1. Увод

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. Безбедносна упутства

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.
• Проверите да ли је улазна волtage range (90-264V AC) matches your local power supply.
• Обезбедите правилно уземљење да бисте спречили струјни удар.
• Не отварајте цasinг напајања. Унутра нема делова које корисник може сам да поправи.
• Одржавајте одговарајућу вентилацију око уређаја како бисте спречили прегревање.
• Use conductors rated for at least 75°C.
• Terminal torque for connections should be 5 Lb-in.

4. Подешавање и инсталација

4.1 Монтажа

1. Ensure the main power is OFF before mounting.
2. Mount the MDR-40-24 onto a standard TS-35/7.5 or TS-35/15 DIN rail.
3. Ensure sufficient clearance (at least 10mm on top and bottom, 5mm on sides) for proper ventilation.
4. The unit should be mounted vertically to allow for optimal heat dissipation through convection.

4.2 Ожичење

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
  • : Заштитно уземљење
• Output Terminals (DC):
  • +V: Positive DC output (24V)
  • -В: 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.

Напомена: Ensure all connections are secure and tightened to the specified torque of 5 Lb-in to prevent loose connections and potential hazards.

5. Упутство за употребу

5.1 Укључивање

1. After completing all wiring connections, switch on the main AC power supply.
2. The "DC OK" LED indicator on the front panel should illuminate, indicating normal operation.

5.2 Оутпут Волtagе Подешавање

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.
• Пратите излазну волtage with a multimeter to ensure it is within the desired range and does not exceed the maximum safe operating voltage for your connected devices.

Опрез: Не подешавајте излазну јачину звукаtage beyond the recommended range specified in the product datasheet to avoid damaging the power supply or connected equipment.

6. Одржавање

The MEAN WELL MDR-40-24 is designed for reliable operation and requires minimal maintenance.

• Чишћење: 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.
• вентилација: Ensure that the ventilation openings are not obstructed by dust or debris. Clear any blockages to maintain proper airflow.
• инспекција: Редовно проверавајте спојеве ожичења да ли постоје чврстоћа и знаци хабања или оштећења.
• Нема делова које корисник може сервисирати: Не покушавајте да отворите или поправите уређај. Све сервисне радове препустите квалификованом сервисеру.
