DROK 24V to 12V 5V DC to DC Buck Step Down Voltage Converter 16-40V to 1.0-12V 6A Synchronous Rectifier Regulator High Efficiency Power Charging DIY Module 16-40V to 1.0-12V DC synchronous rectification buck converter. Light load maximum efficiency of the module is up to 98%. It can works stably at 6A continuous output current, strengthening ventilation it can work at 8A above current. This module has under-voltage shutdown, over-current shutdown protect function, please avoid frequently short-circuit when in normal output working state. When your need large current output, please use the two-terminal wiring, welding directly is better.
