Precauções de segurança
Always observe the following safety precautions to prevent injury or damage to the module:
- Garantir o volume de entradatage is within the specified range (90-264 Vac).
- Não exceda a corrente máxima de saída de 0.6A.
- Avoid direct contact with the module's pins when power is applied.
- Install the module in a well-ventilated area to prevent overheating.
- Ensure proper insulation and clearance from other components.
- This module is intended for integration into larger electronic systems by qualified personnel.
Configurar
1. Configuração de pinos
The HLK-PM01 module has clearly labeled pins for input and output connections.
Figura 2: Angulado view of the HLK-PM01 module, highlighting the input (AC) and output (+Vo, -Vo) pins.
- Entrada CA: Two pins for AC line voltage (90-264V).
- +Vo Output: Positive 5V DC output.
- -Vo Output: Negative (Ground) 5V DC output.
2. Conexão elétrica
- 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.
- Certifique-se de que todas as conexões estejam seguras e devidamente isoladas para evitar curtos-circuitos.
Observação: 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.
Instruções de operação
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.
Manutenção
The HLK-PM01 module is designed for maintenance-free operation. However, periodic checks are recommended:
- Inspeção visual: Periodically inspect the module and its connections for any signs of physical damage, loose wires, or discoloration.
- Remoção de poeira: Ensure the module is free from excessive dust accumulation, which can impede heat dissipation. Use a soft brush or compressed air if necessary.
- Monitoramento 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.
Solução de problemas
| Problema | Possível causa | Solução |
|---|---|---|
| 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. |
| Volume de saídatage instável ou baixo | Overload condition; Poor connections; Input voltage flutuações. | 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. |
