Feature: 1. This is a DC‑DC step down converter module that convert 6.5V‑60V to 3.3-40V, maximum current is 5A 2. Step down converter module is used for voltage step‑down so please make sure that input voltage is higher than output voltage 3. The step down module can be remarkably efficient (maximum 97%), making it useful for voltage step‑down 4. Input and output are designed with screw terminals for convenient connection 5. Widely used for lithium or lead‑acid battery, low voltage system power supply, 6V, 12V, 14V, 24V battery charging and regulated power supply Specification: Features: This is a DC-DC step down converter module that convert 6.5V-60V to 3.3-40V, maximum current is 5A.
