Identyfikacja komponentu:

Figure 3.1: Labeled diagram of the module's main components.

This image illustrates the key connection points and controls on the module. Observe the "Input +" and "Input -" terminals for power input, and "Output +" and "Output -" for power output. The "CV" (Constant Voltage) and "CC" (Constant Current) potentiometers are used for adjustment. The "IN/OUT" and "ON/OFF" buttons control display and output respectively. The LCD screen displays operational parameters.

5. Konfiguracja

Follow these steps to set up your DC-DC Buck Boost Converter Module:

1. Przygotuj połączenia: Ensure all power sources are disconnected before making any wiring.
2. Połączenie wejściowe: Connect your DC power source to the "Input +" and "Input -" terminals. Observe polarity: positive to "Input +" and negative to "Input -". The module has input reverse protection, but correct connection is always recommended.
3. Połączenie wyjściowe: Connect your load or device to the "Output +" and "Output -" terminals. Observe polarity: positive to "Output +" and negative to "Output -".
4. Początkowe uruchomienie: Once all connections are secure, apply power to the input terminals. The LCD display should illuminate, showing the current input or output voltage.
5. Rozpraszanie ciepła: For continuous operation at higher currents (above 3A) or power (above 35W), ensure adequate heat dissipation. This may involve attaching the included heatsink or providing active cooling.

This image shows the module alongside an aluminum heatsink. For operations requiring higher current or power, attaching this heatsink to the main power components on the module is recommended to prevent overheating and ensure stable performance.

6. Instrukcja obsługi

The module features two buttons and two potentiometers for control and adjustment.

Funkcje przycisków:

• Przycisk wejścia/wyjścia:
  • Krótkie naciśnięcie: Switches the LCD display between input voltage i wyjście voltage.
  • Długie naciśnięcie: Switches the LCD display between output current and output power.
• Przycisk WŁ./WYŁ.:
  • Krótkie naciśnięcie: Toggles the output ON or OFF.
  • Długie naciśnięcie: Sets the default output state (ON or OFF) for the next power-up. The setting is saved.

Potentiometer Adjustments:

Figure 6.1: Close-up of adjustment potentiometers and LCD.

Na tym obrazie przedstawiono szczegółowo view of the two potentiometers, labeled "CV" and "CC", located near the output terminals. These are used for fine-tuning the output voltage i aktualne limity.

• CV (stała objętośćtage) Potentiometer:
  • Rotate clockwise to increase the output voltage.
  • Rotate counter-clockwise to decrease the output voltage.
  • Adjust this to set your desired output voltage.
• CC (Constant Current) Potentiometer:
  • Rotate clockwise to increase the current limit.
  • Rotate counter-clockwise to decrease the current limit.
  • When the load current reaches the set current, the module enters constant current (CC) mode, and the red "CC" indicator light will illuminate. This protects the load and the module from overcurrent.

Ważny: Always adjust the CV potentiometer first to set the desired voltage, then adjust the CC potentiometer to set the maximum current limit for your application. If charging a battery, set the voltage slightly higher than the battery's full charge voltage and the current to the desired charging current. The module will automatically switch to constant voltage mode when the battery is nearly full.

7. Konserwacja

• Czyszczenie: Keep the module clean and free from dust. Use a soft, dry cloth to wipe the surface. Do not use liquids or abrasive cleaners.
• Rozpraszanie ciepła: Regularly check that the heatsink (if installed) is free from dust and debris to ensure efficient cooling. Ensure adequate airflow around the module, especially during high-power operation.
• Znajomości: Okresowo sprawdzaj wszystkie połączenia przewodów, aby mieć pewność, że są solidne i nie są skorodowane.
• Składowanie: Gdy moduł nie jest używany, należy przechowywać go w suchym i chłodnym miejscu, z dala od bezpośredniego światła słonecznego i ekstremalnych temperatur.
