6. Impostazione

6.1 Fisico Oltreview

Immagine 1: Davanti view of the DORHEA Buck Boost Converter. This image shows the main display screen, the rotary encoder knob for adjustments, and the ON/OFF button. The display is active, showing output voltage (05.00V), current (0.121A), and power (00.60W).

Immagine 2: Top-down view of the converter's internal components. This image highlights the cooling fan, inductors, capacitors, and the screw terminals for input and output connections. The fan is centrally located for heat dissipation.

6.2 Dimensioni e montaggio

Immagine 3: Dimensional drawing of the converter. This image provides key measurements for the device, including a length of 79mm (3.11in), width of 43mm (1.69in), and height of 53mm (2.09in). These dimensions are crucial for enclosure design and mounting.

The converter is designed for panel mounting. The cutout dimensions required for installation are approximately 72 mm x 40 mm, con un 12mm x 2.5mm notch centered on each narrow side for securing the unit.

6.3 Collegamenti di cablaggio

Identify the input and output terminals on the back of the module. These are typically labeled:

• VIN+: Positive input voltage
• VIN-: Negative input voltage (Ground)
• FUORI+: Positive output voltage
• FUORI-: Negative output voltage (Ground)

Use appropriate gauge wires for your input power source and load. Ensure all connections are secure within the screw terminals. For stranded wires, it is recommended to twist and tin the ends with solder for a more reliable connection.

7. Istruzioni per l'uso

7.1 Accensione/spegnimento

Once wired, apply input power. The unit will typically power on automatically. Use the dedicated ACCESO/SPENTO button on the front panel to toggle the output power.

7.2 Regolazione del volumetage e attuale

The rotary encoder knob is used to adjust parameters. Press the knob to select a parameter (e.g., voltage or current). Rotate the knob to change the value. You may need to cycle through digit positions to set precise values. Press the knob again to confirm or move to the next digit/parameter.

7.3 Display Pages and Settings

The converter features multiple display pages that can be cycled through to view various operational parameters:

• Ingresso/Uscita Voltage(V)
• Corrente (A)
• Temperatura (T)
• Potenza (W)
• Electric Capacity (AH)
• Electric Quantity (WH)
• Tempo di esecuzione
• Voltage and Current Graphs
• Impostazioni dei parametri di sistema

Refer to the on-screen menu for navigation and customization options, which may include flipping or rotating the display, changing background and parameter colors, and switching between day and night display modes.

7.4 Constant Current (CC) Function

The constant current function allows the module to maintain a set output current regardless of load changes (within its operational limits). This is particularly useful for charging batteries or driving LEDs that require a stable current. To use this function, set the desired current limit. The module will then regulate the output current to this value.

7.5 Funzioni di protezione

The module includes several built-in protection features:

• Over-Voltage Protezione (OVP): Shuts down output if voltage supera un limite stabilito.
• Protezione da sovracorrente (OCP): Limits or shuts down output if current exceeds a set limit.
• Protezione da sovratensione (OPP): Limits or shuts down output if power exceeds a set limit.
• Basso volumetage Protezione (LVP): Shuts down output if input voltage scende al di sotto di una soglia impostata.
• Protezione da sovratemperatura (OTP): Shuts down output if the module's temperature becomes too high.
• Protezione inversa: Protects against damage from incorrect input polarity.
• Protezione da cortocircuito: Protects against damage from output short circuits.

These protections are designed to safeguard both the converter and the connected load. If a protection is triggered, the display will typically indicate the fault.

8. Manutenzione

• Pulizia: Keep the module clean and free from dust. Use a soft, dry cloth for cleaning. Avoid using liquids or solvents.
• Heat Sink/Fan: Periodically check the cooling fan for obstructions and ensure it operates freely. Ensure the heat sink is securely attached to the components for effective heat dissipation. If the heat sink or fan circuit board appears loose, it can be secured with a small amount of non-conductive adhesive.
• Connessioni terminali: Regularly inspect screw terminal connections to ensure they remain tight and secure. Loose connections can lead to intermittent operation or overheating.

9. Risoluzione Dei Problemi

• Nessuna uscita Voltage:
  • Check input power supply and connections.
  • Ensure the ON/OFF button has been pressed to enable output.
  • Verify that no protection functions (e.g., OVP, OCP, LVP) have been triggered.
• Inaccurate Output Voltage/Corrente:
  • Use a calibrated external multimeter to verify the output.
  • Ensure the load is not drawing more current than the set limit or the module's maximum capacity.
  • If significant discrepancies persist, the unit may require calibration or be faulty.
• Surriscaldamento del modulo:
  • Reduce the load or ensure it is within the 80W power limit.
  • Check for proper ventilation around the module.
  • Ensure the cooling fan is operating correctly and not obstructed.
• Intermittent Operation or Display Issues:
  • Check all wiring connections for looseness.
  • Inspect the internal circuit board, especially the heat sink/fan board, for any loose connections or components. Gently re-seat or secure if necessary (e.g., with a small dab of hot glue on non-critical areas).
