DC-DC 80W 5A Adjustable Buck-Boost Power Supply Module with LCD Display

This module is a versatile DC-DC converter module with automatic buck-boost operation. It efficiently steps up or down DC voltage, making it ideal for powering electronics from variable input sources like solar panels, batteries, or automotive systems. Featuring a crisp full-view LCD screen, rotary control, and programmable protections, it's perfect for DIY labs, battery charging, and embedded systems.

Key Features:

  • Automatic Buck-Boost Mode: Accepts input both above and below the target output voltage
  • Adjustable Output Voltage & Current: Fully configurable constant voltage (CV) and constant current (CC) modes
  • Large HD LCD Screen: Displays voltage, current, power, energy, time, and input voltage
  • Rotary Encoder + Buttons: Intuitive control with rotary knob and three buttons (SW, V/A, ON/OFF)
  • Multiple Protection Modes: Over-voltage, over-current, over-power, over-temperature, reverse polarity, timeout, and more
  • Soft Start & Reverse Input Protection: Safe power-up and secure operation

How to Use:

  1. Connect Input Power: Supply DC voltage (6V–36V) to VIN+ and VIN- terminals.
  2. Set Output Values:
    • Short press V/A to enter voltage/current setting.
    • Use the rotary knob to adjust values.
    • Press again to switch between voltage and current.
    • Press and hold SW to access advanced settings.
  3. Monitor Values:
    • OLED shows input/output voltage, output current, power, energy, time.
    • Press SW to toggle input/output view.
    • Short press the encoder to scroll stats.
  4. Control Output:
    • Press ON/OFF to enable or disable the output.
    • Hold ON/OFF to clear accumulated stats.

Application Examples:

  • Constant current driver for high-power LEDs
  • Battery chargers (Li-ion, NiMH, lead-acid)
  • Solar/wind energy regulation
  • Adjustable lab power supply
  • Voltage stabilizer for automotive/marine systems
  • Field-testing tool for electronics repair

Note:

  • Do not connect AC power directly.
  • Input voltage must always be higher than battery voltage when used as a charger.
  • Ensure adequate cooling if drawing high power continuously.
  • Always connect the input before connecting a battery load.
