DC - DC Step down converter voltage regulator Variable 1.5~35 V BE1
Variable power supply module LM2596 Step down transformer Buck transformer
These modules are great for providing a variable voltage across a wide range of applications.
Just to clarify, these modules reduce/limit DC voltage.
Input voltage: 3.2-40V DC Output Voltage: 1.5-35V DC(adjustable) input must be at least 1.5V higher than desired output. Output current: rated current 2A, maximum 3A (a suitable heatsink will be required if over 2A is being drawn) Conversion efficiency:Up to 92% Dynamic response speed: 5% 200uS. Circuit protection: SS36. Operating temperature: (-40 ? to +85 ?) (output power 10W or less). Load regulation: ± 0.5%. Size: 50 mm x 23 mm. Clockwise rotation of each potentiometer will increase each relative output. Ships with each set at about 4.5v 1A limited output
Input and output terminals are capable of accepting wire up to 2mm diameter and can be soldered.
