2. Arahan Keselamatan
Always adhere to the following safety precautions to prevent electric shock, fire, or damage to the device:
- Ensure the power supply is connected to a grounded outlet with the correct voltage (AC 230V).
- Jangan kendalikan peranti dalam keadaan basah atau damp syarat.
- Jangan buka casing; tiada bahagian yang boleh diservis oleh pengguna di dalamnya. Rujuk semua servis kepada kakitangan yang berkelayakan.
- Elakkan litar pintas terminal output.
- Ensure proper ventilation; do not block the ventilation openings.
- Disconnect the power cord before cleaning or moving the unit.
- Use only the specified fuse type (F5A250VAC).

- Kipas Penyejuk: Provides necessary airflow to dissipate heat.
- Input Kuasa AC: IEC C14 connector for the power cord.
- Pemegang fius: Contains the main protective fuse (F5A250VAC).
4. Persediaan
- Membongkar: Carefully remove the power supply from its packaging. Inspect for any signs of damage during transit. Retain the packaging for future transport or storage.
- penempatan: Place the unit on a stable, level surface. Ensure there is adequate space around the unit (at least 10 cm on all sides) for proper ventilation, especially around the rear cooling fan. Avoid placing it near heat sources or in direct sunlight.
- Sambungan Kuasa: Connect the supplied AC power cord to the AC power input on the rear panel of the power supply and then to a grounded AC 230V wall outlet.
- Semakan Awal: Before connecting any load, turn on the power supply using the front panel power switch. The digital display should illuminate, showing voltage dan bacaan semasa.
5. Arahan Operasi
5.1 Menghidupkan dan Mematikan
- To turn on, press the power switch on the front panel to the 'ON' (I) position.
- To turn off, press the power switch to the 'OFF' (O) position.
5.2 Adjusting Voltage dan Semasa
- Tetapan Voltage: Rotate the 'VOLT Coarse' knob to set the approximate desired voltage. Use the 'VOLT Fine' knob for precise adjustments. Observe the voltage reading on the digital display.
- Menetapkan Had Semasa: Rotate the 'CURR Coarse' knob to set the approximate maximum current limit. Use the 'CURR Fine' knob for precise adjustments. This setting determines the maximum current the power supply will deliver before switching to Constant Current (C.C.) mode.
- Understanding CV/CC Modes:
- Pemalar Voltage (C.V.): When the load resistance is high enough that the current drawn is less than the set current limit, the power supply operates in C.V. mode, maintaining the set voltage. The C.V. indicator will be lit.
- Constant Current (C.C.): When the load resistance is low, causing the current drawn to reach the set current limit, the power supply switches to C.C. mode. The output voltage will drop to maintain the set current. The C.C. indicator will be lit.
5.3 Connecting a Load
- Ensure the power supply is turned off before connecting any load.
- Connect the positive (+) terminal of your load to the red output terminal of the power supply.
- Connect the negative (-) terminal of your load to the black output terminal of the power supply.
- If your load requires grounding, connect its ground terminal to the green/yellow output terminal of the power supply.
- After connecting the load, turn on the power supply. Adjust voltage and current as required for your application.
6. Penyelenggaraan
- Pembersihan: Putuskan sambungan bekalan kuasa daripada sesalur kuasa sebelum membersihkan. Gunakan kain lembut dan kering untuk mengelap bahagian luar. Jangan gunakan pembersih atau pelarut yang kasar.
- Pengudaraan: Regularly check that the ventilation openings and cooling fan are free from dust and debris. Use compressed air to clear any blockages if necessary.
- Penggantian fius: If the unit fails to power on, the fuse may need replacement. Disconnect the power cord, locate the fuse holder on the rear panel, and replace the fuse with one of the identical type and rating (F5A250VAC).
- Storan: Apabila tidak digunakan untuk tempoh yang lama, simpan bekalan kuasa di tempat yang sejuk dan kering, jauh daripada cahaya matahari langsung dan suhu yang melampau.
