Input: DC 3 V to 40 V (input voltage must be 1.5 V higher than the output voltage, no boost) Output: DC 1.5 V to 35 V voltage is continuously adjustable, maximum output current is 3 A Steps: connect to power source, adjust the swirl button on the blue potentiometer and monitor voltage with multimeter to get the needed voltage (The factory have tested these at max voltage so they are very high by default, takes about 15-20 turns CCW before the voltage starts ramping down) Features: all use SANYO solid-state capacitors, 36 u thickening circuit boards, high-Q inductance with LED indicator output Quantity: 10 pieces buck converter; Size: 45 * 20 * 14 mm LM2596 LM2596S DC-DC Step Down Variable Volt Regulator Input 3.0-40V Output 1.5-35V Adjustable Buck Converter Electronic Voltage Stabilizer Power Supply ModuleKindly Note:1. Input voltage must be 1.5 V higher than the output voltage, no boost2. could you please dont reverse the input and output interface3. Keep output under 2.5A and use a heat sink when for a long time workingSpecifications:Model: LM2596Input voltage: DC 3V - 40VOutput Voltage: DC 1.5V - 35V (adjustable)Output Current: 3A (max)Conversion Efficiency: 92% (max)Switching Frequency : 65KHzRectification: non-synchronous rectificationModule property: non-isolated buck moduleOperating Temperature: -45℃ to +85℃Load Regulation: ± 0.5%Voltage Regulation: ± 2.5%Package List:10 x LM2596 DC-DC Buck Converter Module.
