Buck converter module with USB interface, constant current regulation and adjustable 5A voltage

Welcome to our shop! Discover our step-down voltage power supply module, a versatile and precise tool for all your electronic projects. This module combines functionality, safety, and ease of use in a compact format. **Main Features:** **Versatile Uses:** Acts as a standard buck converter, a charger for various batteries (lithium, lead-acid, etc.), and a constant current driver for high-power LEDs. It effectively replaces a multimeter thanks to its integrated voltmeter, ammeter, and wattmeter displays, providing a clear visualization. **Dual Operating Modes:** Operates in constant voltage (CV) or constant current (CC) mode. An indicator light shows the active mode. **Easy Adjustment:** For battery charging, you can precisely adjust the float voltage and charging current. A light indicator signals the status (charging in progress / charging complete).* **Enhanced Safety:** Protected against short circuits (current limiting) and overheating (thermal protection with automatic shut-off). The module will not burn out even in the event of a short circuit at the output.* **High Precision:** The integrated voltmeter and ammeter can be self-calibrated to ensure consistently accurate measurements.* **Convenient USB Interface:** Equipped with a USB port for charging your digital devices. Note: The USB output voltage is equal to the module's set output voltage and is not fixed at 5V. Check compatibility before use.**Detailed Technical Specifications:** **Item Type:** Buck Converter Power Supply Module** **Input Voltage:** 5V - 36V DC** **Output Voltage:** Continuously adjustable from 1.25V to 32V** **Output Current:** Adjustable, maximum 5A (recommended use below 4.5A)** **Output Power:** Maximum 75W (recommended use below 50W.
