سيٽ اپ ڪريو
1. پن ترتيب
The HLK-PM01 module has clearly labeled pins for input and output connections.

شڪل 2: زاويه view of the HLK-PM01 module, highlighting the input (AC) and output (+Vo, -Vo) pins.
- AC ان پٽ: Two pins for AC line voltage (90-264V).
- +Vo Output: Positive 5V DC output.
- -Vo Output: Negative (Ground) 5V DC output.
2. بجليءَ وارا ڪنيڪشن
- Identify the AC input terminals on the module. Connect your AC power source (90-264V) to these two terminals.
- Identify the +Vo and -Vo output terminals. Connect the positive input of your 5V DC load to +Vo and the negative/ground input to -Vo.
- پڪ ڪريو ته سڀئي ڪنيڪشن محفوظ ۽ صحيح طرح سان موصل آهن ته جيئن شارٽ سرڪٽ کان بچي سگهجي.
نوٽ: For optimal performance and safety, consider adding appropriate input filtering and output capacitance as per your application's requirements, although the module has internal filtering.
آپريٽنگ هدايتون
Once the module is correctly wired, operation is straightforward:
- Apply AC power to the input terminals. The module will immediately begin converting the AC voltage to a stable 5V DC output.
- Monitor the load to ensure it operates within the module's specified output current (max 0.6A).
- The module is designed for continuous operation within its specified parameters.
The module features built-in overload and short-circuit protection. In case of an overload or short circuit, the module will automatically protect itself and resume normal operation once the fault condition is removed.
سار سنڀال
The HLK-PM01 module is designed for maintenance-free operation. However, periodic checks are recommended:
- بصري چڪاس: Periodically inspect the module and its connections for any signs of physical damage, loose wires, or discoloration.
- مٽي هٽائڻ: Ensure the module is free from excessive dust accumulation, which can impede heat dissipation. Use a soft brush or compressed air if necessary.
- درجه حرارت جي نگراني: While operating, the surface temperature of the main converter should not exceed 90°C, and the shell surface maximum temperature should not exceed 60°C. Ensure adequate ventilation.
Do not attempt to open or repair the module. Refer to qualified personnel for any issues beyond basic inspection.
مشڪلاتون
| مسئلو | ممڪن سبب | حل |
|---|---|---|
| 5V آئوٽ پُٽ ناهي | No AC input power; Incorrect wiring; Module failure. | Verify AC input power supply. Check all wiring connections for correctness and security. If wiring is correct and power is present, the module may be faulty and require replacement. |
| volاھر وولٽtage unstable or low | Overload condition; Poor connections; Input voltage fluctuations. | Reduce the load current to below 0.6A. Ensure all connections are firm. Verify the stability of the AC input voltage. |
| Module is hot | Excessive load; Insufficient ventilation. | Ensure the load current does not exceed 0.6A. Provide adequate airflow around the module. |
| Module shuts down intermittently | Overload protection triggered; Short circuit detected. | Check for intermittent short circuits or transient overloads on the output. The module should resume operation once the fault is cleared. |
