2. Informació de seguretat
Llegiu atentament totes les instruccions abans de la instal·lació i el funcionament. Si no seguiu aquestes instruccions, podeu patir descàrregues elèctriques, incendis o lesions greus.
- Risc elèctric: Assegureu-vos que l'alimentació estigui desconnectada abans de la instal·lació o el manteniment. Només personal qualificat ha de realitzar les connexions elèctriques.
- Ventilació: Assegureu-vos que hi hagi un flux d'aire adequat al voltant de la unitat per evitar el sobreescalfament. No bloquegeu les obertures de ventilació.
- Medi ambient: Install in a dry, well-ventilated area, free from excessive dust, moisture, and corrosive substances. Operate within specified temperature and humidity ranges.
- Posada a terra: Proper grounding is essential for safety. Connect the protective earth (PE) terminal to a reliable ground.
- Sobrecàrrega de sortida: Do not exceed the rated output power. Overloading can damage the unit and pose a fire risk.
- Voltage Ajust: Ajusteu el volum de sortidatage only when the unit is powered on and under no load, using a suitable insulated tool.
3. Configuració i instal·lació
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 Muntatge
- Ensure the DIN rail is securely installed in a suitable enclosure.
- Enganxeu la vora superior de la font d'alimentació al carril DIN.
- 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 Connexions de cablejat
All connections are made via screw terminals. Refer to the labels on the unit for correct terminal identification.
Imatge: Frontal 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 potenciòmetre d'ajust.
- 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.
- Sortida (DC): Connect the positive load wire to the "+V" terminal and the negative load wire to the "-V" terminal.
- Estreny els terminals: Ensure all screw terminals are tightened securely to prevent loose connections and potential hazards.
Nota: Use appropriate wire gauges for the current rating to avoid overheating.
4. Instruccions de funcionament
4.1 Encès/Apagat
- Once all connections are secure, apply input power to the unit.
- The "DC OK" indicator LED will illuminate when the output voltage està dins de l'interval especificat.
- To power off, disconnect the input power.
4.2 Vol. de sortidatage Ajust
El 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.
- Monitoritzar el volum de sortidatage with a multimeter to ensure it is set to the desired level.
5. Manteniment
The MDR-60-24 power supply is designed for long-term, reliable operation with minimal maintenance. However, periodic checks are recommended:
- Neteja: Mantingueu la unitat neta i lliure de pols i deixalles. Feu servir un drap suau i sec per netejar-la. No utilitzeu netejadors líquids.
- Ventilació: Assegureu-vos que les obertures de ventilació no estiguin obstruïdes.
- Connexions: Periodically check screw terminals for tightness, especially in environments with vibration.
- Condicions ambientals: Verifiqueu que l'entorn operatiu es mantingui dins dels rangs de temperatura i humitat especificats.

6. Solució De Problemes
If the power supply is not functioning as expected, refer to the following troubleshooting guide:
| Problema | Causa possible | Solució |
|---|---|---|
| Sense sortida voltage / DC OK LED off | Sense potència d'entrada Input fuse blown Protecció de sobrecàrrega activada Protecció contra curtcircuits activada | 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. |
| Volum de sortidatagmassa baix/alt | Voltage adjustment potentiometer incorrectly set Condició de sobrecàrrega | Adjust "V ADJ" potentiometer to desired voltage. Reduir la càrrega. |
| La unitat s'apaga de manera intermitent | Protecció de sobretemperatura activada 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.
