10pcs 5A DC to DC CC CV Lithium Battery Step down Charging Board Converter Power Supply Led Lithium Battery Charger Step Down Module XL4015Description:This is a set of 10pcs dc-to-dc buck(step-down) power converter modules that step down the voltage from their input (power) to their output (load). These buck module can be extremely efficient (imum 96%), which makes them useful for Step-down voltage, that the input voltage is higher than the output voltage, such as battery, power transformer, DIY regulated power supply, laptop power supply for car and industrial equipment. Features: These are converter modules used to step down the voltage that the input voltage is higher than the output voltage. The input voltage range is from 4V to 38V DC, and the output voltage can be adjusted from 1.25V to 36V. These buck module can be extremely efficient, and imum efficiency can be up to 96%), making them very useful. This kit contains a total of 10 pieces of DC-DC buck modules, which can be used for a wide variety of projects. These are great step-down modules for battery, power transformer, DIY regulated power supply, laptop power supply for car and industrial equipment.
