltage or counter-clockwise to decrease it.
- Monitoritzar el volum de sortidatage with a multimeter to ensure it is within the desired range and does not exceed the maximum safe operating voltage per als vostres dispositius connectats.
Precaució: No ajusteu el volum de sortidatage beyond the recommended range specified in the product datasheet to avoid damaging the power supply or connected equipment.
6. Manteniment
The MEAN WELL MDR-40-24 is designed for reliable operation and requires minimal maintenance.
- Neteja: 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.
- Ventilació: Ensure that the ventilation openings are not obstructed by dust or debris. Clear any blockages to maintain proper airflow.
- Inspecció: Inspeccioneu regularment les connexions del cablejat per comprovar si estan ben ajustades i si hi ha signes de desgast o danys.
- No hi ha peces reparables per l'usuari: No intenteu obrir ni reparar la unitat. Envieu totes les tasques de manteniment a personal de servei qualificat.
