1. Pengenalan
This manual provides detailed instructions for the ASHATA Multi-Channel Switching Power Supply Module, featuring the LM2596 chip. This module is designed to provide stable and accurate voltage outputs for various electronic applications, offering 3.3V, 5V, 12V, and an adjustable (ADJ) output channel. Please read this manual thoroughly before use to ensure proper operation and safety.
2. Maklumat Keselamatan
- Sentiasa pastikan volum inputtage is within the specified range (DC 5-40V). Exceeding this range can damage the module.
- Observe correct polarity when connecting input and output power. Incorrect connections can lead to damage.
- Avoid short circuits on the output terminals. While the module has overcurrent protection, prolonged short circuits can cause stress or damage.
- Do not touch the module components while it is powered on, as some parts may become hot.
- Keep the module away from moisture, dust, and extreme temperatures.
- This module is intended for use by individuals familiar with electronic components and circuits.

- Sambungkan Kuasa Input: Connect your DC power source (5V-40V) to the input terminals labeled 'INPUT' and 'GND' on the module. Ensure correct polarity.
Rajah 2: Bawah view of the module, indicating input and output labels for wiring.
- Sambungkan Peranti Output: Connect your devices requiring 3.3V, 5V, or 12V to the corresponding output terminals. Each output has dedicated terminals for power and ground.
- Adjust ADJ Output (if needed): If using the adjustable output channel, connect a voltmeter to the 'ADJ' output terminals. Use a small screwdriver to carefully turn the blue potentiometer (trimmer) located on the board to set the desired voltage. Pusing mengikut arah jam untuk meningkatkan volumtage, lawan arah jam untuk berkurangan.

Once all connections are secure and verified, the module is ready for operation.
6. Arahan Operasi
After completing the setup:
- Apply Input Power: Turn on your DC power source connected to the module's input.
- Sahkan Output: Use a voltmeter to confirm the output voltages (3.3V, 5V, 12V, and ADJ) are correct before connecting sensitive devices.
- Sambungkan Beban: Connect your electronic devices to the appropriate output terminals. Ensure the total current draw does not exceed the module's capacity for each channel.
- Pantau Prestasi: Observe the stability of the output voltages during operation. The integrated overcurrent protection will activate if a channel draws excessive current, potentially shutting down that output to prevent damage.
7. Penyelenggaraan
To ensure the longevity and optimal performance of your power supply module:
- Pembersihan: Periodically clean the module with a soft, dry cloth to remove dust. Do not use liquids or abrasive cleaners. Ensure the module is powered off and disconnected from all sources before cleaning.
- Storan: When not in use, store the module in a dry, cool environment, away from direct sunlight and corrosive substances.
- Pemeriksaan: Regularly inspect the module for any signs of physical damage, loose connections, or discoloration of components.
8. Penyelesaian masalah
| Masalah | Kemungkinan Punca | Penyelesaian |
|---|---|---|
| Tiada keluaran voltage | No input power; incorrect input polarity; module damage; overcurrent protection activated. | Check input power source and connections. Verify input polarity. Disconnect load and re-test. If problem persists, module may be damaged. |
| Keluaran tidak betul voltage (ADJ channel) | Potentiometer not set correctly. | Adjust the blue potentiometer with a voltmeter connected to the ADJ output until the desired voltage dicapai. |
| Keluaran voltage drops under load | Load current exceeds channel capacity; input voltage terlalu rendah. | Reduce the load on the affected channel. Ensure input voltage is stable and within the 5-40V range. |
| Module becomes excessively hot | Excessive load; insufficient ventilation. | Reduce the load. Ensure adequate airflow around the module. Consider adding a heatsink if operating at high loads continuously. |
