5. Persediaan dan Pemasangan
Follow these steps for proper installation of your Mean Well LRS-150-24 power supply. Ensure all power is disconnected before proceeding.
5.1 Input Voltage Pemilihan
The power supply features a switch to select the input voltage. Before connecting the AC input, verify that the switch is set to the correct voltage (115V or 230V) for your region. Incorrect selection can lead to damage.
5.2 Sambungan Pendawaian
The power supply has clearly labeled terminal blocks for AC input and DC output. Use appropriate gauge wires for your application.
- AC Input (L, N, ⊗): Connect your mains AC power to the 'L' (Live), 'N' (Neutral), and '⊗' (Ground) terminals.
- DC Output (+V, -V): Connect your LED lighting load to the '+V' (Positive) and '-V' (Negative) terminals. Ensure correct polarity.

The following video demonstrates the general wiring process for a similar 24V power supply. While the exact model may differ, the principles of connecting AC input and DC output to LED strips are applicable.
6. Arahan Operasi
Once properly installed and wired, the Mean Well LRS-150-24 operates automatically. Ensure the connected LED load does not exceed 150W. The unit provides a constant 24V DC output.
- Hidupkan kuasa: Apply AC power to the input terminals. The power supply will immediately provide 24V DC output.
- Matikan: Disconnect AC power from the input terminals to turn off the power supply.
- Perlindungan Lebihan: If the load exceeds the rated power, the unit's overload protection will activate, potentially shutting down the output. Reduce the load and cycle power to reset.
7. Penyelenggaraan
The Mean Well LRS-150-24 power supply is designed for long-term, reliable operation with minimal maintenance. However, periodic checks can help ensure optimal performance:
- Pembersihan: Ensure the unit's ventilation holes are free from dust and debris to maintain proper cooling. Use a soft, dry cloth or compressed air for cleaning.
- Sambungan: Periodically check all wiring connections to ensure they are secure and free from corrosion. Loose connections can cause intermittent operation or overheating.
- Persekitaran: Confirm the operating environment remains within specified temperature and humidity ranges.
