Configuración
1. Configuración do pin
The HLK-PM01 module has clearly labeled pins for input and output connections.
Figura 2: En ángulo view of the HLK-PM01 module, highlighting the input (AC) and output (+Vo, -Vo) pins.
- Entrada AC: Two pins for AC line voltage (90-264V).
- +Vo Output: Positive 5V DC output.
- -Vo Output: Negative (Ground) 5V DC output.
2. Conexión eléctrica
- 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.
- Asegúrate de que todas as conexións estean seguras e debidamente illadas para evitar curtocircuítos.
Nota: 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.
Instrucións de funcionamento
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.
Mantemento
The HLK-PM01 module is designed for maintenance-free operation. However, periodic checks are recommended:
- Inspección visual: Periodically inspect the module and its connections for any signs of physical damage, loose wires, or discoloration.
- Eliminación de po: Ensure the module is free from excessive dust accumulation, which can impede heat dissipation. Use a soft brush or compressed air if necessary.
- Monitorización de temperatura: 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.
Resolución de problemas
| Problema | Causa posible | Solución |
|---|---|---|
| No 5V output | 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. |
| Vol. De saídatage inestable ou baixo | Overload condition; Poor connections; Input voltage flutuacións. | 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. |
