2. Sikkerhedsoplysninger
Læs alle instruktioner omhyggeligt før installation og betjening. Manglende overholdelse af disse instruktioner kan resultere i elektrisk stød, brand eller alvorlig personskade.
- Elektrisk fare: Ensure power is disconnected before installation or maintenance. Only qualified personnel should perform electrical connections.
- Ventilation: Sørg for tilstrækkelig luftgennemstrømning omkring enheden for at forhindre overophedning. Bloker ikke ventilationsåbningerne.
- Miljø: Install in a dry, well-ventilated area, free from excessive dust, moisture, and corrosive substances. Operate within specified temperature and humidity ranges.
- Jording: Proper grounding is essential for safety. Connect the protective earth (PE) terminal to a reliable ground.
- Output overbelastning: Do not exceed the rated output power. Overloading can damage the unit and pose a fire risk.
- Voltage Justering: Juster output voltage only when the unit is powered on and under no load, using a suitable insulated tool.
3. Opsætning og installation
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 Ledningsforbindelser
All connections are made via screw terminals. Refer to the labels on the unit for correct terminal identification.
Billede: Forside 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 justeringspotentiometer.
- 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.
- Udgang (DC): Connect the positive load wire to the "+V" terminal and the negative load wire to the "-V" terminal.
- Spænd terminalerne: Ensure all screw terminals are tightened securely to prevent loose connections and potential hazards.
Note: Use appropriate wire gauges for the current rating to avoid overheating.
4. Betjeningsvejledning
4.1 Tænd/sluk
- Once all connections are secure, apply input power to the unit.
- The "DC OK" indicator LED will illuminate when the output voltage er inden for det angivne område.
- To power off, disconnect the input power.
4.2 Udgang Voltage Justering
Output 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, mod uret for at mindske.
- Overvåg output voltage with a multimeter to ensure it is set to the desired level.
5. Vedligeholdelse
The MDR-60-24 power supply is designed for long-term, reliable operation with minimal maintenance. However, periodic checks are recommended:
- Rensning: Keep the unit clean and free from dust and debris. Use a soft, dry cloth for cleaning. Do not use liquid cleaners.
- Ventilation: Sørg for, at ventilationsåbningerne ikke blokeres.
- Forbindelser: Periodically check screw terminals for tightness, especially in environments with vibration.
- Miljøforhold: Kontroller, at driftsmiljøet holder sig inden for de angivne temperatur- og fugtighedsområder.

6. Fejlfinding
If the power supply is not functioning as expected, refer to the following troubleshooting guide:
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Ingen output voltage / DC OK LED off | Ingen indgangseffekt Input fuse blown Overbelastningsbeskyttelse aktiveret 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. |
| Udgang voltage for lav/høj | Voltage adjustment potentiometer incorrectly set Overbelastningstilstand | Adjust "V ADJ" potentiometer to desired voltage. Reducer belastningen. |
| Unit shuts down intermittently | Overtemperaturbeskyttelse aktiveret 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.
