4. Identificación de componentes

Figura 4.1: Front panel controls and indicators. The 'SW' key switches display modes, 'U/I' key selects voltage/current adjustment, 'CC' indicates constant current mode, 'ON' indicates output enabled, and the rotary encoder adjusts values.

Figura 4.2: Internal components and connection points. The input terminals are labeled IN+ and IN-, while the output terminals are OUT+ and OUT-. The fan and heat sink are visible for thermal management.

5. Instrucciones de configuración

1. Apagado: Asegúrese de que todas las fuentes de alimentación estén desconectadas antes de realizar cualquier conexión.
2. Conexión de entrada: Connect your DC power source (6.0V-36V) to the EN+ y EN- terminals. Observe polarity: EN+ for positive, EN- for negative. The module has reverse polarity protection, but correct wiring is always recommended.
3. Conexión de salida: Conecte su carga a la FUERA+ y AFUERA- terminals. Observe polarity: FUERA+ for positive, AFUERA- para negativo.
4. Conexiones seguras: Ensure all wire connections are tight and secure to prevent loose contacts and potential damage.
5. Encendido inicial: After verifying all connections, apply power to the input. The LCD display should illuminate.

6. Instrucciones de funcionamiento

6.1. Modos de visualización

• Presione el SW key to cycle through different display modes: input voltage, volumen de salidatage, output current, output power, output capacity (Ah), and output time (h).
• The display will show 'IN' for input parameters and 'OUT' for output parameters.

6.2. Ajuste del volumen de salidatage y Actual

1. Volumentage Ajuste: Presione el U/I key until the voltage value on the display starts blinking. Rotate the rotary encoder clockwise to increase the voltage and counter-clockwise to decrease it. Press U/I again to confirm the setting or wait a few seconds for it to auto-confirm.
2. Current Limit Adjustment: Presione el U/I key until the current value on the display starts blinking. Rotate the rotary encoder to set the desired current limit. Press U/I again to confirm. The 'CC' indicator will light up when the module operates in constant current mode.

6.3. Output Enable/Disable

• Presione el ENCENDIDO/APAGADO button (often integrated with the rotary encoder or a separate button) to enable or disable the output. The 'ON' indicator light will show the output status.

7. Mecanismos de protección

The module incorporates several software protection features with adjustable thresholds. If any operating parameter exceeds its set threshold, the output will automatically be disabled to protect the module and the connected load.

• Input Anti-Reverse Protection: Prevents damage from incorrect input polarity.
• Output Anti-Reverse Protection: Protects the module if a reverse voltage is applied to the output.
• Subvol. de entradatagProtección electrónica (UVP): Ajustable de 5.8V a 36V (predeterminado 5.8V).
• Sobrevoltaje de salidatagProtección electrónica (OVP): Ajustable de 0.6V a 36V (predeterminado 36V).
• Output Overcurrent Protection (OCP): Adjustable from 0A to 5A (default 5A).
• Output Overpower Protection (OPP): Adjustable from 0W to 80W (default 80W).
• Protección contra sobretemperatura (OTP): Adjustable from 80°C to 110°C (default 110°C).
• Timed Protection (OHP): Adjustable from 0 to 100 hours (default off).
• Overcapacity Protection (OAP): Adjustable from 0 to 60Ah (default off).

To adjust protection thresholds, refer to the detailed instructions provided with the product packaging or manufacturer's website, as the exact button sequence may vary slightly.

8. Mantenimiento

• Limpieza: Keep the module clean and free from dust. Use a soft, dry cloth for cleaning. Do not use liquids or abrasive cleaners.
• Ventilación: Ensure the fan and ventilation openings are not obstructed to maintain proper airflow and cooling. Periodically check for dust buildup on the fan blades and heat sink.
• Almacenamiento: Guarde el módulo en un entorno seco y fresco, alejado de la luz solar directa y de temperaturas extremas.
• Conexiones: Revise periódicamente todas las conexiones eléctricas para verificar que estén bien ajustadas y que no presenten signos de desgaste o corrosión.

9. Solución de problemas

• Sin pantalla/Sin energía:
  • Verifique la fuente de alimentación de entrada y las conexiones. Asegúrese de que el volumen de entradatage está dentro de 6.0 V-36 V.
  • Verifique la polaridad de entrada correcta.
• Ninguna salida:
  • Ensure the output is enabled (check 'ON' indicator).
  • Check for active protection (e.g., OVP, OCP, OTP indicators). If a protection is triggered, the output will be disabled. Address the cause (e.g., reduce load, check temperature) and re-enable output.
  • Verify output connections and load.
• Vol de salidatage/Corriente no estable:
  • Ensure input power is stable and sufficient for the desired output.
  • Compruebe si hay conexiones sueltas.
  • If operating near maximum power (80W) or current (5A), ensure adequate cooling. The intelligent fan should activate.
• El ventilador no funciona:
  • The fan is temperature-controlled. It will only activate if the internal temperature exceeds 50°C or the output current exceeds 1A. This is normal operation.
  • If the module is hot and current is high, but the fan is not running, check for obstructions or fan malfunction.
