ITEM NAME:DC-DC Step Down Power Module DC 4.5V-48V LM2596HVS Buck Regulator Board A#S Product Description Description: LM2596HVS DC-DC Step Down Power Module DC 4.5V-48V Buck Voltage Adjustable Regulator Converter Board Description: 1. Input voltage: 4-48V, pay attention to the limit value of 48V, absolutely must not exceed. 2. As the input voltage increases, the output power of the LM2596HVS IC becomes smaller and the operational stability deteriorates. Stable operation between 36V-40V. 3. Adjustment Method: First correctly connect the input power (between 4-48V) and then monitor the output voltage with a multimeter and adjust the potentiometer. Specifications: Type/Name: LM2596HVS DC-DC Step-Down Module Input Voltage: 4.5V-48V Output Voltage: 3V-40V Output Current: 3A (Maximum) Conversion Efficiency: 92% (The Highest) Output Ripple:
