4. Arahan Persediaan
Follow these steps to safely set up your ALITOVE power supply:
- Pemasangan: Securely mount the power supply in a well-ventilated area using the integrated mounting tabs. Ensure it is away from flammable materials and sources of heat or moisture.
- Sambungan Input AC: Connect your AC power source (110V or 220V) to the 'L' (Live) and 'N' (Neutral) terminals. Use appropriate gauge wiring for your region and load.
- Sambungan Tanah: Connect the earth ground wire from your AC source to the terminal marked with the ground symbol (⏚). This is crucial for safety.
- Sambungan Output DC: Connect your 12V DC device to the 'V+' (positive) and 'V-' (negative) terminals. Ensure correct polarity to prevent damage to your device.
- Sahkan Sambungan: Double-check all wiring connections for tightness and correct polarity before applying power. Loose connections can cause overheating or malfunction.
- Vol. Awaltage Check (Optional but Recommended): Before connecting your sensitive device, you may wish to power on the unit and use a multimeter to verify the output voltage at the V+ and V- terminals.
Nota: Jika unit anda mempunyai voltage selector switch (110V/220V), ensure it is set correctly for your local mains voltage before connecting AC power.
5. Arahan Operasi
Once properly set up, operating the power supply is straightforward:
- Hidupkan kuasa: Apply AC power to the unit. The indicator light should illuminate, signifying that the power supply is active.
- Voltage Pelarasan: If your application requires a precise 12V output or a slightly different voltage within the 10% adjustment range, use a small screwdriver to carefully turn the potentiometer labeled '+V ADJ'. Turn clockwise to increase voltage, counter-clockwise to decrease. Monitor the output with a multimeter during adjustment.
- Pemantauan: The power supply is designed for continuous operation within its specified limits. Ensure the connected load does not exceed 5 Amps atau 60 Watt.
- Matikan: Disconnect the AC input power when the unit is not in use or when performing maintenance.
