1. Pengenalan
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. Arahan Keselamatan
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.
- Sahkan bahawa input voltage range (90-264V AC) matches your local power supply.
- Pastikan pembumian yang betul untuk mengelakkan kejutan elektrik.
- Jangan buka casinbekalan kuasa. Tiada bahagian yang boleh diservis pengguna di dalamnya.
- Kekalkan pengudaraan yang mencukupi di sekitar unit untuk mengelakkan terlalu panas.
- Use conductors rated for at least 75°C.
- Terminal torque for connections should be 5 Lb-in.

- Output Terminals (DC):
- +V: Positive DC output (24V)
- -V: Negative DC output (0V / Ground)
- Hubungan Relay DC OK:
- 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. Arahan Operasi
5.1 Hidupkan
- 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 Keluaran Voltage Pelarasan
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.
- Pantau keluaran voltage with a multimeter to ensure it is within the desired range and does not exceed the maximum safe operating voltage for your connected devices.
Awas: Jangan laraskan vol keluarantage beyond the recommended range specified in the product datasheet to avoid damaging the power supply or connected equipment.
6. Penyelenggaraan
The MEAN WELL MDR-40-24 is designed for reliable operation and requires minimal maintenance.
- Pembersihan: 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.
- Pengudaraan: Ensure that the ventilation openings are not obstructed by dust or debris. Clear any blockages to maintain proper airflow.
- Pemeriksaan: Regularly inspect wiring connections for tightness and signs of wear or damage.
- Tiada Bahagian Boleh Servis Pengguna: Jangan cuba membuka atau membaiki unit. Rujuk semua servis kepada kakitangan perkhidmatan yang berkelayakan.
