1. Inleiding
This manual provides essential information for the safe and efficient operation of the MEAN WELL MDR-60-24 DIN Rail Power Supply. The MDR-60-24 is an industrial-grade switching power supply designed for reliable 24V DC power delivery in various applications.
Sleutel kenmerke:
- 60W output power (24V at 2.5A continuous current).
- High efficiency (87% typical).
- Universal 85-264VAC / 120-370VDC input voltage verenigbaarheid.
- Verstelbare uitset voltage reeks (24V tot 30V).
- Ingeboude oor-voltage, over-load, short-circuit, and over-temperature protection.
- Compact metal housing with IP20 protection.
- DIN rail mountable for easy installation.
- Safety-certified with CE, RoHS, and UL60950-1 compliance.
2. Veiligheidsinligting
Read all instructions carefully before installation and operation. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- Elektriese gevaar: Ensure power is disconnected before installation or maintenance. Only qualified personnel should perform electrical connections.
- Ventilasie: Verseker voldoende lugvloei rondom die eenheid om oorverhitting te voorkom. Moenie ventilasie-openinge blokkeer nie.
- Omgewing: Install in a dry, well-ventilated area, free from excessive dust, moisture, and corrosive substances. Operate within specified temperature and humidity ranges.
- Aarding: Proper grounding is essential for safety. Connect the protective earth (PE) terminal to a reliable ground.
- Uitset oorlaai: Do not exceed the rated output power. Overloading can damage the unit and pose a fire risk.
- Voltage Aanpassing: Pas die uitset voltage only when the unit is powered on and under no load, using a suitable insulated tool.
3. Opstelling en installering
The MDR-60-24 is designed for DIN rail mounting (TS-35/7.5 or TS-35/15). Follow these steps for installation:
3.1 Montering
- Ensure the DIN rail is securely installed in a suitable enclosure.
- Hook the top edge of the power supply onto the DIN rail.
- Push the bottom of the power supply firmly until it clicks into place on the DIN rail.
- Verify the unit is securely attached and cannot be easily dislodged.

3.2 Bedradingsverbindings
All connections are made via screw terminals. Refer to the labels on the unit for correct terminal identification.
Beeld: Voorkant view of the MDR-60-24 power supply, clearly showing the input (L, N, PE) and output (+V, -V) screw terminals, along with the DC OK indicator and voltage verstellingspotensiometer.
- Input (AC/DC): Connect the AC input (Line, Neutral) or DC input to the "L" and "N" terminals. Connect the protective earth to the "PE" terminal. Ensure correct polarity for DC input.
- Uitset (DC): Connect the positive load wire to the "+V" terminal and the negative load wire to the "-V" terminal.
- Tighten Terminals: Ensure all screw terminals are tightened securely to prevent loose connections and potential hazards.
Let wel: Gebruik gepaste draaddiktes vir die stroomgradering om oorverhitting te voorkom.
4. Bedryfsinstruksies
4.1 Krag aan/af
- Once all connections are secure, apply input power to the unit.
- The "DC OK" indicator LED will illuminate when the output voltage is binne die gespesifiseerde reeks.
- To power off, disconnect the input power.
4.2 Uitset Voltage Aanpassing
Die uitset voltage can be adjusted from 24V to 30V using the potentiometer located on the front panel.
- With the unit powered on and under no load, use a small, insulated screwdriver to carefully turn the "V ADJ" potentiometer.
- Turn clockwise to increase the voltage, counter-clockwise to decrease.
- Monitor die uitset voltage with a multimeter to ensure it is set to the desired level.
5. Onderhoud
The MDR-60-24 power supply is designed for long-term, reliable operation with minimal maintenance. However, periodic checks are recommended:
- Skoonmaak: Keep the unit clean and free from dust and debris. Use a soft, dry cloth for cleaning. Do not use liquid cleaners.
- Ventilasie: Maak seker dat ventilasie openinge nie versper word nie.
- Verbindings: Periodically check screw terminals for tightness, especially in environments with vibration.
- Omgewingstoestande: Verifieer dat die bedryfsomgewing binne die gespesifiseerde temperatuur- en humiditeitsreekse bly.

6. Probleemoplossing
If the power supply is not functioning as expected, refer to the following troubleshooting guide:
| Probleem | Moontlike oorsaak | Oplossing |
|---|---|---|
| Geen uitset voltage / DC OK LED off | Geen insetkrag nie Input fuse blown Oorladingsbeskerming geaktiveer Short-circuit protection activated | Check input power source and connections. Replace fuse (if accessible and cause identified). Reduce load. Disconnect and reconnect power. Check for short circuits in the load. Disconnect and reconnect power. |
| Uitset voltage te laag/hoog | Voltage adjustment potentiometer incorrectly set Oorladingstoestand | Adjust "V ADJ" potentiometer to desired voltage. Verminder vrag. |
| Unit shuts down intermittently | Oortemperatuurbeskerming geaktiveer Intermittent overload | Ensure adequate ventilation and ambient temperature. Reduce load. Check load for intermittent spikes or faults. |
If the problem persists after following these steps, contact technical support.
