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

Welcome to our store! Discover our voltage step-down power supply module, a versatile and precise tool for all your electronic projects. This module combines functionality, security and ease of use in a compact form factor.**Key Features:*** **Versatile Uses:** Acts as a standard buck module, a charger for various batteries (lithium, lead, etc.) and a constant current driver for high power LEDs. It advantageously replaces a multimeter thanks to its integrated voltmeter, ammeter and wattmeter displays, offering clear visualization.* **Dual Operating Mode:** Operates in constant voltage (CV) or constant current (CC) mode. An indicator light indicates active mode.* **Easy Setting:** For battery charging, you can precisely adjust the end-of-charge voltage (float voltage) and the charging current.A light indicator signals the status (charging in progress / charging completed).* **Reinforced security:** Protected against short circuits (current limitation) and overheating (thermal protection with automatic shutdown). The module does not burn out even in the event of a short circuit at the output.* **High Precision:** The built-in voltmeter and ammeter can be self-calibrated to ensure always accurate measurements.* **Convenient USB Interface:** Equipped with a USB port for charging your digital devices. Note: The USB output voltage is equal to the set output voltage of the module, and is not fixed at 5V.Check compatibility before use.**Detailed Technical Specifications:*** **Item type:** Step-down power supply module (Buck Converter)* **Input voltage:** 5V - 36V DC* **Output voltage:** Continuously adjustable from 1.25V to 32V* **Output current:** Adjustable, maximum 5A (recommended use under 4.5A)* **Output power:** Maximum 75W (recommended use under 50W.Reduce power in case of large voltage difference between input and output).* **Conversion efficiency:** Up to 96%* **Working frequency:** 180 kHz* **Operating temperature:** -40°C to +85°C* **Protections:** * Short circuit protection (current limitation): Yes * Overheat protection: Yes (automatic shutdown) * Reverse voltage protection Input polarity: No (add a diode in series if necessary)* **Dimensions:** Approximately 68.2mm (L) x 38.8mm (W) x 15mm (H)* **Connection method:** Screw or solder terminals.
