ITEM NAME:LM2596HV DC-DC 5-55V to 1.25-30V 15W Step Down Buck Power Supply Module Board Product Description Description: Specifications: Module properties: non-isolated step-down constant current and constant voltage module (CC CV) charging module Input Voltage: 5-55V (Limit Voltage 55V) Output voltage: 1.25-30V adjustable Minimum Voltage Difference 2V: Input Voltage must be higher than 2V Output Voltage, not boost Output current: 12V to 5V maximum 3A (output other voltage according to 15W formula 15/output voltage = output current) Output power: maximum 15W. (If the temperature is high, please install radiator) Conversion efficiency: 80% (higher output voltage, higher efficiency) Working temperature: industrial grade (- 40℃~ + 85℃) (ambient temperature over 40 degrees, please reduce power use, or enhance heat dissipation) Full Load Temperature Rise: 45℃ No-load current: typical 10mA (48V to 4.2V) Potentiometer regulation direction: general clockwise (increase), counterclockwise (decrease) Indicator lamp: double color indicator lamp, red indicator lamp in charging, green indicator lamp after charging (no load is green) Module size: 48*24*11mm/1.88*0.94*0.43'' Packing weight: 15g Operation Manual: In order to be safe, please try to leave some margin. When the input and connection battery is full, the maximum voltage should be considered. The output voltage must not be adjusted to more than 35v, and the output power (product of voltage and current) should not exceed 10w. 1. Fixed switching lamp current is 0.1 times the constant current value (used to identify whether the battery is full when charging); 2. The input reverse protection diode is added, and the input reverse protection diode forms a circuit, consumes the reverse energy and protects the module; if the reverse energy is too large and the current increases sharply, the S-shaped line on F1 on PCB will be burned off to form an open circuit, which further protects the module; at this time, only one is connected.Output power: maximum 15W. Full Load Temperature Rise: 45℃. Included: 1 X DC-DC 5-55V to 1.25-30V Step Down Module. Module size: 48 24 11mm/1.88 0.94 0.43". Indicator lamp: double color indicator lamp, red indicator lamp in charging, green indicator lamp after charging (no load is green).
