2. Maklumat Keselamatan
Baca semua arahan dengan teliti sebelum pemasangan dan pengendalian. Kegagalan mematuhi arahan ini boleh mengakibatkan renjatan elektrik, kebakaran atau kecederaan serius.
- Bahaya Elektrik: Ensure power is disconnected before installation or maintenance. Only qualified personnel should perform electrical connections.
- Pengudaraan: Pastikan aliran udara yang mencukupi di sekeliling unit untuk mengelakkan terlalu panas. Jangan sekat bukaan pengudaraan.
- Persekitaran: Install in a dry, well-ventilated area, free from excessive dust, moisture, and corrosive substances. Operate within specified temperature and humidity ranges.
- Pembumian: Proper grounding is essential for safety. Connect the protective earth (PE) terminal to a reliable ground.
- Beban Keluaran: Do not exceed the rated output power. Overloading can damage the unit and pose a fire risk.
- Voltage Pelarasan: Laraskan keluaran voltage only when the unit is powered on and under no load, using a suitable insulated tool.
3. Persediaan dan Pemasangan
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 Pemasangan
- Ensure the DIN rail is securely installed in a suitable enclosure.
- Cangkukkan tepi atas bekalan kuasa pada rel 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 Sambungan Pendawaian
All connections are made via screw terminals. Refer to the labels on the unit for correct terminal identification.
Imej: Depan 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 potensiometer pelarasan.
- 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.
- Output (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.
Nota: Use appropriate wire gauges for the current rating to avoid overheating.
4. Arahan Operasi
4.1 Hidupkan/Mati Kuasa
- Once all connections are secure, apply input power to the unit.
- The "DC OK" indicator LED will illuminate when the output voltage berada dalam julat yang ditetapkan.
- To power off, disconnect the input power.
4.2 Keluaran Voltage Pelarasan
Keluaran 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, lawan arah jam untuk berkurangan.
- Pantau keluaran voltage with a multimeter to ensure it is set to the desired level.
5. Penyelenggaraan
The MDR-60-24 power supply is designed for long-term, reliable operation with minimal maintenance. However, periodic checks are recommended:
- Pembersihan: Keep the unit clean and free from dust and debris. Use a soft, dry cloth for cleaning. Do not use liquid cleaners.
- Pengudaraan: Pastikan bukaan pengudaraan tidak terhalang.
- Sambungan: Periodically check screw terminals for tightness, especially in environments with vibration.
- Keadaan Persekitaran: Sahkan bahawa persekitaran operasi kekal dalam julat suhu dan kelembapan yang ditetapkan.

6. Penyelesaian masalah
If the power supply is not functioning as expected, refer to the following troubleshooting guide:
| Masalah | Kemungkinan Punca | Penyelesaian |
|---|---|---|
| Tiada keluaran voltage / DC OK LED off | Tiada kuasa input Input fuse blown Perlindungan beban lampau diaktifkan 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. |
| Keluaran voltage terlalu rendah/tinggi | Voltage adjustment potentiometer incorrectly set Keadaan beban berlebihan | Adjust "V ADJ" potentiometer to desired voltage. Kurangkan beban. |
| Unit shuts down intermittently | Perlindungan lebih suhu diaktifkan Intermittent overload | Ensure adequate ventilation and ambient temperature. Reduce load. Check load for intermittent spikes or faults. |
Jika masalah berterusan selepas mengikuti langkah-langkah ini, hubungi sokongan teknikal.
