High efficiency, 0-5A (with low ripple) Max) It is a 180 KHz fixed frequency PWM buck DC/DC module that can drive an adjustable load. It has overcurrent protection features. It has adjustable output voltage and current. Since it has CC CV capability, it can also be used as a special charger for Lithium Batteries (Li-Ion, LiPo).
Except for input and output screw terminal connectors There are two multi-turn trimpots to adjust the output voltage and output current. Additionally, there are three LED indicators – the first one next to the input connector is a constant current (cc) indicator, while the next two LEDs are designed mainly for battery charging applications (battery charge and battery full indicators). However, when used as a general-purpose power supply, the battery charge indicator LED will operate as a "charge" indicator.
Turn the voltage setting (V-ADJ) clockwise. Turning it slowly will gradually raise the output voltage, and turning it counterclockwise will lower it. Likewise, turning the current adjustment (I-ADJ) trimmer clockwise increases the current limit, while counterclockwise movement decreases the current limit. It is recommended to adjust the voltage level first, then the current level.
