Product Description (Detailed):

The 12A Adjustable DC-DC Buck Converter Module is a high-performance power supply board that efficiently steps down a higher DC voltage (e.g., 24V) to a stable, lower output voltage (e.g., 12V). This module supports up to 12 amps of current and is built with constant voltage (CV) and constant current (CC) modes, making it ideal for both LED lighting and battery charging applications.

Equipped with a charging indicator LED, onboard heat sink, and multi-turn potentiometers for precise voltage and current adjustment, this module is excellent for use in DIY electronics, industrial controls, automotive setups, or as a bench power supply.

Key Features:

• 12A High-Current Buck Converter: Step down 24V DC to 12V or adjustable output for powering LEDs, batteries, and DC loads.

• Constant Current Output: Built-in constant voltage + constant current (CV/CC) mode supports safe battery charging and LED driving.

• LED Charging Indicator: Onboard indicator LED shows charging status or load connection, ideal for battery-powered applications.

• Overcurrent & Thermal Protection: Integrated safety features protect the module and connected devices from overload or overheating.

• Wide Applications: Suitable for DC-DC regulation, LED strip drivers, power tools, electric vehicle accessories, and lab power supply projects.

How to Use:

Basic Setup:

1. Connect Input Voltage:

   • VIN+ → Positive of your 24V DC source

   • VIN− → Ground/Negative of the power supply

2. Connect Output Load:

   • VOUT+ → Positive to LED or battery/device

   • VOUT− → Ground to load

3. Adjust Voltage and Current:

   • Use the voltage trimmer (CV) to set desired output voltage.

   • Use the current trimmer (CC) to limit the max output current.

Usage Tips:

• Use a voltmeter/multimeter while adjusting to avoid overshooting voltage.

• Ensure proper heat dissipation above 6A or 100W load.

• Ideal for 12V LED strip lights, 12V batteries (Li-ion, lead acid), motor drivers, and regulated outputs for sensors/microcontrollers.

Applications:

• LED drivers and lighting systems

• Lithium-ion battery and SLA battery chargers

• Step-down power conversion in automotive setups

• Bench power supplies for labs and repair shops

• Constant current driver for laser modules or power tools

• Voltage regulation in solar projects or EV accessories

Package Includes:

• 1 × 12A DC-DC Adjustable Buck Converter Module
