2. Arahan Keselamatan
Please read and understand all safety instructions before operating the power supply. Failure to follow these instructions may result in electric shock, fire, or damage to the unit.
- Sumber Kuasa: Connect the power supply only to a grounded AC outlet with the correct voltage (115V or 230V, ensure the voltage selector switch on the rear panel is set correctly).
- Pengudaraan: Ensure adequate ventilation around the unit. Do not block the cooling fan or ventilation openings. Maintain at least 10 cm (4 inches) of clear space around the unit.
- Persekitaran: Do not operate the power supply in damp, wet, or explosive environments. Avoid direct sunlight and high temperatures.
- Lebihan beban: Jangan melebihi nilai keluaran voltage or current. Operating the unit beyond its specifications can cause damage.
- Penyelenggaraan: Jangan cuba menservis unit ini sendiri. Rujuk semua servis kepada kakitangan yang berkelayakan.
- Sambungan: Ensure all connections are secure before applying power. Disconnect power before making or changing connections.

5. Arahan Operasi
5.1 Adjusting Voltage dan Semasa
- Hidupkan kuasa: Pastikan bekalan kuasa dihidupkan.
- Set Voltage: Use the V-COARSE and V-FINE knobs to set the desired output voltage. Voltage Display will show the set value.
- Tetapkan Had Semasa: Use the A-COARSE and A-FINE knobs to set the desired current limit. This is the maximum current the power supply will deliver. It is recommended to set the current limit slightly above the expected operating current of your load to prevent accidental overcurrent.
- Pemalar VoltagMod e (CV): Apabila keluaran voltage is stable and the current drawn by the load is below the set current limit, the C.V. indicator will be lit. The power supply will maintain the set voltage.
- Mod Arus Malar (CC): If the load resistance is too low or the load attempts to draw more current than the set limit, the power supply will automatically switch to Constant Current mode. The C.C. indicator will be lit, and the output current will be maintained at the set limit, while the output voltage akan jatuh.
5.2 Connecting a Load
- Matikan: Turn off the power supply before connecting any load.
- Sambungkan Petunjuk: Connect the positive (+) lead from your load to the red Positive Output Terminal (+) and the negative (-) lead from your load to the black Negative Output Terminal (-). Ensure connections are secure.
- Hidupkan kuasa: Turn on the power supply. The displays will show the actual voltage, current, and power being delivered to the load.
- Memutuskan sambungan: Always turn off the power supply before disconnecting the load.
6. Penyelenggaraan
Penyelenggaraan yang betul memastikan ketahanan dan operasi bekalan kuasa anda yang boleh dipercayai.
- Pembersihan: Regularly clean the exterior of the unit with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure no liquids enter the unit.
- Pengudaraan: Periodically check the cooling fan and ventilation openings for dust accumulation. Use compressed air to gently clear any blockages. A blocked fan can lead to overheating.
- Penggantian fius: If the unit fails to power on, the fuse may need replacement. Ensure the power supply is disconnected from the mains before attempting to replace the fuse. The fuse holder is located on the rear panel. Replace with a fuse of the same type and rating only.
- 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.
