5. Instellen
5.1 bedradingsverbindingen
- Ingangsvermogen: Connect your DC power source (10V-65V) to the 'IN+' and 'IN-' terminals. Ensure correct polarity.
- Uitgangsbelasting: Connect your load device to the 'OUT+' and 'OUT-' terminals. Again, verify correct polarity.
- Beveiligde verbindingen: Ensure all wire connections are tight and secure to prevent loose contacts or short circuits.
5.2 Montage
Mount the module in a stable location that allows for proper airflow, especially around the cooling fan and heat sink. Avoid enclosed spaces that could lead to heat buildup.

6. Gebruiksaanwijzing
6.1 Inschakelen
Once wired correctly, apply power to the input terminals. The LED display will illuminate, showing the current output voltage or other default parameters.
6.2 Het uitgangsvolume aanpassentage en stroom
The module features operation key buttons for precise adjustment:
- Deeltage-instelling: Press the 'SET' button to enter voltage adjustment mode. Use the adjustment buttons (usually up/down arrows or rotary encoder, if present) to increase or decrease the voltage value. Press 'OK' to confirm and save the setting.
- Huidige instelling: Similarly, press 'SET' to cycle to current adjustment mode. Adjust the current value using the appropriate buttons and confirm with 'OK'.
- Realtime weergave: The LED display shows real-time output voltage and current. It can also display capacity and time, which can be cycled through using the buttons.
6.3 Statusindicatoren
The module includes LED indicators to show its operating status:
- UIT: Licht op wanneer de uitgang actief is.
- cv (constante voltage): Illuminates when the module is operating in constant voltage-modus.
- CC (Constant Current): Illuminates when the module is operating in constant current mode.
6.4 Geavanceerde functies
- Automatic Output: The module can be configured to automatically enable output upon power input. Refer to the specific button sequence for this setting.
- Knopvergrendelingsmodus: To prevent accidental changes to settings, the parameter adjustment buttons can be locked. Consult the device's specific button combination for this function.
7. Onderhoud
Regular maintenance ensures optimal performance and longevity of your DROK DC Buck Converter:
- Schoonmaak: Keep the module clean and free from dust and debris. Use a soft, dry cloth for cleaning. Do not use liquid cleaners.
- Koelsysteem: Periodically check that the cooling fan and heat sink fins are free from obstructions to ensure efficient heat dissipation.
- Verbindingen: Regularly inspect all input and output wiring connections for tightness and signs of wear or corrosion.
- Opslag: When not in use for extended periods, store the module in a dry, cool, and dust-free environment.
