Youmile 6PACK Step-Down Power Supply Module LM2596 LM2596S Buck Converter DC to DC 3.0-40V to 1.5-35V High Efficiency Voltage Regulator Module

• 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
• Features: all use high quality solid-state capacitors, 36 u thickening circuit boards, high-Q inductance with LED indicator output
• Quantity: 6 pieces; Size: 43 x 21 x 14mm/1.7 x 0.8 x 0.6inch (with potentiometer)
• 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)

Description: 100% Brand New and High Quality Name: LM2596S Step-down Module; The input voltage: DC 3.2V~46V; The output voltage: DC 1.25V~35V (Adjustable); The output current: 3A (Max) Conversion efficiency: 92% (highest); The output ripple: less than 30mV; Switching frequency: 65KHZ; Working temperature: -45?~+85?; Size: 43 x 21 x 14mm/1.7 x 0.8 x 0.6inch With power supply indicator light; IN+ input positive; IN- input negative; OUT+ output positive; OUT- output negative; Input voltage range: DC 3.2V to 46V (input voltage must be 1.5V higher than output voltage. Can't booster); Output voltage range: DC 1.25V to 35V adjustable, high efficiency (92%), maximum output current is 3A,When 12v input, 5v output 1A current, load regulation less than 1%. Note: 1. This is step-down module, the input voltage must be higher than the output voltage; 2. Output below 2A can work without heat sink, when output current more than 2.5A (or output power more than 10W) to work long hours please add heat sink. 3. Potentiometer adjustment: Clockwise voltage increases, counterclockwise voltage decreases. Rotate a circle about 1V. Package Included: 6 x LM2596S Step-Down Module 2 x 30cm/11.8inch Power Wire
