Hiletgo LM2596 DC-DC Buck Converter Module with LED Voltmeter

1. ആമുഖം

This manual provides detailed instructions for the safe and effective use of the Hiletgo LM2596 DC-DC Buck Converter Module. This module is designed to step down a higher DC input voltage to a lower, adjustable DC output voltage, featuring an integrated LED voltmeter for real-time voltagഇ നിരീക്ഷണം.

2. സുരക്ഷാ മുൻകരുതലുകൾ

• Always ensure correct polarity when connecting input and output power. Incorrect connections can damage the module and connected devices.
• പരമാവധി ഇൻപുട്ട് വോള്യത്തിൽ കവിയരുത്tage or output current ratings.
• Avoid short circuits on the output.
• Ensure proper ventilation, especially when operating at higher currents, as the module may generate heat.
• This module is intended for experienced users familiar with electronics.

The module consists of the following key components:

• Input Terminals (IN+/IN-): For connecting the DC power source.
• Output Terminals (OUT+/OUT-): For connecting the load.
• LED Voltmeter Display: Shows either the input or output voltage.
• Potentiometer (Trimmer): A blue multi-turn potentiometer used to precisely adjust the output voltage.
• ബട്ടണുകൾ:
  • "IN/OUT" Button: Toggles the LED display between showing the input voltagഇ, ഔട്ട്പുട്ട് വോളിയംtage. A small indicator LED will illuminate next to 'IN' or 'OUT' on the display to show the current mode.
  • "ON/OFF" Button: Toggles the LED voltmeter display on or off.

5.1 പ്രാരംഭ സജ്ജീകരണം

1. Connect Input Power: Connect your DC power source to the "IN+" (positive) and "IN-" (negative) screw terminals. Ensure correct polarity. The input voltage must be within the 4.0V to 40V range.
2. Connect Load (Optional for initial adjustment): If you are adjusting the voltage without a load, you can skip this step for now. For operation, connect your load to the "OUT+" (positive) and "OUT-" (negative) screw terminals, observing polarity.
3. പവർ ഓൺ: Apply power to the input terminals. The LED voltmeter should light up, displaying the current output voltagഇ ഡിഫോൾട്ടായി.

5.2 Adjusting Output Voltage

• Use a small Phillips or flat-head screwdriver to turn the blue potentiometer (trimmer) located on the module.
• Turning the potentiometer clockwise will increase the output voltage.
• Turning the potentiometer counter-clockwise will decrease the output voltage.
• Monitor the LED display to set the desired output voltagഇ. ഔട്ട്പുട്ട് വോളിയംtage 1.25V മുതൽ 37V വരെ ക്രമീകരിക്കാം.

5.3 Using the LED Voltmeter

• Toggle Display (IN/OUT Button): Press the button labeled "IN/OUT" to switch the LED display between showing the input voltagഇ, ഔട്ട്പുട്ട് വോളിയംtage. An indicator LED (small dot) will show which voltage is currently being displayed.
• Toggle Display ON/OFF (ON/OFF Button): Press the button labeled "ON/OFF" to turn the LED voltmeter display on or off. This can be useful to reduce power consumption or if the display is not needed.

6. പരിപാലനം

• Keep the module clean and free from dust and moisture.
• Regularly check connections for tightness and corrosion.
• If operating at high currents (e.g., close to 3A), ensure adequate heat dissipation. Consider adding a small heat sink to the LM2596 chip.
• Do not attempt to modify the circuit board unless you are a qualified electronics technician.
