상품특징
Input voltage range： DC 3 -40 V (input voltage must be 1.5 V higher than the output voltage, no boost)Output voltage range：Output: DC 1.5 - 35 V voltage is continuously adjustable, maximum output current is 3 A8 pieces of LM2596 board and heat sinks includedEasy to make it work and convenient to accurately adjust the output voltage with a mini screwdriver.100% SATISFICATION SERVICE: If there are any problem with our products, please feel free to contact us. you can request a refund for any single module and no need to return it.; Any problems you can contact us and we will try our best to resolve it till you satisfied.（Note：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)
상품설명
Product FeaturesParameters:Input Voltage: DC 3 -40 VOutput Voltage: DC 1.5 - 35 VOutput Current: 3A[MAX] It is recommended to use under 2A [NOTE: When using high power, add a heat sink to the power supply chip]Load adjust ratio: +/-0.5% Voltage adjust ratio: +/-2.5% Transferring efficiency: 92% Max[the higher output voltage, the higher efficiency] ON/OFF frequency: 150KHz Output ripple: 200mV Module feature: buck and non-isolated Rectification method: non-synchronous rectification Size: 5.4x2.3x1.8CM Weight: 16g Fuction:1.Built in over-temperature protection function 2.Built in current limit function 3.Built in output short-circuit protection function How to use1.Access the power supply [ 3 -40 V], the power indicator light, the module is working properly.2.Adjust the blue potentiometer knob [usually clockwise rotation boost, counterclockwise rotation Step-down] and monitor the output voltage with a multimeter to reach the required voltage. 3.A customer reflects the module output voltage can not be adjusted, always equal to the input voltage. When you encounter this problem, please first counterclockwise rotation potentiometer 10 laps above, and then use the module can be normal adjustment of the voltage.Package includes: 8X LM2596 board8 pieces of heat sink
