Feature: This is a DC-DC step down converter module that convert 6.5V-60V to 1.25-30V, maximum current is 10A. Buck converter module is used for voltage step-down so please make sure that input voltage is higher than output voltage. The buck module can be remarkably efficient (maximum 97%), making it useful for voltage step-down. Input and output are designed with screw terminals for convenient connection. Widely used for low voltage system power supply, 6V, 12V, 14V, 24V battery charging and regulated power supply. Specifications: DC-DC synchronous rectification adjustable step-down module Input: 6.5V-60V Output: 1.25-30V (adjustable) Efficiency: 97% (MAX) Module size: (L) 75mm x (W) 21mm x (H) 16mm Working temperature: -4 - +85 degC Load capacity: up to 10A Wiring method: the terminal is free of soldering, IN is input, OUT is output DIY Supplies:Electrical Package List: 1 x Module
