4A DC-DC Step-down Adjustable Constant Voltage Module

The 4A DC-DC Step-down Adjustable Constant Voltage Module offers adjustable output voltage ranging from 1.5V to 35V, catering to various needs. Capable of delivering a wide range of current outputs up to 4A, this module ensures versatility for high-power applications. When equipped with a heat sink and cooling fan, it efficiently manages continuous high-power operations.

Crafted with a dedicated benchmark IC and high-precision current sensing resistor, this module guarantees stable constant current, exhibiting minimal temperature drift (less than 1% from 20°C to 100°C), making it particularly suitable for LED driver applications. Its output current can reach up to 4A, meeting diverse demands.

Enhanced stabilization in output voltage is achieved through four high-frequency capacitances, ensuring lower output ripple. The double heat sink design facilitates rapid heat dissipation, with independent heat sinks for MOS Schottky diodes, preventing interference. Additionally, the utilization of a large-sized Sendust Core and double pure copper wiring improves efficiency while reducing heat.

Featuring onboard 3296 multiturn potentiometers for precise voltage and current regulation, this module ensures stability. Its adjustable voltage and current capabilities make it user-friendly and applicable across multiple scenarios such as battery charging, LED driver power supply, and vehicle power supply. With its wide range of applications and cost-effectiveness, this module remains highly sought-after among makers.
